My car:
718 GT4 MR
Camber -3f / -2.5r
Toe -1mm f / +2 mm r (both per wheel)
OEM height, rake and sways.
Cup 2R front left looks like this after two hours of a CW track (Zandvoort) running 1:53's.
Not so much worried by the wear itself but more by the pattern. I seem to use only a small part of the tyre.
Is this the part with the softer compound and hence wears faster? Different pressure, camber, toe needed? Driving style*?
Hot pressure around 2.1bar/30.5psi front and similar or slightly higher rear.
More camber -3.5/3.0, add a few more clicks to the coilovers, and stiffen the bars one or two holes per axle. That, and the 2Rs are very soft and don't last that long. That is what happens to Manthey tires on the ring too.
Nice lap and splitting those two at the end. Thumbs on that one.

Agree - maybe a bit higher hot pressure to 32 psi. I've used only one set of Cup2r with a 991.1 GT3. Got 5 30 minute sessions out of them on a 3 mile track... on the third lap of second session of day two, they literally fell off a cliff. Two laps felt great, halfway through the third lap, ice skating.
