OK , bit the bullet and bought the car today.
Been researching wheels and the concensus seems to be the ideal size as
18x9.5 with an offset of +38 fitted with 265x35-18 tyres.
Rang Rota today and they recommended not going bigger than 8.5" wide +42 offset on the new model.
Trouble is that I can't find any wheels I like in that sizing.
Don't want to go to the expense of fitting new wheels to have it look under tyred or the other extreme of having a setup that rubs.
Anyone offer recommendations and/or places locally for some wheels
