Hi,

I am trying to finish off my R32 GTS T/RB30DET, and I am about to put some Big Boy brakes on the front.

My question is - is there a bracket or some way to fit the current 4 Pot front brake set up to replace the 2 Pots on the back...……??

I have seen this once before many years back and thought it was a good cheaper way to get a larger set up on the rear.

'Snot that simple. Rear rotors are only 18-20mm thick (or whatever they are). Front rotors are 30-32mm thick (depending on which front brakes from which car). You can't make the front calipers work on rotors as thin as the rears. So now you need custom rotors, and teh handbrake is in the rotor hub, so that throws another spanner into it.

In reality, the front calipers also have about 3 times too much piston area, if even you put man brakes on the front. The rear brakes are already a bit too aggressive on R32s as is. If you want 4 pots on the rear, then you're going to need calipers with only a little more piston area than the original 2 pots, that will happily sit on the skinny rotor.

Cheers for the feedback. I’m aware it will be a change in rotor change, brake bias, removing hand brake etc.

I know it’s been done on a few track cars and was wanting to know is  if anyone here has done this before and if so what are the specs for the new hats and caliper bracket would be.

Probably easier, cheaper and better to get a set of GTT or GTR rears. I used GTR rears and D2 8 pot fronts and they were adequate to stop my heavy RB30 powered Stagea on the track lap after lap . BM57 M/C and Pagid pads.
