I'm running weld EVO's 17x8 front and 17x9.5 rear on my car with 245/45R17's front and 305/45R17's rear. The front wheels are 5.7" backspace and the rear is 5.9", Super Stock springs with 1" offset hangers, 3" (yikes!) lowering blocks, longer studs and 3/4" inch wheel spacers (rear only). The rear outer wheel well lips were cut (would be better to roll them). Would have liked to have a different offset, but choices were limited when I bought the wheels. I have a set of ET Streets for the track, 28x11.5 on 15x8 centerlines with 4.5" back spacing, no spacers. Last pic is a 275/40/17 on another 17x9 with 5.9" offset, I think it looks small but that is just me.
