2nd Gen Mini Tub Backspacing?

[glassman]

I did 6 3/4 with an 18 x 12, running a 315...butttttt, mine can come out at least an inchtoo narrow. I believe u can use this sizing cause mine can come out a lot more, HOWEVER, the TA's can withstand a wider overall (track width).

Best bet is too buy your rims FIRST, get close to the size, mock up, then build your reared to suit
