Wilwood Front Red Dynapro Brake Kit with Plain 12.19-Inch Rotors, Listed GM/Ridetech Pin Spindles

This red front package uses plain iron rotors, four-piston dust-boot calipers and dual-pattern aluminum hubs. Choosing the larger rotor does not remove the need to match the specific spindle, bearing journals and wheel profile. Wilwood Engineering is a Camarillo, California manufacturer founded by Bill Wood in 1977. Disc brake design and manufacturing extend across calipers, brake rotors, master cylinders, valves, fittings and brake lines. Parts for street-performance, specialized applications and motorsport must be selected to meet the requirements of the complete brake system.

Check how the wheel rests on the hub before evaluating spoke clearance. Part 300-11961 (sold separately) is the specified 6.60-inch-diameter, 0.20-inch-thick steel spacer for overhanging wheel contact surfaces. The separate 300-10716 hub shield is recommended for stamped steel wheels without overhang and measures 6.15 inches by 0.09 inch.

Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.
