996 C4S - Uneven tyre wear?

[jjr1]

Is it normal for the inside of the tyres to wear far more than the outer?

Bloody nora were you waiting for that question? Are you psychic?

Ok so if it is normal why is the car setup like that? Can it be changed and what would happen if you did?

Lets see how fast you can answer that one Daz

it's because of the slight negative camber which you need to make tha handling ok for the road.

What would happen if you took the neg camber off? Thats a hypothetical question

Please feel free to nail me for this as my techie knowledge ain't the best but I've been told by someone who 'should' know , that reducing out the camber has the effect of reducing initial oversteer .. Also has the positive knock on of increasing tyre life.

The thoery (and I love a good thoery!!) is that they're set up from factory to provide initial oversteer so that numpties like me will back off before the tail bids me good day...

The 911 thingy has a big bottom slung out back & needs to sort of hang on tight to the road with the inside of its toes to maximise handling potential, release the toes they wear less, but potentially spin more. Of course the inside toes are only part of the equasion, L.S.A. rear sub frames etc help.
Bottom line most Pork does this 4WD, are worse at the front than 2wd!!!!!!!!!!!!!!

Cheers guys a mate with a 996 C4S asked and I had no idea. My C2S just seems to shag its rears very quickly but I think this may be sliding not camber that is the cause

It's simple, wearing the inner edges means you're not cornering hard enough.
