how many piston are the FD front calipers. I think they are 4 piston like the supras, but unsure.
Also what do you guys use for a front skinny when drag racing. What backspacing and size rim clear the calipers.
thanks

 

Four piston.

 

the rear calipers are very low...
I'm not sure of the caliper clearance but they are so low that I think most rims clear the rear brakes without difficulty.

Backspacing is around 7.5" with coilovers.

people have fit 11" rims but had to shim the trailing arms

oops sorry saw that ur asking for fronts.

front backspacing is 7.5" also with coilovers

I think you need around 40mm of caliper clearance

 

what kind of rims do you guys find with that kind of backspacing? What size also for fronts?

 

also can someone please give me dimensions on how long and wide your calipers are. Im trying to see if they will mount on my supra for drag. Our front 4 piston are bulky and no skinny car fit b/c of this.
