if not mistaken RP01 got 2 models, taiwan & japan made, think. Japan made is pricier & lighter while taiwan's cheaper but heavier bit.
you can use back offset 35-38, width should be 6.5jj also...
if use back stock spring & suspensiong you can easily fit 195/55R15 tyres, enough already
thnx 4 ur info, but i now using GAB suspension, still can use offset 35-38, width 6.5 jj?
can i use 7jj?
