This caliper bushing kit will eliminate flex caused by weak rubber caliper bushings. As the brake pedal is pressed the caliper grabs the rotor and twists on its mounting bushings. The rubber bushings allow the caliper to deflect and twist which affects pedal feel and results in uneven pad wear. These solid brass bushings will not twist or deflect so your calipers can squeeze the pads evenly on both sides of the rotor (sort of like what multi-piston big brakes do). This will give you much longer pad life and a more consistent pedal feel. This is the most complete kit we have ever sold with stainless steel caliper slide bolts, o-rings, and new dust boots. Unlike other kits, these bushings are pressed into the caliper and will not shift or slide on their own.

Installation is straightforward: remove the old rubber bushings and press in the new brass bushings (we recommend special tool 003326ECS03). High temp caliper grease or anti-seize is required. The new bushings include an inner o-ring that helps trap grease on the slide bolt, reducing friction and wear.

For most models with floating calipers. Fits the rear of E90/2 and E60, but for the front you'll need the kit found here. Does not fit E30 models with Girling calipers, but is compatible with Ate calipers. 

These 2-piece floating rotors help dissipate heat better than a standard cast iron rotor and are also lighter for less unsprung weight. Managing heat in the brake system is vital to braking performance, especially on the track or when driven hard. It's why your brake rotors have internal vanes that vent heat as the rotor spins. These 2-piece ECS rotors feature an outer cast iron friction surface ring that is separate from the aluminum center hat. This allows better airflow through the vanes and for the friction ring can expand as it gets hot. The rotors are also cross-drilled for better ventilation and slotted to improve brake pad performance.

ECS 2-Piece Rotors feature:

• Aluminum hats for light weight
• Heat-treated cast iron friction rings
• 2-piece assembly improves brake cooling
• Anti-corrosion coating on non-friction surfaces and hard anodizing on rotor hat

These are the same size as the stock rotors so your stock caliper and mounting bracket will fit and there will be no clearance issues with your wheels or to other components. Stainless steel rotor retaining screws are included. You can use these with any brake pad.

Price is for the pair of brake rotors.
