I've had the original Bridgestone R040's, Bridgestone S-03's, BFG G-Force Sports, and Kumho AST's on my car.
The BFG's are by far the best bang-for-the buck dry performance tires. The S-03's handle great too, but for twice the price with only half the tire life.
The holeshot traction and braking traction on this tire are fantastic.
Check the dry performance numbers at Tire Rack.
This tire has won the stopping distance category in two separate tests against quality competition and is 1st or 2nd in every slalom and track time category.
It gets slightly outperformed in wet conditions, but who cares, I don't push my car hard in wet weather.
It also sucks in snow and weather under 40 degrees, but I've got my AWD Celica for that kind of weather anyway. Summer handling is what this tire is all about.
Lastly, the G-Force Sports were pretty darn quiet, definitely not louder than my AST's or S-03's were.
I just had a new set of G-Force sports installed again yesterday (goodbye you all-seasons) and I'm very excited. I was so upset the first time I drove on the AST's and realized how much performance I had given up just for some all-season capability. Glad I finally wore 'em out.
It cost me $570 installed at Discount Tire for (2) 225/45/17's and (2) 245/45/17's, but I also have a $60 mail-in rebate coming. So, call it $510 total.
