Default Stock camber and toe values?

Anyone who has the stock values for camber and toe-in (European if it matters...)?

Current setup is:
Front camber: 1,5 degrees
Front Toe: 0

Rear Camber: 1,5 degrees
Rear Toe: 1,5mm

As I understand it the previous owner chose this setup to get more oversteer rather than understeer.
The problem is that the front tires are wearing "a lot" on the inside.

I will run the car mainly on the street.
Should I go back to stock values?
Any other suggestions?

The front Toe is fine per specs for a 100% street driven TT.. I prefer to have a bit more than that for sharper turn in.

As far as camber is concerned, in my opinion what you have is excellent for the street, but to answer your question, you can go to zero degrees front camber and reduce tire wear on the inside, however you will loose a lot from the handling of the car.

On the other hand the car is somewhat safer for a new owner with understeer vs oversteer.

I am not sure what sort of increased tire life you will get by going to zero camber, and what sort of improved gas mileage, but I know that when I am driving a 400HP car sportscar, I want it to handle perfectly (i.e. neutral).

These are personal choices.

Your rear toe reading seems to have a typo.

Thanks Jean.
I think I'll keep the current values as they are.
Yes it will wear some more on the inside but as you write good handling is preferred.

The unit for the rear toe is actually [mm] according to the protocol.
I was also a bit surprised that it was a length unit rather than an angle unit...
It also has no + or - in front of it, but I assume that it is toe-in.

Do you by any chance have the stock number?...just for comparison.

As far as I know toe is measured in minutes (mn) not millimeters (mm). What you might be referring to is the kinematic toe, which is measured as the difference between two of the suspension arms with a Porsche special tool. The difference between those two arms should be 1.5 scale units (no plus or minus), but that is not the same as the toe.

In the rear, the stock settings are +10' +/-5' and the difference between left and right should not exceed 10'. This last one (difference left/right) is more important than the actual number itself. Stock RS settings are +15'.

Front, between 0' and 5' you are within spec. IMO 0 minutes is too little though, I have 8'.

Jean, a RS setup might be the way to go for me.
Is it ok also for 4-wheel drive?
