This has been spaced 30mm and runs 235.40.17 tyres, on my own car I only spaced them 10mm so it still looked standard



Anti roll bar plays a big part too.
On the H13 (standard 3dr bar) I had no issues but on the H14 (2wd saff bar) I had to trim the bumper and splitter, mind I did put 10mm wheel spacers on to widen the front track too.
Thats with 215.40.17's
