Either V12 or pay a little more for Conti DW. Based on what the OP described, PSS is not worth the extra money. A DW is also light weight, anywhere from 3 to 5 lbs lighter than most other recommended tires.
I am big on unsprung weight reduction. Just installed 18" F14s and DW tires, dropped 9 lbs of unsrung weight at each corner, that is compared to my stock 17" with RFT. The weight loss is very noticeable, I have a section of freeway incline to measure my mods
and the car definitely pulls much harder.
