I have a 99 tacoma 4wd. it has the ortiginal wheels(15"x6") on it. i recintly put 31's 0n it.... but wanted to get some new wheels for it... i heard that a 15"x7"/or/8" would work better with the 31's... any advise or ideas?... i also was looking into getting a front end leviling kit... is this a good idea or not?... any good ideas on what kind of wheels or kit to get?... thanx!
