For rear brakes we opted for SSBC's A110-11 9-inch big-bearing kit, which we've used on several other project cars with great success. The kit features SSBC's impressive Force 10 Sport R1 billet aluminum caliper with a single 54mm stainless steel piston and built-in parking brake mated to its 11.25-inch vented, slotted, and drilled rotor with zinc coating. We opted for its blackpowder coating as well on our calipers. The A110-11 kit starts at $1,137.95, including all hardware, braided lines, and more. The main axle adapter bracket is attached here, between the axle flange end and the axle retainer bracket, using new hardware from the brake kit.
