Front camber advice

[schwarzwagen]

So I installed new lower control arms this weekend in the w126 and I tentatively set the camber at max, now the front axle has visibly more negative camber than the rear. The rear is at -0.5 degrees, so I'm guessing the front is around -1.5 degrees or so. The rear has always worn evenly at -0.5, but the greater cornering forces on the front I'm guessing would require at least
-1.0 if not the maximum allowable.

What settings are best for performance driving without abnormally wearing the tires?

If I remember right, the sportline 300s were around -1.33 degrees in the front from the factory, alert me if I'm wrong (grey matter is fuzzy). So, I figure -1.5 is probably good. Keep in mind that I have always worn the outside tread blocks out first on every previous set of tires on the factory camber setting of 0 degrees.

How much camber do people use at the track on their 16v 190s and the like?

Just trying to get a feel for what I should set it at, thanks for any help!
