BMW StopTech Big Brake Kits

BMW StopTech Big Brake Kits

Even the average BMW enthusiast can quickly exceed the stock brake's performance threshold. Factor in increased horsepower, better suspensions, stickier tires, and multiple high speed stops any stock braking system will show its shortcomings. Stock brakes were designed to be used in day-to-day traffic with light pedal pressure and stops from low speeds. They are absolutely unsuitable for regular hard use, either on the street or a racetrack.

Upgrading pads is only the first step - it works for most people who do not regularly push their cars to the absolute limit. But all cars capable of serious speeds should have serious brakes. The real key to better brakes is heat management and bigger is better. Brake rotors act as heat banks - a larger rotor simply has more capacity to store heat. StopTech has also designed their discs with better internal cooling vanes to dissipate the heat faster. Combined with aluminum calipers and rotor hats, this all combines to prevent heat from being trapped and soaking into the components. If not sufficiently released, heat soak will eventually reach into the brake fluid, causing more serious and immediate braking issues. Their engineeering and expertise is why you will find StopTech Brakes on our Turner Motorsport racecars and has led them to Tier 1 OEM status (a direct supplier to several vehicle manufacturers), four industry patents, and TUV and ISO/TS Quality Management System certification for brake systems and components. StopTech Brakes are among the best in the world for performance and racing braking systems. Made in the USA.

StopTech 6 Piston Trophy Front Big Brake Kit - E46 M3

Position: Front
Caliper: 6-piston Trophy STR
Colors: Natural Anodized
Rotors: 355 or 380x32mm, cross-drilled or slotted
Also Included: stainless steel brake lines, StopTech Street Performance pads, hardware

StopTech Trophy Kits feature floating, slotted StopTech AeroRotors, stainless steel brake lines, and race engineered caliper brackets, as well as ultra-high performance StopTech STR lightweight forged calipers in six-piston, four-piston or two-piston configurations. Easily identifiable by their unique shape and finish, StopTech Trophy Big Brake Kit components feature a MIL-spec hard-anodizing on the Trophy STR calipers and AeroHats that is impervious to color change or fading at extreme race temperatures. There are two types of StopTech Trophy Big Brake Kits available - Trophy Race for the track and Trophy Sport for the street. 

Safety Improvements from A Big Brake Kit:
+ Caliper design improves brake application and increases torque - braking is stronger meaning shorter stopping distances and faster response
+ Vehicle-specific design - improves brake feel with a firmer pedal
+ Larger and thicker rotors - less fade and longer pad and rotor life

Advantages of a StopTech Big Brake Kit:
+ extremely strong caliper and mounting system - reduces flex and deflection, improving torque application to the disc
+ Several color options available
+ Vehicle-specific calipers that maintain correct brake proportioning and balance
+ AeroRotor patented vaning for superior air flow
+ Cross-Drilled for street use or Gas-Slotted for street or track use
+ Billet aluminum mounting hats for superior strength over steel
+ DOT-compliant stainless steel brake lines
+ Street Performance brake pads that work on both street and light track use

Maximizing brake efficiency by braking with all four wheels... Sounds obvious right? Many bolt-on caliper upgrades and other big brake kits are not built with the specific vehicle's dynamics in mind. With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better...

Wheel Fitment Guides: Wheel spoke-to-brake caliper clearance is critical since the new caliper is physically larger and the in a different position. StopTech has produced these cutaway diagrams for you to print and place on the backside of your wheel to check for clearance. Wheels that do not clear will need a wheel spacer. The minimum recommended clearance between the wheel and caliper is 3mm.

StopTech builds each kit around the specific vehicle, engineering the system to achieve the correct brake balance. This brake upgrade gives better stopping performance in everyday driving, aggressive street driving, or all-out track days. By increasing the rotor size, using a larger pad, and a fixed forged aluminum caliper, you can improve your braking performance substantially for any condition! StopTech Brakes have been used on Turner Motorsport racecars since 2003, winning 5 sports car championships and recording numerous race wins since.

Safety Improvements from A Big Brake Kit:
+ Caliper design improves brake application and increases torque - braking is stronger meaning shorter stopping distances and faster response
+ Vehicle-specific design - improves brake feel with a firmer pedal
+ Larger and thicker rotors - less fade and longer pad and rotor life

Advantages of a StopTech Big Brake Kit:
+ extremely strong caliper and mounting system - reduces flex and deflection, improving torque application to the disc
+ Several color options available
+ Vehicle-specific calipers that maintain correct brake proportioning and balance
+ AeroRotor patented vaning for superior air flow
+ Cross-Drilled for street use or Gas-Slotted for street or track use
+ Billet aluminum mounting hats for superior strength over steel
+ DOT-compliant stainless steel brake lines
+ Street Performance brake pads that work on both street and light track use

Maximizing brake efficiency by braking with all four wheels Sounds obvious right? Many bolt-on caliper upgrades and other big brake kits are not built with the specific vehicle's dynamics in mind. With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better

Wheel Fitment Guides: Wheel spoke-to-brake caliper clearance is critical since the new caliper is physically larger and the in a different position. StopTech has produced these cutaway diagrams for you to print and place on the backside of your wheel to check for clearance. Wheels that do not clear will need a wheel spacer. The minimum recommended clearance between the wheel and caliper is 3mm.

