Anecdotal reports from users are not as useful as actual tests. Tirerack's tests are probably filled with scientific and procedural holes, but they're all we've got.
Here's one with the Good Year F1 GS-D3. The tire gets a track rating of 8.08.
Here's one with the BFGoodrich G-force T/A KD. The tire gets a track rating of 8.25.
In my opinion, a tire only needs to be adequate in wet or street driving. You're not really pushing the car in those situations. On the track or in autocross, you want the best tire you can get within the constraints of your tire budget.
