Another tire you might check out (that I will be putting on the 330CiC when it needs new tires) is the Toyo Proxes T1-S. Grippy as hell in wet AND dry, excellent life, and lots of tread. Looks cool too.
They have a trial period where you can try them out and get your money back if you don't like them. That was why I took a chance and tried them out on the C5, and I couldn't be happier. Keep in mind that my car's tires are 295 wide in the rear and 265 in front, and they are awesome in the rain (won't hydroplane) and dry (sticky, sticky, STICKY) so on a car with less power at the wheels they should be awesome.
Give them a try.
