What are the widths and offsets?

Edit: did the leg work for you

Rears:
GTS 19x11 et51
GT3 20x12 et47

Compared to your existing wheel, this new wheel will have an inner rim which is 8.7mm closer to the suspension strut. The outer rim will poke out 16.7mm more than before.

I did some detailed analysis on willitfit.com

Fronts

997 GTS 235/35/19 8.5 wide ET 56
991 GT3 245/30/20 9 wide ET 55

Rear

997 GTS 305/30/19 11 wide ET 51
991 305/30/20 12 wide ET 48

Looks like this will all work out. Anyone know if the CL itself is the same between 991 and 997?

Thanks
