        Wilwood Rear Big Brake Kit

        These are totally awesome. The look completes my SC281 Saleen wheel set up! I will admit that I had to get the steel braided brake lines and the parking brake cable set up from Wilwood to get the correct finish. They did not come with the kit!

        Great looking brakes

        Bought these to go with my 14" Wilwood brakes up front and they look far better than the wimpy factory brakes! Word of caution, you NEED the wilwood parking brake kit which AM no longer carries. Without it you'll need to have the factory lines modified to work.

        95 mustang gt brake job.

        The brake kit did not fit my FR500 10.5" rear wheels , no clearance. Would be ok on the FR500 9.5" wheels because of a different offset.

        Good Product

        For those interested in buying these rear brakes, i STRONGLY RECOMMEND you order the brake lines from wilwood yourself. The OEM brakes lines did not fit. At least they didn't in my convertible.

        Awesome Brakes!

        These are a fantastic brake kit you can ever buy. Not only do they look sweet they can stop on a dime. Had a lot of fun breaking these in. Amazing braking power.

      5 Top Rated Questions

      other: Hi...I have a 95 GT with Power Slot rotors and Hawk HPS pads. My parking brake is still very weak, even after my friend installed a hydraulic ebrake that used the assembly I had. If I were to purchase this kit, would there be enough power to lock up the rear wheels as in drifting? Also, is AM going to have dual piston rear calipers in the future? Keep up the good service AM! Justin

      • The Wilwood Rear Brake Kit should be enough to lock up the rear brakes. Typically, it can be difficult to lock up the rear brakes because the cable is stretched out, and the parking brake lever does not have enough leverage. With a hydraulic e-brake and the increased diameter on these rotors, they should lock-up pretty well. If the e-brake level is a vertical unit, the fluid will compress the caliper with much less effort by pulling the e-brake.

      Does this kit work with the 17 X 10.5 Bullitt style wheels?

      • No, this kit, nor will any big brake kit, work with our Bullitt style wheels.

      With this rear brake kit can you still run 15in wheels? Thanks

      • Hey Robert, With this brake kit it will require the use of 17" wheels or larger, it will not fit 15"

      The front super-lite rotor/caliper kits require Wilwood flexline kits to replace the OEM lines. Does this rear caliper kit require something similar?

      • The only other part you will need is the Wilwood Parking Brake Cable Kit (94-04 All), item # 48309, ( This is because the OE parking cables do not adapt properly to the Wilwood Calipers.

      I am looking to upgrade my rear brakes on my 01 cobra. I am wondering why this product is not compatible with the cobras, does it have something to do with the IRS?

      • The Cobra, Billitt, and Mach 1 Mustangs have different brakes than the V6 and GT. This brake kit is designed to be an upgrade for the GT and V6 Mustangs.
