My 1st Gen currently has a 4.88 ratio rear gear. I have a spare 3.90 ring and pinion. One of the tracks where I race is St. Louis where we use about 1/2 of the Nascar oval. A very long all-out pull. I'm wondering if it would make any sense to use the 3.90's at this track in an effort to get more speed on that portion of the track??? There are only two really tight turns on the infield and I know I would lose some there. The left hand turn onto the oval is the tightest and the slowest part of the circuit. Anyone have any suggestions???

Thanks,
Scott Goble
