Hello Zoners,

In abit of a dilemma, Ive seen some split rims which are 8.5J with an ET13, The lip on them are 2".

What I wanted to know is......would these fit? (im assuming so) Also I want to change the lips on the back alloys to a staggerd setup...prefably 3.5/4" lip - Would these fit? How far can I go without rolling the arches?

Thanks for any help.

8.5j with ET13 will fit with a 205 tyre you may 'just' get away with 215, if you add 2" to the lip it will make it a 10.5j with an ET of around -13 = fail

iirc for every inch you add to the outer lip you take 13mm off the ET.

Rav will know :D
