r34: a member of this forum made some nice offset wheels that you might be interested in checking out
also i think that rs should make some metal wheels cause these plastic ones are so easy to tear up and mess up... i have a whole set of wobbly wheels...
3 of them gtr's, dunno why but they tend to get messed up easier vs the other wheels. (notice that the gtr wheels are made of different plastic and not painted)
on xmodworld.com they are selling some alloy wheels but the price is way too steep for me...
