These braided stainless steel lines for the 2006+ E9X 3 Series and 2008+ E82 1 series improve the performance and safety of your BMW's braking system. They are DOT and German TUV approved, feature a resilient coating to protect against wear and chafing, and offer tremendous quality at a phenomenal price. These brake lines are made by renowned brake experts, Stoptech, and are ready for the rigors of daily street driving, driving schools, autocross and race events. Each set includes 6 brake lines as well as pre-installed grommets on the front for ideal fit.

Stoptech Stainless Steel Braided Brake Lines provide a quicker, firmer, more consistent pedal response by maintaining consistent brake pressure. Additionally, stainless steel lines provide precision brake modulation, especially during threshold braking. The improvement in pedal feel is more dramatic on older vehicles where the factory rubber line may have softened and swelled due to age.

StopTech brake lines consist of a PTFE (commonly referred to as Teflon) inner line that carries the brake fluid, which is then covered with a layer of stainless steel woven braid. The PTFE tube is very resistant to expansion under pressure and will not degrade from exposure to brake fluid.

The braided stainless steel provides support for the PTFE and the weave is extremely durable against incidental impact and abrasion. Next the stainless braided hose is coated with a clear abrasion resistant PVC cover for maximum protection against chaffing and strain relief devices reinforce end fittings.

These stainless brake lines fit the following BMWs:
2006+ E90 E92 E93 BMW 325i 328i 330i 335d 335i (RWD models)

Direct replacement Front gas-slotted brake discs for 2008+ E90 323i, E9X 328i/xi, E84 X1 28i. These rotors feature a unique black electro-coating that is designed to prevent corrosion. Each rotor is e-coated then double-ground and balanced to ensure an even surface with no vibration. The e-coating is the best anti-corrosion protection currently available in replacement rotors. Most aftermarket rotors are not coated, allowing surface rust to form right away, which is unattractive when brakes can be seen through your wheels.

Slotting a rotor helps to release gases that build up between the rotor surface and an out-gassing brake pad. Without an escape, this thin layer of gas will cause a delay until the pad cuts through gas layer. The slots in our rotors allow the gases to escape giving better braking performance. For track and racing use, slotting is preferred over cross-drilling because the slots don't take away as much mass from the rotor and won't suffer from structural cracks. Direct replacement for BMW # 34116855006 and 34116774875.

Sold as a FRONT pair.

StopTech Brakes puts championship-winning race technology and state-of-the-art engineering under your feet. StopTech's Front Big Brake Kit for the 328i/xi 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.

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.

Slotting a rotor helps to release gases that build up between the rotor surface and an out-gassing brake pad. Without an escape, this thin layer of gas will cause a delay until the pad cuts through gas layer. The slots in our rotors allow the gases to escape giving better braking performance. Cross-drilling a rotor is a way to improve initial pad bite. With the additional leading edges at each hole, the pad is able to grab the rotor just a little bit harder.

By combining both Cross-drilling and slotting, these rotors combine the best of both worlds. Fewer holes mean longer pad life with little penalty in the way of initial pad bite.

These rotors feature a unique black electro-coating that is designed to prevent corrosion. Each rotor is e-coated then double-ground and balanced to ensure an even surface with no vibration. The e-coating is the best anti-corrosion protection currently available in replacement rotors. Most aftermarket rotors are not coated, allowing surface rust to form right away, which is unattractive when brakes can be seen through your wheels.

+ 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 Brakes puts championship-winning race technology and state-of-the-art engineering under your feet. StopTech's Front Big Brake Kit for the 325xi/328xi 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

Direct replacement REAR gas-slotted brake discs for E9X 325. These rotors feature a unique black electro-coating that is designed to prevent corrosion. Each rotor is e-coated then double-ground and balanced to ensure an even surface with no vibration. The e-coating is the best anti-corrosion protection currently available in replacement rotors. Most aftermarket rotors are not coated, allowing surface rust to form right away, which is unattractive when brakes can be seen through your wheels.

Slotting a rotor helps to release gases that build up between the rotor surface and an out-gassing brake pad. Without an escape, this thin layer of gas will cause a delay until the pad cuts through gas layer. The slots in our rotors allow the gases to escape giving better braking performance. For track and racing use, slotting is preferred over cross-drilling because the slots don't take away as much mass from the rotor and won't suffer from structural cracks.

Sold as a REAR pair.

These rear brake discs / brake rotors fit:
2006 E90 320si, 325Xi sedan
2007-later E90 328Xi, 328i xDrive sedan
2006 E91 325Xi wagon
