Yes they have steel wheels in them, however i think there was a small amount of early model 1gs that might have had ceramic wheels. However i have never had seen any proof of this. So most likely you would have steel wheels.
Thanks Fattony,
So what is the highest boost they have been run at? The highest i have seen on here is 17psi.
With a more efficient intercooler..... 20psi?
And what boost level do most people run them at.
I guess its easy to circumvent the boost cut, with either FCD or piggybacks, but has anyone done it?
Cheers
