This brake package for the BMW E70 X5 xDrive 35iX (N55 turbo engine) comes with everything you need to perform a major brake overhaul --

Front and rear brake rotors with hardware
Front and rear brake pads
Front and rear pad wear sensors
Brake fluid

Our brake package uses the same replacement parts from the same manufacturers as BMW dealers use to service your car. The big difference is that we're able to offer these parts for a substantial savings from the dealer markup price. As an independent company we're able to buy our parts from multiple OEM suppliers whereas BMW dealers must buy their parts from BMW. We're able to shop from different vendors which gets you a better price while still maintaining original quality. You don't have to pay high prices at the dealer to get the same quality and performance!

In some cases, we offer performance alternatives to the OEM items. For an enthusiastic BMW owner, the standard BMW part may be inadequate and we offer an upgraded part, based on our 20 years of BMW tuning experience. We seek out high quality suppliers and designs that we would want on our own vehicles. Many times performance parts will fix a design flaw with the original BMW part, improving your performance at the same time.

This item fits the following BMWs:
2011-2013 E70 BMW X5 xDrive35i

The stock M5 brakes provide a powerful upgrade over the stock brakes on non-M E60 models - 525i, 528i, 530i, 535i, 545i, and 550i. This kit uses the factory E60 M5 front 2-piston calipers with M5 rotors for a bolt on braking upgrade. Everything comes complete - 2-piston calipers, rotors, caliper bracket, stainless brake lines, and a pad sensor. Each rotor option is similar to the factory 2-piece floating and drilled rotors. Choose your preferred brake rotors, brake pads, and brake fluid from the options below (or call us for a recommendation).

Brake rotor options -

• Zimmermann Coated
• Genuine BMW
• Centric/StopTech Coated
• ECS 2-piece Floating Drilled + Slotted

Brake pad options -

• Centric Posi-Quiet street (nearly dust-free!)
• OEM Pagid or Textar street
• Cool Carbon performance
• Hawk HPS performance
• Hawk Ceramic street (nearly dust-free!)
• StopTech performance

This is a direct fit to all non-M E60 RWD models and comes with a lot more braking power than standard. Consequently there will be more front brake bias - the front brakes have more bite than before. During normal street driving all you will notice is that the brakes feel stronger. For track driving we recommend a more aggressive rear pad to balance the brake bias or a StopTech or Brembo big brake kit that has been properly engineered for the chassis (not a retrofit).

Requires 18" wheels and wheel spacers may be required depending on wheel spoke design.

F30 M Performance brakes for your E9X 325/328/330/335! This kit uses the factory M Performance front and rear Brembo multi-piston calipers and rotors for a bolt on braking upgrade. Everything comes complete -

The ECS M Performance Big Brake Kit includes:

• Orange 4 Piston Brembo front calipers from the F3X M Performance brake kit 
• Orange 2 Piston Brembo rear calipers from the F3X M Performance brake kit (custom machined, with brackets)
• Front 370x30mm ECS 2-piece rotors
• Rear 350x24mm ECS 2-piece rotors
• ECS Exact-Fit Stainless Steel Brake Lines
• Genuine BMW front & rear brake pad set (use any M Performance - fitment brake pad)
• Class 12.9 mounting hardware, brake fluid, pad wear sensors

Performance:

• Bias - 63.3% front, 36.7% rear – optimally balanced for the e9x chassis
• Brake torque – 4% increase results in more responsive braking system
• Pedal feel – firmer pedal feel for improved modulation
• Improved cooling & heat management - brake deeper, harder, with less fade

More on ECS Exact-Fit Stainless Steel Brake Lines (the same tried-and-true style you've probably been running for years):

• Independently tested for DOT compliance to the FMVSS 571.106 standard for brake lines
• Volumetric expansion verified at 17% of the maximum allowable for low expansion hose at 1500 psi, with a burst strength of nearly 2.5x the required minimum.
• Tensile pull strength of nearly double the minimum requirement. Whip resistance of over double the required test limit. Passes 24hr salt spray test with flying colors 24hr salt spray test - no white or red rust.
• Exceptional resistance to expansion under extreme line pressure results in improved pedal feel and braking response. Each line quality inspected and pressure tested to 3000psi.

More on ECS 2 piece Cross-Drilled/Slotted Rotors: 

• Weight savings: save 2 lbs per axle versus the genuine BMW rotor.
• Increased thermal capacity and Improved cooling:  
  • Heat convection (due to air flow) is considered the most important mode of heat dissipation in rotor design. The key to this is adequate air flow through the rotor.
  • ECS 2-Piece rotors feature side-specific directionally curved vanes which pump air through the rotor at a higher velocity, leading to consistent, rapid cooling on both sides equally.   
  • The air velocity in curved vane rotors is higher than pillar-post rotors and straight vane rotors, and as such curved vane rotors have been shown to cool more effectively.
• Manufacturing quality: Manufactured exclusively for ECS Tuning in an ISO 9001 certified facility
• Testing:  ECS 2-piece rotors have been subjected to thousands of miles of hard street use and to the elements (including snow and salt) for years. They have also been subjected to scientific brutal stress testing on the track and brake dyno, performing countless high-speed stops in quick succession.  We have measured stopping distances and elevated rotor temperatures of over 1000*F for long sustained periods (to the point of rotor bluing and catching brake pads on fire), as well as subjecting rotors to careful post-test inspection for signs of irregular wear, warping, stress cracking, or any other signs of failure.

• ECS rotors have proven themselves to be robust, demonstrating excellent wear characteristics, no warping, no thermal stress cracking, no signs of hot spots and minimal pad glazing.​

This is a direct fit to all non-M E9X and comes with a lot more braking power than standard (especially on non-335 models). You can use any F30 brake pad with these (OE BMW come standard) so there are a lot of street and track pad options. The rear calipers have been especially modified to work with the ECS caliper bracket.

Requires 18" wheels and wheel spacers may be required depending on wheel spoke design.
