93 Cobra Rear & Wheels on '89GT
 

I finally found and bought a 93 Cobra rear with original disc brakes. I'll be installing the rear this weekend. I have 93 cobra rims that I bought a few months ago, but I'm not going to use them right away. Will I have any problems using my factory GT rims with the additional offset and rear discs on the 93 Cobra rear? Also, has anyone done this conversion? If so what, besides the proportioning valve do you suggest I swap?
