Product Questions


On the picture it shows 2 types of rotors. When I choose the black power coat ones it shows the standard rotors, but I want the rotors with the slots and holes. How do I specify I a want the the rotors with the holes and slots?

Unfortunately, this kit isn't available with slotted/drilled rotors. The picture is incorrect and we're going to be working with our photography department to get it fixed. Thanks for bringing it to our attention.

what about the proportional valve, will that need to be replace for a 1994 proportional valve for disk brakes. I have a 1992 proportional valve that leaks and no luck finding one that fits a 5.0 mustang with rear drums brakes.

Asked by: santocache
We have several available. The SSBC version is CJ part # A0707-V and fits all Mustangs from 1964.5-2014.

Looking at the parts listed in the Kit Features and looking at the pics...there is no master cylinder in any of the pics. Is this just an oversight? What part# master cylinder should have been included?

Asked by: CarCigarGuitar
A master cylinder is included. It just was left out of the photo for some reason.
