Product Description

The EBC S4KF1339 brake kit is a front-axle performance upgrade designed for BMW E9x 3-Series models including the 335i, 335xi, 335d, and 335is. It combines EBC USR slotted rotors with Redstuff ceramic pads to deliver improved braking performance, reduced brake dust, and better heat management compared to OEM braking systems.

A Geomet coating provides long-term corrosion resistance in all climates.