StopTech 4 Piston Rear Big Brake Kit - E46 M3

Position: Rear
Caliper: 4-piston ST40
Colors: black, red, silver, blue, yellow
Rotors: 332x32mm, cross-drilled or slotted
Also Included: stainless steel brake lines, StopTech Street Performance pads, hardware

StopTech Brakes puts championship-winning race technology and state-of-the-art engineering under your feet. StopTech's Front Big Brake Kit for the M3 is a model-specific brake upgrade engineered to work with the stock brake hydraulics and ABS/DSC system. StopTech builds each kit around the specific vehicle, engineering the system to achieve the correct brake balance. This brake upgrade gives better stopping performance in everyday driving, aggressive street driving, or all-out track days. By increasing the rotor size, using a larger pad, and a fixed forged aluminum caliper, you can improve your braking performance substantially for any condition! StopTech Brakes have been used on Turner Motorsport racecars since 2003, winning 5 sports car championships and recording numerous race wins since.

Safety Improvements from A Big Brake Kit:
+ Caliper design improves brake application and increases torque - braking is stronger meaning shorter stopping distances and faster response
+ Vehicle-specific design - improves brake feel with a firmer pedal
+ Larger and thicker rotors - less fade and longer pad and rotor life

Advantages of a StopTech Big Brake Kit:
+ extremely strong caliper and mounting system - reduces flex and deflection, improving torque application to the disc
+ Several color options available
+ Vehicle-specific calipers that maintain correct brake proportioning and balance
+ AeroRotor patented vaning for superior air flow
+ Cross-Drilled for street use or Gas-Slotted for street or track use
+ Billet aluminum mounting hats for superior strength over steel
+ DOT-compliant stainless steel brake lines
+ Street Performance brake pads that work on both street and light track use

Maximizing brake efficiency by braking with all four wheels... Sounds obvious right? Many bolt-on caliper upgrades and other big brake kits are not built with the specific vehicle's dynamics in mind. With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better...

StopTech Front Big Brake Kit (355mm) 4-Piston - E39 540i, M5

Position: Front
Caliper: 4-piston ST40
Colors: black, red, silver, blue, yellow, custom (call)
Rotors: 355x32, cross-drilled or slotted
Also Included: stainless steel brake lines, StopTech Street Performance pads, hardware

StopTech Brakes puts championship-winning race technology and state-of-the-art engineering under your feet. StopTech's Front Big Brake Kit for the E39 540i and M5 is engineered to work with the stock brake hydraulics and ABS/DSC system. StopTech builds each kit around the specific vehicle, engineering the system to achieve the correct brake balance. This brake upgrade gives better stopping performance in everyday driving, aggressive street driving, or all-out track days. By increasing the rotor size, using a larger pad, and a fixed forged aluminum caliper, you can improve your braking performance substantially for any condition! StopTech Brakes have been used on Turner Motorsport racecars since 2003, winning 5 sports car championships and recording numerous race wins since.

Safety Improvements from A Big Brake Kit:
+ Caliper design improves brake application and increases torque - braking is stronger meaning shorter stopping distances and faster response
+ Vehicle-specific design - improves brake feel with a firmer pedal
+ Larger and thicker rotors - less fade and longer pad and rotor life

Advantages of a StopTech Big Brake Kit:
+ extremely strong caliper and mounting system - reduces flex and deflection, improving torque application to the disc
+ Several color options available
+ Vehicle-specific calipers that maintain correct brake proportioning and balance
+ AeroRotor patented vaning for superior air flow
+ Cross-Drilled for street use or Gas-Slotted for street or track use
+ Billet aluminum mounting hats for superior strength over steel
+ DOT-compliant stainless steel brake lines
+ Street Performance brake pads that work on both street and light track use

Maximizing brake efficiency by braking with all four wheels Sounds obvious right? Many bolt-on caliper upgrades and other big brake kits are not built with the specific vehicle's dynamics in mind. With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better

Big brake kits have larger components than the factory brakes. Some wheel designs and sizes may not clear without wheel spacers. StopTech has produced a template that has all of the critical dimensions of this brake kit. You can download and print it here and then check the clearance on your wheels.

Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better...

Big brake kits have larger components than the factory brakes. Some wheel designs and sizes may not clear without wheel spacers. StopTech has produced a template that has all of the critical dimensions of this brake kit. You can download and print it here and then check the clearance on your wheels.

Easily identifiable by their unique shape and finish, StopTech Trophy Big Brake Kit components feature a MIL-spec hard-anodizing on the Trophy STR calipers and AeroHats that is impervious to color change or fading at extreme race temperatures. There are two types of StopTech Trophy Big Brake Kits available - Trophy Race for the track and Trophy Sport for the street. 

