I have the gforce sport, I love this tire, price was perfect and its been such a good tire. Hooks up real well wet and dry. Id definitly reccomend any of the bfg gforce series.
I went with some Falken ZIEX ZE512 275's all the way around. I don't hear much about them, but I got a good deal on them for like $110 a piece and they hook great they don't even spin when I drop the clutch! Can't beat the performance for the price.
Sumitomo. They are cheap, you can burn the crap out of them, buy a second set, and you still paid less than what one set of a different brand would've cost you.
Since you don't appear to have a power adder, or do road racing, I wouldn't think you'd be dissapointed. I know I'm not.
