yep i know ..... lots a money. My advice would be take your time modding as you only wanna do it once, look at heaps of different set ups and see what u like best. Don't just buy the ARB booklet.
Don't know laws in Qld but in W.A your only allowed 2inches pfft. My Tyre's are 3 inch bigger then stock
.... I figure, i don't drive like a clown on the road, they are NEW cars ( well mine is newish) and if you don't draw bad attention to u're self you'll be ok..
Or if your gonna go all out spend the extra and get it all engineer approved
Good luck !
