The Wilwood NDPR radial front drag kit uses forged billet radial-mount four-piston calipers and specialized brackets that bolt to the OE mount, addressing fitment into popular 15" drag wheels. Recommended rotor thickness depends on vehicle weight and use: 3/8" steel rotors for cars up to 2,800 lb and .81" rotors for heavier or extreme-speed applications to improve rotor durability under demanding conditions.
