Tweed.. I'm running 16x9 et 15 out back with 2deg camber and I've pulled and rolled my arches as much as possible with out cutting inners. I'm down quite low, running 205/40's with no scrub...
Had a few goes as gone lower so needed to pull arches more etc... Arches are quite put of line to how they was, but the bit your interested in is the arch trims do go back on. Tiger seal and sh!t loads of clamps. Think I used 8-10 on each arch and left to set for 24hrs plus!
That's what I've found best method anyway!
Fronts are 16x7.5 et 17 and just rolled the lip and boshed 1.5deg camber on there. S'all good.
Hope this helps.
