If you got 9.5J ET30 all round I think you'd maybe want a spacer on the rear, so getting 10J rears would look best. What offset do the 10J's come in?
Tyres should still fit with a stretch, I plan on stretching my current tyres on my new rims.
Awesome, I'm getting somewhere now haha!
The offsets on the 10j's are et15 et20 and et35
Personally I'd go ET15 on the back then, if not ET20
