Yep Jarrod has the uber rare 17 x 9 et 70 Cup 2's on the front. I have three 17 x 8 et 70 and I am going to get some 245's mounted and put a pair on the front. IIRC GTS's came with 17 x 7.5 et 65 fronts and they are pretty rare too.

Panamera 19's are:

9Jx19 ET60 front
10Jx19 ET61 rear

I'd say the 8Jx18 ET59 are a better fit - the wider 9 inch width on the 19's will push the outer edge out almost half inch.
