Correct Offset

[AshRX]

I have seen a set of 18\'s i like which are the following:

Front 9J +20 Offset 18"

Rear 10J + Offset 18"

Will these fit ok on standard archs

Im running Tein Mono Flex Coilovers

Cheers

i dont think they wil fit under standard arches. ET20 is too low

[AshRX]

missed a bit...

18 inch

9JJ wide

+20 offset for 5H


18 inch

10JJ wide

+30 offset for 5H

I had +18 on 18x9" fronts and +22 on a 18x10" rears and they were out by nearly an inch front and back!

[AshRX]

could of got them for a really good price too

You could always roll the arches?

Stock offset is +50 all round with an 8J 16. From there, use an offset calc like the one above or the one on driftworx.com.

Mine have 38 offset front and rear. front 17x8 rear 17x9 no problems with fit or rubbing antwhere,

I have 18x10 38 on the rear, lowered a little, with rolled arches - and I can still get them to rub just about if I *really* try...
