Merv,

I'm not a Holden (or Ford) guy so please don't take my comments as gospel.

I believe the HSV calipers/discs will fit but you will need to check. I assume you're running the Skyline rears so the brake balance may change.

I'm using AP's fore and aft with the radial mounts and 330mm discs. This is the setup used for V8 Ute series and fit VT to VZ series Commodores. I looked at going to a larger disc but it was a whole lot of pain and expense for very little gain given the weight of the car. My car has the fabricated IRS which uses Holden bits, so for me it was a simpler decision.

Give Matthew Pearce a call at Race Brakes 02 9609 1101. Sound him out about your options, he was pretty good to do business with.

Cheers
