Paul,no 4 spotters Justin?
4 pot callipers wouldn't fit under the 15" SSR mesh wheels we have for the car AND clear the suspension.
Several options were tried and we couldn't get a setup worked out that we were happy with.
Discs that sat inboard enough to clear the wheel fouled the LCA,others that cleared the LCA had the calliper body fouling on the wheel (and we won't run spacers on a road car) and other callipers (i.e. Spoon) bolt up the wrong way around and require too complex a bracket to be a feasible option. Lastly,many disc options are simply not available any more (i.e. Z31).
Many of the bolt-on options for AE86 that are around these days can't be used on this car either,as it runs RA40 Celica front struts.
The PBR two pot Corvette/EL GT Falcon calliper on the car should be plenty anyway,as it's covering a 323x20mm rotor. Pads are easy to get as well.
The setup was done by Race Brakes Sydney at Wetherill park.
