Rear camber is eating up my tires!!

[e28jay]

Hey Guys,

I just purchased this car about 6 months ago. Now the previous owner did tell me that since the car sits so low, it shreds the inner tire in about 10k miles. What is the best way to correct this? Will going to a 15in wheel help this? Right now I am running 16x7.5 with 205/45/16. The suspension is Eiback springs with Boge turbo.

How about camber plates?

the best way to correct it is with rear camber plates...

camber plates will do the trick most likely. my car has camber plates on it and my tires seem to be holding up just fine.

There is no such thing as camber plates for the rear on e30's.

You can bend the rear trailing arms or get offset trailing arm bushings to try and correct some of the rear camber.

yeah mine only has plates on the front. my car isnt so uber low that it needs anything done to the rear though.

Try get a print out of your rear suspension settings. That should point where the REAL problem is. Camber alone is not to blame; toe & worn susp components also contribute to excessive wear.

This topic comes up a lot, you have 3 choices:

One: Live with it. You don't have coilovers, so your car can't be that low and it could be a lot worse.

Two: You can buy some adjustable trailing arm bushings that will dial out about 1 degree of the camber. I believe there are two different kinds now.

here's the newer ones...

and the traditional Kmacs (however, some report that these fall out of position)...

Three (the correct way): Buy some adjustable camber mounts, but this is much more involved and requires modification to the rear subframe.

It's the toe settings that is really eating your tires, not so much the camber. If you want to run an adjustable toe (or camber) setup in the rear, you have a few options.

1) K-Mac adjustable trailing arm bushings
2) Ireland Engineering (or something similar) adjustable trailing arm pickup mounts.

If you don't want to spend money, just throw in a different set of rear springs that will let the car sit higher and have less of that tire-eating toe and camber. If you do want to spend $$, I'd go with option 2. 8)

You could also stack spring pads in the rear in order to raise the rear and lower the camber.

oops, thats' what i meant :oops:

well, i dont know all that much about correcting camber just yet...but i do know that your tires are undersized. if your runing a 205 on a 16in rim it should be a 50series not a 40 series.

True story.

Thanks for all the great advice. I'll have to check out some of these options. IE parts seems like the way I will go.

The tire size is actually 205/45s, still undersized?

[Digitalwave]

Yeah, proper 16" sizing is 205/50 or 225/45.
