impact on tyre wear of track settings
Discussion
Track settings (mainly camber) basically mean the tyres are set up to give maximum grip i.e maximum area, when the car is under cornering load. This means that when the car is not under load, under normal driving conditions, the tyres are not likely to be giving their maximum footprint. Therefore, you will get uneven wear. You should also note that because they are not in full contact with the road when under light or moderate cornering forces, wet weather grip (where the forces are much lower) can diminish compared to normal 'road' settings.
I know of a 968CS that got written off at the ring in the wet just a few miles after having the camber changed... do track settings if you drive it hard in the dry. If you don't drive hard or drive in wet weather, I'd think carefully about it. You could end up with less grip.
Also it's worth remembering that factory standard settings are often very good. The cars didn't spend ages under test and development by people like Walter Rohrl just so owners could wind on a bit of extra castor or camber when they felt like going quickly

Specialists (such as Parr Motorsport/JZM) have 3 settings to address this very issue....
Track - Aggressive camber for full on track use. Will see heavy inside edge wear when used on the road.
Road/track - setting for a bit of both. Will also see wear on the inside edge but not as bad.
Road - just wot it says on the tin.
Take your pick depending on your intended use.

Be aware , track settings, exactly as Domster says will wear the inside edge of ur rear tyres under road miles for exactly the reasons he says .............i did nt believe it when mine were thru to the canavas and the rest of the tyres like new .............had been commuting in GT2 ...............wasted tyres !Bloody lethal cos they re quite hard to see, usually warning as they deform , if unlucky just blow to bits when u least expect on a track day , ask Russell abt Eau Rouge .........there is a happy medium !
I run a GT3 with an 80/20 track / road set up - ie, quite a lot of camber front and rear (Manthey settings).
With track tyres - such as Dunlop SSR or currently Pirelli Corsa - the inside edge will wear due to road use - eg, driving to and from a circuit. For me, it is not unusual for the outside edge to still have 3-4mm whilst the very inside edge is near to canvass. This is far more prevalent on the rear tyres for obvious reasons.
The effect can be minimised by ensuring that road pressures are set above normal road pressures - Manthey recommend 2.5 bar front, 2.8 bar rear cold (cf 2.2 and 2.7 respectively per OEM). Driving even a few miles with track pressures (ie a lot lower) will rapidly wear the inside edge.
Despite this, I still get a good life from the tyres - up to 3 - 4,000 miles from my rear tyres and nearly 5,000 from the front depending on the road / track mix.
Kind regards

Also worth noting that a car set up for road use can also eat tyres, although differently, when abused on the track.
I've had my TT set up for a bit of both and found it much easier on the tyres during a recent bedford trip probably, because it's not constantly peeling the outside edge off the rim.

have only adjusted the camber at JAZ to 1.7 frnt and 2.5 rear which gave vaery even wear on my cup tyres in the summer months. I put cups on in April until October.! set lasted two summers ad about 12 track days(including 2 visits to Spa and the Ring!!!!)but they only had the circumferential grooves on at the end (apparently were still road legal).Am still on my origional tyres PS that the GT3 came with altough the rears are worn on the inside....Agent Orange HHHMMMMMMMmmmmmmmm!!!!!!!! see you soon Peter
