Does anyone have a definite answer to this? I have just tried to fit GTA wheels to my 2001 GTV V6. I've got some 6mm spacers too so that should compensate for the different ET. My GTV bolts measure 32mm (even though the box for the locking wheel nut says L=36). I screwed in the 32mm bolts to the hub and compared how far the bolt stood out compared to the protrusion of the bolt through the wheel and spacer. It looked about the same so I gave it a go. It seemed to tighten up ok, but then there was a groaning noise as I moved the car, so the bolts are just too long.
I want as secure a fitting as possible so am not keen to use 24mm supplied with the GTA wheels, not least as they are horrifically rusted. I guess I need 28mm but can anyone confirm?
Also, what are the bolts actually sticking into behind the hubs?
Finally, where can I buy the correct fitting of bolts from?
