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. 

Enhance your car's performance with ECS Tuning's polyurethane transmission mounts, designed for both street and track applications. These mounts are engineered to withstand high torque and forced-induction scenarios, eliminating concerns about torn mounts and providing a more engaging driving experience. Although polyurethane may introduce some additional NVH (Noise, Vibration, Harshness), its exceptional durability, wear resistance, and resistance to water, oil, and grease make it the perfect choice for performance enthusiasts. ECS Tuning offers two durometer options to match your driving style, along with a comprehensive DIY installation guide, ensuring a complete solution for your transmission mount requirements.

Key Features:

• Minimized transmission movement, reducing the risk of mis-shifts and over-revs.
• Made from high-quality polyurethane bonded with 304 Stainless Steel.
• Enhanced driving experience for both street and track enthusiasts.
• Two durometer options available: 80A for race applications and 70A for daily driving (ES#2859359).
• Replaces weak OEM mounts.

Drastically improve the looks of your vehicle while improving your vehicle's handling characteristics and/or easily adjust your wheel fitment to allow for the proper clearance when installing parts such as new wheels, big brake kits, or lowering suspension components.Interference from components such as shocks, springs, or control arms are a common issue when installing wheel that are not a direct OE size replacement. By moving your wheels a few millimeters each, you can give yourself enough clearance for proper wheel fitment and give your car a wider stance in the process.

ECS Tuning wheel spacers are constructed of high quality 6061-T6 aircraft grade aluminum and are specifically designed by in-house engineers and cnc machined to exact standards, ensuring the best fitment possible. By carefully measuring the OEM wheel hubs and bore dimensions, these spacers mount with minimal clearance to prevent any vibration, retaining the stock-like vibration free operation. 

This kit includes wheel bolts that are lab tested to meet or exceed ISO 898 class 10.9 mechanical and physical properties to ensure perfect fastening of the wheel to the hub with no issues or potential to snap under aggressive driving conditions.

ECS Tuning is a performance and genuine parts provider that designs their ECS Tuning branded aftermarket automotive parts in-house to ensure the highest quality and affordability possible.
