about wheels..

[Dan]

I'll hopefully have a bit of cash together by this summer and im looking to upgrade my s12.. apart from an intercooler setup and boost valve and gauge i was looking to get some new wheels (my originals are quite corroded and a little damaged from an intimate moment with a curb)..

What im wondering is, what size do people usually go for, is it possible to get slightly wider rims to fit wider tyres? lower profile too. 7 spokes are preferred.. how much would i be looking at?

Thanks!
