so lets see if i've got this figured out...
stock vx wheels are 18x7 with 38mm (1.5") offset... that means the wheels stick out 1.5" past the hub, and protrude 5.5" into the wheel well
if i were to get steel wheels that are 15x8 with 5" backspacing.. the wheels will stick out 3" past the hub and 5" into the wheel well...
got offered 4 steel wheels for 60 bucks...
