Tires
Assuming this is what you are talking about, I recently purchased a set of BF Goodrich G-Force Sport A/S tires to replace the original run-flats on my 4000-mile 2003 Coupe.
I can't speak to mileage, obviously, but I am completely satisfied with the tires. Such a huge improvement over the damn run-flats, it makes for a different car. Much better ride, fair amount quieter in the cabin, and enough traction to do a 13.2 1/4-mile with a fairly easy start(car is a stock manual, except for Z06 cat-backs).
Now I don't do track days or corner the car TOO aggressively, so if you are looking for ultimate performance these probably aren't it.
I even got caught in the rain recently, damn it (first time the car ever got wet) and they did fine there too.
Bought from Tire Rack, mounted/balanced locally, I was on the road for $600.
Good luck. Ralph Boineau in central South Carolina
