Hi all,
Looking for some new wheels for an 02 STi with Tein SS Coilovers and have found a set of 18x9.5 +35 Rota Grids with 235/40/18 rubber.

Ideally I was after some 18x8/8.5 +40/42, what I would like to know is how well & how easily would the Grids fit and how negatively would this affect performance?

Any help and/or opinions appreciated,
Thanks.
