Going to be ordering some 15-20mm spacers I can get the arches rolled or flared that's not the problem I'm wondering about the bumper bracket that sits behind the rear wheel. I'm hoping to go lower at back as the springs that came with my fks are gash and far too high. Wheels are 18x8 et 38 but with above spacer that can be dropped to et 18 with the 20mm and tyres are 225/40/18
