Question about brakes / rims

[james-adl]

Howdy guys,

Just wondering how big a rim I'll need to fit 330mm front discs?

I'm guessing 19s but would rather pay for 18 inch tyres

Cheers

All Holden and HSV 17's and 18"s will fit over either of the 330mm disc and calipers setups that were available from VR-VZ.
A lot of aftermarket 17's and even some aftermarket 18"s won't fit over.
I have 350mm front discs and my yellow spare is a HSV 18" wheel/tyre which fits easily.
The biggest VT wheel available back then was an 18 on the GTS300 and that fitted over Harrop 4 piston calipers and 343 discs.

i upgraded to 330mm rotors on my vz. the 17's which are standard on a sv6 fitted but there wasnt much clearance.

On my old VL I had VN GrpA 330 discs and calipers under 16" Walkinshaw rims and there was less than 3mm clearence but never had a problem, just make sure you dont use stick on weights in the area covered by the caliper.
