*NOTE: Please be aware that some 1974 and 1975 model year 911s were equipped with Porsche's M-type caliper. If your vehicle is from either of these years, we highly recommend measuring the centre-to-centre distance between the two mounting points on your current caliper or the area where the caliper attaches to the suspension strut. If the measurement is 90mm, this kit is the correct fit. If the measurement is 75mm, please order the BIGBRAKE911REARLY kit, as the brackets in this kit will be too large for your caliper.
