I did the 11" upgrade from K-Tuned with drilled rotors and it went great. Now I'm turing my attention to the rears. I was searched for rear brake upgrade and just found stuff for 1.6. Anything for junk yard bolt-ups off the rear of RX7 maybe?
Thanx for the help.

I think I found my answer, thanks Bob (bbundy)


I will say that putting on sport brake calipers in the rear made a fairly dramatic improvement. Even with my 11.44” rear rotors before going from the 1.25” piston stock rear calipers to the 1.375” piston stock Sport brake calipers I always had the Wilwood Bias valve set full rear. The larger piston rear calipers gave me some adjustment range to where I could just get it to the really sketchy point on rear bias and the whole braking system felt more responsive. If your running just the 9.88” stock 1.8 rear brakes with the smaller pistons there is no way you will get the bias right. I think minimum you need the 10.84” sport rear brakes with this setup, really any of the wilwood front kits available you need a minimum of the sport rears.

See, it does pay off to read all this stuff instead if spending time with your family.
