Brass Front Brake Caliper Guide/Slider Pin Bush Kit for BMW 1M E82 & M3 E90 E92 E93 (E9X) - OE Floating Single-Piston Calipers - Guide Sleeve/Bushing Upgrade Repair Set with Clips - Millway Motorsport (Front Axle)

Precision Brass Guide Bush Kit for BMW E82 1 Series M Coupe and BMW M3 E90 E92 E93

Transform front end stopping power and pedal confidence with this Millway Motorsport brass guide bush set for the factory floating front caliper. By replacing the soft rubber sleeves with precision CNC machined brass bushings, the caliper stays aligned to the disc for a firmer, more consistent pedal, stronger initial bite and cleaner pad contact. Ideal for fast road, spirited driving and track days where pedal feel and stability matter.
