i reckon 10j offset +40 on the backs is the widest and lowest offset you could run on standard arches. Maybe 8.5j et 40 on the front.

Sorry for the hijack, but any idea what the \'j\' stands for?

A good thread on wheel sizes...

It seems as though 18x9 are used on the fronts understandard arches but are these rolled?

I have 9.5j on the rears and 8.5j on the front both at 38 offset and this is tight !! Level pretty much with the arches, think you\'d have to do something with the arches if you went any wider or had different offset...

At the minute im running 10.5x19s and 9.5x19 racing harts but i cant lower the car so i thought i could come down to the same widths on 18s but i dont know what the best offsets are.I want to run at least a 110mm dish on them.
