If your looking for a nice, lightweight max performance summer tire. You can get continental extremecontact dw (not dws) tires very inexpensive on tirerack right now (at least you could a couple weeks ago and they mightve sold out) in 205/55/16. I just got them myself a couple of weeks ago, they were on clearance for like $280 for all 4 before a $70 visa gift card rebate, so basically $210 bucks for an incredible tire! And it was the lightest max performance tire I could find. Same weight as the hankook evo v12s, but a much much better tire.
Also if you want less extreme performance but awesome fuel economy and respectable performance, the pirelli cinturato p7s are super lightweight with low rolling resistance for even less after their $60 visa card rebate. That was so close for me.
My 16x7et30 lightweight wheels are being made in the uk and are taking forever! 15 week production! Im dying to get them and put them on with my new extremecontact's!!
