I have a set of Dunlop D02g's that I used in the Ford Saloon Car Championship in 2007 that might do the job, I'm not sure if they are road legal tho??

They are 225 x 45 x 17 and having just had a quick look, two are nearly on the tread bars so there's not much life left in them. I had to use 225's to clear the arch's on my 3dr so they might fit.

I'm in Royston, Herts so if there any good, send me a PM

Regards
Jeff
