I have a 94 Caprice 9c1 lowrider that I am attempting to put 14x7 reversed Supreme wheels on, but I'm going to have to use a spacer for the front to clear the brake calipers. My question is how big are the rear calipers, as I have been told that rear disk brakes were standard with the 9c1 package? Will I need a spacer on the back? It currently has 14x7 reversed wire wheels on the back

 

I found one source that said 94 9c1 had 4 wheel ABS disc on front and drums on back
