This is the best way to increase the performance of your stock calipers without going for a Big Brake Kit. The kit will eliminate caliper twisting caused by the stock rubber guide pin bushings. The results are very noticeable, even brake pad wear decreases and it provides a more constant braking feeling. Brass is very wear-resistant and therefore ideally suited for this part.
Manufactured in-house with extremely precise tolerances for optimal fit and function.
Fits all BMW factory ATE brake calipers (front and/or rear) (E81-E88, E30-F30, E28-F18, E24-F13, E23-F04, E31, E53-F15, Z1 Z3 E52-E89 ). To be sure, check for ATE on the sliding claw. (or check with the BMW part no)
