You'll get away with those tyres, I run them on mine - Toyo Proxes TS1's, which have a narrow sidewall giving a tad more space, believe Falken's are good also. But I reckon there's probably not a lot in it, tbh.

I'm on 40mm lowering springs (reckon its nearer 30 thou) and only get some slight rubs on the front arch liners, and a bit at the back when 4 up but rarely when there's two of us.

Got the steering rack centralised then tracked her up, it clears full lock on the 35mm wheel off-set (40mm wheel off-set plus 5mm spacers), so passes the MOT no problem.
