Going with a set of 4.29 or 4.30's. (33" et street and 33.5" slicks) I talked to Strange and they felt with limited heat on the gear the pro gear would be my best choice. I also talked with Larry Larson and he said to stick with the pro gear. That's kind of what I thought.
Tracy, IMO If you 1/8 mile race with a 29" tire the 3.70 would be good for you.
