C6 to C6/Z06 Corvette Rear RB 4 Piston Caliper Upgrade Package

This is for a previous purchase of RB  rear two-piece stock sized rotors, and you would like to upgrade to 4-piston calipers. This upgrade is good for the following kit part numbers: 2073

    With the purchase of 2, this kit comes with:

    (2) 4-piston aluminum calipers (RB430)
    (2) Aluminum adapters (AD126)
    1 Set of RB ET300 brake pads (PDS110-33)

Requires 18" or larger wheel size. Rotors are Not Included.

Fitment Diagram: Determine if this brake kit will fit your wheels. View diagram.

Note: The required longer brake line is included in our front brake kit as a standard. If you only order the rear kit, you must purchase this brake line kit (P/N BL228ZS-T), because the OE line would be too short for this upgraded brake kit.
