G'day Mike
I've got ROH wheels. They're called adrenalin modular. 18x8 fronts and 18x10 rears. I've already got the rubber too - 245/40/18 fronts and 285/35/18 rears Yokohama AVS sport V102. The wheel is a 10 spoke open centre design similar to some BMW wheels but even better IMHO.
The wheel studs appeared to be correct from my measurements but the wheel centre was too small. The rims are beautifully polished and the centres are shadow chrome which will match my paint job fine.
It was a great feeling pushing the baby out of the shed into sunlight for the first time but I'll have to take some pics as the whole suspension needs to be dismantled and reconditioned. I've got most parts and I wanted to do it all before the move but circumstances made me decide to bolt it all together and see how it fits before moving. Turned out to be the right decision.
I was hoping to get up the Heathcote but there was no time. Appart from pics we need times and motor specs if possible. Looks like some respectible times were posted by some bowtie snakes.
