The basic question is whether you want the absolute stickiest street tires you can get, or if you would be willing to sacrifice just a bit of that performance for better treadlife.
For the stickiest street tires:
Toyo Proxes R1R 205/45-16 and 245/40-17
Kumho Ecsta XS 215/45-16 and either 245/40-17 or 255/40-17
Falken Azenis RT-615K 215/45-16 and 255/40-17
For longer treadlife, you have to take a substantial step down in performance, because there aren't any front tires available for the next performance category down ("maximum performance tires"). You have to get ultra high performance tires, the best of which is the Bridgestone Potenza RE760 Sport (which I think is better than the BFG KDW, another UHP tire). It's available in 205/45-16 and 245/40-17.
