im picking up my 93 gt hatch on the 11th so its time to start learning. this car has the 4 lug setup with drums in the back. can i just slap in a 9" rear in there with discs on it already? basically what i want is a five lug setup on all four corners with a strong rear end and discs all around. where would be a good place to get this from? can i get the 9" rear with 5 lug and disc already setup?
