Rear discs from Ssbc. Wilwood adjustable prop. valve in rear line and a disc-disc combination valve.
You might want to keep the adjustable proportioning valve in the rear line if you can't maintain a (front/rear) 60/40 - 70/30 brake bias based on the existing caliper sizes you have, ditch the disc-disc combination valve, as far as the SSBC rear calipers, make sure they are centered on the rotors when installed, most people just bolt the calipers to the brackets, unaware that the caliper must be installed centered on the rotor, the SSBC kits use washers to shim the caliper where it's required, unfortunately SSBC kit install instructions neglect to mention this....
