my tyres are wearing unevenly, the inside edge on both sides is wearing quite quick.....
i'm sure I read somewhere that camber doesn't cause uneven wear, but tracking will. Is this true?
I'm running 1.5° negative camber (track car), and I thought zero toe, but I set it up myself with vaguely the fishing line method so not 100% sure on the toe.
just for fun heres a couple of completely unrelated pics, first few of recent mods to the red golf ready for cadwell on saturday, the others just a few I took recently
That's not -1.5 degrees of camber; it's more like -4! I'd check if I was you.
Tyres will probably wear quickly at that angle.
The general concept behind toe settings is that the wheels are pushed / pulled back to parallel under drive forces when driving (ie against the flex of the bushes). And there's a bit extra added for the sake of steering feel etc.
Different cars need different settings according to their suspension design, so it's not as simple as 'all fwd need toe-out' etc.
If you modify the suspension by lowering or stiffer bushes then the manufacturer's settings become irrelevant and you have to start guessing. Most people just go for parallel in this circumstance as you suggested.
There's all sorts of ways you could measure the toe, and the fishing line / Cornflake packet / clothes peg and banana method should be ok as long as you do it carefully.
If you get a garage to do it you need to watch what they're doing, otherwise you'll just get "car's bent mate, innit?".
For you I'd probably do:
>>>Re-measure the camber and toe.
>>>If you do have much more than -1.5 then perhaps think of making it easily adjustable so that you can run extreme camber on the track (and live with the tyre wear) but something more sensible on the road. Remember that changing the camber will also change the toe.
>>>Check that something else isn't wrong, such as knackered lower arm bushes.
If you do actually have a lot of camber you might be better off running abnormal tyre pressures. I don't know what to suggest but you'll be able to google something.