Safety Improvements from A Big Brake Kit:
+ Caliper design improves brake application and increases torque - braking is stronger meaning shorter stopping distances and faster response
+ Vehicle-specific design - improves brake feel with a firmer pedal
+ Larger and thicker rotors - less fade and longer pad and rotor life

Advantages of a StopTech Big Brake Kit:
+ extremely strong caliper and mounting system - reduces flex and deflection, improving torque application to the disc
+ Several color options available
+ Vehicle-specific calipers that maintain correct brake proportioning and balance
+ AeroRotor patented vaning for superior air flow
+ Cross-Drilled for street use or Gas-Slotted for street or track use
+ Billet aluminum mounting hats for superior strength over steel
+ DOT-compliant stainless steel brake lines
+ Street Performance brake pads that work on both street and light track use

Maximizing brake efficiency by braking with all four wheels... Sounds obvious right? Many bolt-on caliper upgrades and other big brake kits are not built with the specific vehicle's dynamics in mind. With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better...

Maximizing brake efficiency by braking with all four wheels... Sounds obvious right? Many bolt-on caliper upgrades and other big brake kits are not built with the specific vehicle's dynamics in mind. With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better...

Wheel Fitment Guides: Wheel spoke-to-brake caliper clearance is critical since the new caliper is physically larger and the in a different position. StopTech has produced these cutaway diagrams for you to print and place on the backside of your wheel to check for clearance. Wheels that do not clear will need a wheel spacer. The minimum recommended clearance between the wheel and caliper is 3mm.

StopTech Brakes puts championship-winning race technology and state-of-the-art engineering under your feet. StopTech's Front Big Brake Kit for the E36/E46 is a model-specific brake upgrade engineered to work with the stock brake hydraulics and ABS/DSC system. StopTech builds each kit around the specific vehicle, engineering the system to achieve the correct brake balance. This brake upgrade gives better stopping performance in everyday driving, aggressive street driving, or all-out track days. By increasing the rotor size, using a larger pad, and a fixed forged aluminum caliper, you can improve your braking performance substantially for any condition! StopTech Brakes have been used on Turner Motorsport racecars since 2003, winning 5 sports car championships and recording numerous race wins since.


Safety Improvements from A Big Brake Kit:
+ Caliper design improves brake application and increases torque - braking is stronger meaning shorter stopping distances and faster response
+ Vehicle-specific design - improves brake feel with a firmer pedal
+ Larger and thicker rotors - less fade and longer pad and rotor life

Advantages of a StopTech Big Brake Kit:
+ extremely strong caliper and mounting system - reduces flex and deflection, improving torque application to the disc
+ Several color options available
+ Vehicle-specific calipers that maintain correct brake proportioning and balance
+ AeroRotor patented vaning for superior air flow
+ Cross-Drilled for street use or Gas-Slotted for street or track use
+ Billet aluminum mounting hats for superior strength over steel
+ DOT-compliant stainless steel brake lines
+ Street Performance brake pads that work on both street and light track use

Maximizing brake efficiency by braking with all four wheels... Sounds obvious right? Many bolt-on caliper upgrades and other big brake kits are not built with the specific vehicle's dynamics in mind. With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better...

With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better...

StopTech Rear Big Brake Kit - E70 X5, E71 X6

Position: Rear (must be used with front StopTech kit)
Caliper: 4-piston ST41
Colors: black, red, silver, blue, yellow, custom (call)
Rotors: 380x32, cross-drilled or slotted
Also Included: stainless steel brake lines, StopTech Street Performance pads, hardware

StopTech Brakes puts championship-winning race technology and state-of-the-art engineering under your feet. StopTech's Rear Big Brake Kit for the E70 X5 and E71 X6 is engineered to work with the stock brake hydraulics and ABS/DSC system. StopTech builds each kit around the specific vehicle, engineering the system to achieve the correct brake balance. This brake upgrade gives better stopping performance in everyday driving, aggressive street driving, or all-out track days. By increasing the rotor size, using a larger pad, and a fixed forged aluminum caliper, you can improve your braking performance substantially for any condition! StopTech Brakes have been used on Turner Motorsport racecars since 2003, winning 5 sports car championships and recording numerous race wins since.

Safety Improvements from A Big Brake Kit:
+ Caliper design improves brake application and increases torque - braking is stronger meaning shorter stopping distances and faster response
+ Vehicle-specific design - improves brake feel with a firmer pedal
+ Larger and thicker rotors - less fade and longer pad and rotor life

Advantages of a StopTech Big Brake Kit:
+ extremely strong caliper and mounting system - reduces flex and deflection, improving torque application to the disc
+ Several color options available
+ Vehicle-specific calipers that maintain correct brake proportioning and balance
+ AeroRotor patented vaning for superior air flow
+ Cross-Drilled for street use or Gas-Slotted for street or track use
+ Billet aluminum mounting hats for superior strength over steel
+ DOT-compliant stainless steel brake lines
+ Street Performance brake pads that work on both street and light track use

Maximizing brake efficiency by braking with all four wheels:
Sounds obvious right? Many bolt-on caliper upgrades and other big brake kits are not built with the specific vehicle's dynamics in mind. With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better.

Big brake kits have larger components than the factory brakes. Some wheel designs and sizes may not clear without wheel spacers. StopTech has produced a template that has all of the critical dimensions of this brake kit. You can download and print it here and then check the clearance on your wheels.
