Pete,
I had 18 x8's all around on mine.
Front wheel offset was 35 with 225 35 18
Rear wheel offset was 30 with 245 35 18
Tires were Toyos T1s. Avo coilovers. Front had a bit of the angle grinder
the rears were untouched fit fine. Everyonce in a while they would rub on a hard bump but other than that they were fine.
My tuner mate has (or had) 275 on the back of his.
