Yeah the gtr wheels stick out further than gtst ones but they're also 2 inches wider (8 inch) so they protrude further towards the suspension as well. I've only got a finger space between the rims and the standard shocks at the moment so if the BC's are much larger than stock there may be problems. But like you've told me before I may be able to get away with it by running more camber to pull the shocks in a bit.
Guess I'll just have to take a punt. If it works, good. If not, it'll be a good excuse to get new wheels
