This Carbotech front/rear brake pad set range is for Porsche 986, 987, 981, and 718 Boxster applications from 1997–2020, including base, S, Spyder, GTS, and Boxster T-related fitment where noted. Options vary by CT pad shape, chassis generation, axle position, brake disc material, and compound.
Carbotech offers Porsche brake pad compounds for quiet street-focused use, autocross, and higher-temperature motorsport driving. On Boxster applications, the right pad depends on more than model year alone, so the selected option should match the exact chassis and brake package.
