Abnormal tire wear

PayamFSU · 08-07-2020, 07:56 PM

Is this from the -2.2 camber ? Or from the toe being a bit off ?

This was 10,000 miles on this alignment .....

Ok, white line on the inside.
You are rubbing on a strut or something.

Do you have camber plates or just have the camber adjusted to that negative level?

Camber plates , stock struts , just lowering spring .8". It's not rubbing there is no rubber on any component of the suspension. Also have 12mm spacers.....

What springs, or are you height adjustable?
I ran Swift and Eibach Springs on my 2105 M4.
Also added TC Kline camber plates.

Based on the wear pattern, I have to assume this isn’t from track driving.

What are your toe settings? Bad toe will increase scrub and is a likely culprit.

Spacers also do not help as they alter the scrub radius and the required Ackerman angle when the wheels are steered.

Probably toe out, did you just increase camber with your camber plates and just not re-adjust your toe? This platform will increase toe out severely for the fronts when you increase camber.

I'll have to find the print out but thought we brought the toe back to stock , camber was only -2.2 in the front ...... no I have a second set of wheels for the track this was only for street use , rears wore well with -1.8 camber

You're 100% rubbing on something.

-2.2 camber won't do that. Toe-in might do that but that looks very concentrated.

That’s not from rubbing, that’s from scrubbing
