3R is probably good for close to 1 sec improvement for every mile of track I'd say (of course depending on the track). Quite a bit stickier and last maybe 25%-35% as long as the 3's. Problem is more stick = more suspension lean, so need stiffer setup and more camber to really use the tire properly. I think regular 3's are a damn good match for a stock street/track ZL1 personally with track alignment settings.
