Wilwood makes brakes for race and street cars, and they continuously bring innovations to their product line. At the 2012 SEMA show, Mike Hamrick brought us up to speed on their new large diameter 1-piece rotor systems and tells us about the importance of choosing the right parts. These new kits feature radially mounted calipers for multiple adjustments, 1-piece rotors for cost savings, and a new forged caliper design with internal crossovers for strength.
