Designed for the E9x 335 & M3, our front brake caliper brass bushings eliminate caliper twisting caused by the rubber guide pin bushings. Precision machined brass guide bushings, and Military grade retaining clips allow your calipers to squeeze evenly on both sides of the brake rotor, resulting in much longer pad life, and more consistent brake pedal feel. Feature heavy-duty rubber dust caps, designed to help protect the guide pin lubricant from dust and debris and to extend interval of guide pin lubrication. 

Guide pins require periodic lubrication.

Included: (4) Brass Guide Bushings, (4) Snap Rings,  (4) Dust Caps. One set required per axle.
