would you be able to recommend some settings (toe and camber)? then I can just go to the garage and tell them what I need. what did you do on yours? my bro said -1.5 may be ok?
Tbh i would not know, what the settings were. It was about 2-3 years ago, when i got mine done and i told the guy, do what you have to do, but it should not catch in the arch.
But what i can tell you is, First he aligned the rear wheels to factory settings, then he moved on to the front wheels, aligning them with the rear's.
Then he sorted out the camber/caster on the front, so it done touch. and when the car was on the ground, i could tell that the front wheels were at a slant and it looked ace.
also, some people place the clamp on the alloy wheel itself, and some place it over the tyre, which in your case if your car is low,the clamp will not go over the tyre, due to the arch being in way. so you would have to source someone who places it over the alloys.
