Too much camber

[Dezzy]

Heavy tyre wear seems to be because I have too much camber on the front wheels. Toe is out too but it’s cancelling out some of the affect of having too much camber so it has been left unadjusted or my tyre wear will get worse. Matey went under the front and pushed up taking a bit of weight of the suspension and the camber comes right, or within tolerance anyway.

So I suppose the questions are do the springs get weak and lower the ride height, or has it been lowered at some point? (I know you can’t answer that) But can ii count the coils on the spring? How many does a sport spring have?

The 8 isn’t a sport but does have sport suspension as an option from new so it might have bits replaced over the years with wrong parts maybe? Strange really because the front looks higher than the rear. If I jack it up so the camber is right it’ll look like I’m permanently going up hill.

My printer doesn't have any ink and that means it won't scan or copy ah the joy. So job sheet with the reading will follow when i get home at the wk-end maybe someone on here can make a bit more sence of it.

You can't adjust camber but you can center it. If it is out by different amounts on each wheel you need to center the subframe. The process for that is here. The specs are here.

Thanks for that Mike, i will get the result sheet uploaded so it can be viewed by all.

I know the camber can't be adjusted but the ride hight of the car makes a differance to it, so if my 8 has been lowered via shorter springs this would make my camber worse. As the car is jacked up the camber comes right.

I know it's low because i have to drive on to a board before i can get my trolly jack under it.

Anyone want to measure the hight of their car so we can compare?
To get a level playing field measure from the underside of the jacking point to ground. I know it's not the most scientific way of measuring but hey ho.

Who has the lowest 8?

Really my A should sit higher than an S?

this company,http://www.k-mac.com.au/ , makes camber adjustment, replacement bushings with eccentric bolts for a8/s8 upper control arms, however they are difficult to set up.

Thanks for that
I like the look of those adjustable top arms, they look sweet.

The thing is, if it's not adjustable with out these bits and bobs how come i have too much already, it couldn't have been like it from new. So i shouldn't need to buy adjustable stuff to bring it back to standard settings.

since i bought my one owner s8 7 years ago, i gone through many sets of front tires and 3 different alignment specialists, tyres still always wearing on the inside edge, so i suspect bent control arms. after all they are alloy. anyway, too much negative camber is suposed to be good for cornering.

I replaced all my arms a while ago so not them.



Maybe i shold start saloon car racing
