In preparation for getting my Astra H Penta 18"s on the Gsi I'm looking to get it lowered. The offset of the wheels are 37 I believe so I don't really think I could get away with much lower without scrubbing, even with 215/35/18's. I really don't fancy the idea of getting my arches rolled - had it on my old nova and the paint cracked. Bearing in mind that the gsi is supposedly lower anyway do you think it would be worth lowering it 30mm ?
Cheers for the advice as always
