Alright I'll look into the camber bushings within the next two or so weeks.Might as well cut your testicle off yourself. You don't want to even know what happens to it when your camber goes over 2.
In all seriousness, I have always read over 2 is no bueno. This could be because is a nice round number, but 2.4 seems to be a bit much.
So my next question would be, when I get them installed should I have them adjusted to be completely even say -1.0 on both sides seeing as the offsets will do a maximum of 1.5 correction?It will probably save you a lot of money in tires in the long run if they were unable to get the right rear to -2 or less. I finally had to do adjustables in my BMW after going through rear tires every 4 months with -2.8 and -3. I currently have it set at -1.5 and I have even wear on the rears.
This is the general consensusnumerous other threads about side hop and targeting 0 toe and total toe to reduce/eliminate it.
You realize this is a FWD bias AWD car and the BMW is RWD right? Negative one degree of camber should be plenty. Most race cars have more negative camber in the front anyway, but that's horrible for every day driving. Honestly I would say save the money for other stuff. If you get a set of tires with a harder compound, rotate them and keep the alignment as far as toe in spec you should be fine. Your toe is what will cause most wear anyway.I would definitely want them even. I tried -1 on my BMW rear and found that the handling wasn't as good. I feel -1.5 is the best setting for handling and tire wear.
