Rear suspension geometry

[barefootoo]

Can any one help!" Have just changed my shocks all round for Gaz coilovers. Nice product easy job, but on lowering back onto the deck have noticed that the rear nearside wheel has about 3%+ (have not measured exactly yet) more camber angle than the offside one. Cant see why! I have checked both units and they are set up the same. Thing is I dont remember ever seeing this problem before change over. Have even measured the chasis height off the ground both sides and they within 1mm
Thanks in advance

How are you gauging the camber? If you're just standing back and looking at the wheel, you're probably being thrown out by the bodywork overhanging the tyre by a different amount on each side because it isn't symmetrical. I suggest you find some flat level ground (use a spirit level - Mk I eyeball isn't good enough for this) and then measure the camber on both sides. You only need a ruler and plumb line, nothing fancy or expensive needed.

I found the same thing having fitted new trailing arms this winter (the 2 piece ones).

LHS camber 1,1° RHS camber 0,5°

Going to have to make some shims I reckon.

Gerald, you are a gent. never new this link existed. Have checked the camber angle useing an extra large square and its definatly wrong probably about 2.5% enough to notice ( well me at least ) On a realy good inspection it looks like, and in fact im sure, the trailing arm has been replaced. Hmm, not sure how to get around this one except perhaps in the winter to take it off, rejig the mounting plate on the inboard side by redrilling the holes and welding a new faceplate on. But this means that the outboard bush may need refitting as it may then be to far out of allignment. Have checked the chassis allignment and it is now within 1mm across the rear chassis, so guess thats not the problem. Glad I took early retirment as I would never have had time to own my treasured S

If you have too much -ve camber on both sides, suspect the ride height is too low. If it differs from side to side make absolutely certain you're on flat level ground before you go any further - it needs to be flat to 1/4" or better and you have to measure it, it's impossible to judge by eye.

If you do need to correct the camber check the condition of the trailing arms. They weaken with age and corrosion and the geometry problems might just be the first sign that it's starting to give way. If you're certain the arms are sound, check the bushes. If they're OK too, you can adjust the camber by shimming between the hub and the trailing arm. Or you can just get used to the fact that your car has really sporty racy suspension settings and go drive it more.

your right, just going to drive my beloved Trev untill the winter. On the + side it will narf go rouund R/H bends well.
