The Pilot Super Sport, as said above, is replacing the Pilot Sport 2. It is cheaper, last longer and performs better in every condition. Here is a quotation from Road & Track's review:
"Compared to the Pilot Sport 2, the Super Sport laps about 1.5 sec faster on a racetrack, can stop almost 5 feet shorter from 62 mph in the dry, and stop nearly 10 feet shorter from about 50 mph to 5 mph in the wet. On top of that, the new tires have a 10-percent longer life."

Michelin Pilot Super Sport Review
My car has 18s and for a full set of tires it is $1,008 for the PSSs on Tire Rack, which is about $300 cheaper than PS2s are.
