I installed Swift lowering springs and e46 m3 zcp wheels w/mss in May (tires were almost new). I had the car realigned immediately after. Today I noticed that I have very bad inside tread wear on my rear passenger tire. I also noticed that the front passenger is also starting to wear on the inside edge. I stopped by the shop that completed the alignment and they said I most likely hit a pothole that threw the alignment out. I'm skeptical of that.

Based on the results below, would these alignment specs cause edge wear like this? I've owned a few e46 m3s and I'm familiar with camber wear from back rtabs but I was unaware that e92 suffer from a similar problem. All the suspension parts are tight even though I'm at ~90k.

I'm gonna have this shop check the alignment again but I don't want to put on new tires and go through the same thing in 3 months.

Here's before and after. They weren't a performance shop, so no camber adjustments on the coil overs. I'm very low but it's strange that the rear left camber is at -3.4*. Assuming that negative camber is contributing to my car pulling slightly to the left on the road. Thoughts?

New member here on the forums. I'm taking my car in this week to be realigned and I was thinking about doing -1.5 degrees of camber all the way around and maybe .05 degrees of toe in for the rear. Any input on this setup? The car feels pretty loose in the rear even though I put a new set of Michelin PSS on the rear.

Currently running:
KW Sleeves (1.2in drop in the front and 1.0in in the rear) with 12mm MS spacers all around. Wheels and tires are OEM ZCP specs.

Thanks for the help!

Bad idea in my opinion. You need .10 degrees of toe on each side on the rear for stability under braking and acceleration. Less than that, especially a total toe of 0.05 degrees, and you'll have instability.

You can run zero toe up front if you feel the need to run a lower toe setting somewhere on the car. It'll be more darty at the front, but it's a whole lot easier to control a front end that's darty than the rear. Also, set your camber up front at least 1/2 degree more (negative) than the rear.

If you aren't tracking the car, just run it in the stock alignment range.

Thanks for the feedback! Good thing I posted the specs before I took the car in.

I had the guide pins pulled on my E92 ZCP today and the alignment came out like this:

F Camber -1.5/-1.5
Caster 7.0/6.9
Toe -0.05/-0.05

R Camber -1.9/-1.9
Toe 0.11/0.11

The car is driven a couple times a week and tracked five or six times a year. If I went to a camber plate system to get -2.0 camber up front would it make a significant difference at the track? Are there any camber plates on the market that don't raise ride height?

Iím on 255/35/19 and 275/35/19 AD08R tires.
