can anyone help i have a carcked rear brake disc on my 96 n/a supra. when i bought the car i was told they are the big turbo brakes but when looking for a replacement pair of discs i am unable to find any the same dimensions. the ones that are fited are drilled and grooved and are 318mm diameter, the ones i have seen forsale are all either 307mm or 322mm i dont think i have enough clearance on my caliper to fit the 322mm discs.
