EBC Racing 12-17 Subaru WRX STI 2.5T Front Titanium Shim

Laser-cut from titanium sheet and perforated to reduce conductive heat transfer, the EBC titanium shims come in sets of four or eight depending on caliper type. Shims are applied to your pad set and can be re-used at pad change unless damaged. EBC Brakes' titanium shims are designed to reduce heat transfer on all types of pads. Most caliper seals are damaged at temperatures over 130degC/270degF, which means anything to reduce heat getting to them is good news.
