Looking at wheel options too.... i'm going with an 18" so I can run ~5.5" backspace and not have to worry about tie rod interference. Ideally i'd like 8.5" wide with 5.5" backspace to help run wider tires (keep them a bit further from the firewall).
Ultra Crusher: 18x8.5 with either 5.2" (+10mm) or 5.75" (+25mm) backspace
Fuel Throttle: 18x9 with either 5.5" (+14mm) or 5.75" (+20mm) backspace
