rallyR30

I've got a r30 sedan, which I'm, about to fit the rear disc's off the hatch to. I've been told that early 90's 300zx calipers (Twin Spot Opposed, I thinks it the same as r32 rear calipers) will attach to the standard caliper bracket and then 89 model 300zx rear discs (4 stud pattern 290mm, not vented) can be used. BTW. Have you upgraded your fronts and if so what did you use
