I'm fitting S4 RX7 calipers to an AE86 (thanks gingernuts) and was hoping someone could recommend some discs that are a good fit in the situation. That would save a lot of hassle.
I have heard that IDB Automotive in Melbourne do a set-up for the AE86 using these calipers. So I would give them a call and see what disks/rotors they recommend.
