would screw directly into the 350Z caliper. Then you could just use the stock caliper bolts and not drill out your spindles. I believe the brembo uses a 12x1.25 bolt hole and the stock z32 caliper bolt hole is 10x1.25..
So bascially the 350Z brembo calipers and 4 10x1.25 helicoils and they're a direct bolt on.
