MSW’s Take: Something so simple, but often overlooked. The caliper bolts on these cars are often over-stretched due to removal and install for rotor swaps. We’ve found many that will loosen on track, even when set to the proper torque. A previous owner or shop might have given them one too many ugga duggas with the impact. We highly recommend replacing all caliper mounting bolts before hitting the track.
