This set of OEM Brembo replacement shims is intended to help reduce the inevitable noise generated by the large front rotors of the STI Brembo brakes. 

This set of four stainless steel shims is specially treated with some kind of rubber damping material on one side to absorb noise and vibration.

This set is intended for Subaru four-piston front Brembo calipers only. It will not fit six-piston Brembo calipers.

Set of four shims plus a tube of Brembo brake lube.

Fits all 2015-2017 Subaru WRX STI, plus other Subarus equipped with factory  4-piston Brembo brakes.
