Inner rear tire wear

[Vivek]

I believe it's the trailing arm bushings, is this wrong? Both the rear tires on the red e30 vert are worn almost identically on the inner 1-2". They're bald there and almost new on the outside.

Is it lowered?

Its a classic case of CAMBERitis.

Like this?



Classic case of sux 2 roll hard.

Get a camber correction kit if you are so worried about it.

They all said it, lowering = negative camber. Camber kit = even tire wear like a vagina.

[Vivek]

Nope, stock springs. Maybe a bit saggy after 130k, but not nearly enough camber to cause that. Looks basically like post 4.

[ÜberslowETA]

maybe crap bushings or blown shocks?

[Vivek]

Here's pics. I believe it's the trailing arm, maybe the subframe bushings. Would this be correct?


Not low at all...

[Vivek]

No one? TAB's?

Worn rtabs can cause that. Have you had the car on an alignment rack and gotten the numbers for rear amber & toe. That will tell if there are problems with the rear alignment.

[hwy84]

Rtabs, not subframe.

Static alignment will probably spec out fine, but the bushings are soft/worn enough that when you put load on the suspension they deflect well past spec and cause the wear you see.

[Vivek]

Awesome, just what I wanted to hear. Gonna do this all the 4th of july week.

as most low/camber guys will tell you, its more toe than camber that'll do that. if bushings are worn then the angles when driving will change causing premature wear.

also to get more life what many people do is keep an eye on them and when they get fairly worn, swap them left to right :)

That won't help though ;)

^You would have to flip them over on the wheel so they roll the same direction on the opposite sides.

EDIT: Only if you do not have tires that are stamped "outside"
