Supra since '86
The only way to use the Z32 discs is to do a lot of machining on the hub and to fabricate a 10mm thick bracket. Yes the Z32 disc has the perfect diameter and width dimensions, but the hat height is too high. I don't really like the idea of machining material away from parts unless there is no alternative. Why weaken anything.Why do you need pad spacers if you are using a Z32 Caliper on a Z32 rotor? I dont get it!
I think there is a better solution than what the Japanese guys did, I thought of using the Z32 calipers before I even knew anyone had already done it. No Toyota 4 piston calipers would fit the stock MK2 strut caliper mount so my next step was to go to Nissan... then Suburu etc.
My idea unfortunately involves a disc width that is some what narrower than the stock Z32 disc, I could not find a suitable wider disc. In order to use a narrower disc it would be safer to use the shims. If the pads wear too much with out the shims the pistons may pop out. A bad thing.
