I have one brand new Bear Serious Street rear brake package available. This is part number 4302019. It comes with 11.35" rotors and 1 piston calipers. It fits 1967 Camaro/TransAm and 1955-''57 Chevrolet passenger cars. This system retails for close to $1000. but I'm able to let it go for $500. A customer didn't need it so he asked what I could do.
