here are the results from the setup (both tyres currently wear out the same on the inside 2 inches):
Rear Camber: L-2.5deg,R-2.0deg
Rear Toe: L0.2deg,R0.25deg
Front Camber: L-2.4deg,R-2.4deg
Front Toe: L0.1deg,R0.1deg
Front Caster: L5.6deg,R6.1deg
In fact the fronts wear too on the inside but not so bad.
IS the camber too near the limit of R-2.5deg and F-2.4deg?
Can it be adjusted by me?

oooh thats not right, for a start front camber should be 1.10 both sides and at least .50 of a degree to much on the back. Rear toe should be 0.10 degrees.

Two thingmto bear in mind with all this. If your tyres wear badly and the car is re set up to correct the wear, the wear wont dissapear until new tyres are fitted.

Secondly the rear only has one adjustment which affects toe and camber at the same time, so if the rear track rod adjuster is  seized both will be out.

Those numbers look like somebody has just gone to factory settings which are far too wide a tolerance.

Suggest a trip to wheels in motion in Chesam, they know the omega and how to set it to tired old suspension. :y

yes its possible to adjust diy, but impossible to do accurately to the point you can trust it not to ruin expensive tyres.

You could take it back and complain...?

ok to reduce camber should i shorten the track rod? I intend to remove them, free them up and replace.

mine needs freeing off as well on the pass side, and i've no idea which way to turn it, there's no way of telling how accurate the setting is without meassuring on a lazer rig such as wims hawk eye .

Those settings are appallingly bad :o - you will knacker the front tyres quickly as well.


With the rear, its a compromise between camber are toe.  If you cannot get a good compromise, its likely something is bent at the back...

Can anybody give  settings what would be at least near correct.
I would gladly go to WIM but it is several thousand miles away  ;D
The garage here that does those probably has no idea what they aare doing!
I did get it done but obviously it is wrong

So if something is worn causing excessive camber at the rear, what could it be?
I have adjusted one tie bar right up, not much thread left but still the wheel looks excessively cambered!
Any ideas appreciated.... :(

As already said - Tony @ WIM Wheels in Motion.
Maybe a bit of a trip but worth every penny  :y
Give him a 'ring' with your 'readings', ask what he thinks.

Per chance is it being adjusted the wrong way?

And yes it is worth checking the springs are not broken off at the ends.

But FFS get it set up correctly or you'll be throwing tyres at it forever.

Not the thread starter but mathewst from Croatia asked for information where it appeared you were directing them to a WIM centre in UK, you actually were not ... a bit of a trip that would have been from a guy in Croatia  ;)

hmmm it looks logical from under the car that as the adjuster gets shorter, camber should reduce.
But I haven't tried the other direction. As soon as it stops being very hot, I will get under the car and give it a go. :P

OP might have got something wrong: adjusting/turning tie rods will not affect camber, it adjusts toe. Camber is adjusted by opening the bolt/s on the strut...

I might be at the wrong end of the car though....  :-[ :-X

think he's talking about the pass side rear?
Title: Re: Rear Suspension - inner tyre wear - solution?
Post by: feeutfo on 05 July 2010, 09:41:36
maybe use the opposite side thread length and wheel angle as a guide?
