ResinRick:
3/4" is already pretty aggressive for a wood track. If you move it back any farther you'll need to recheck alignment and make sure it's better than now. Last year at district we ran on a 32' wood track that was in good condition. We ran an average of 2.4018 @ 2nd and the fastest car ran a 2.37xx time. We didn't have lightened wheels at all (didn't even know about lightening them at that time). Don't know your rules but, if not done already, you could raise a wheel, steer the dominant front wheel into the rail to make it stay straight. If your wheels are only half the original weight @ 1.8gr then I would lathe them some more down closer to 1 or 1.1gr and then you can add a few hundredths of an ounce in weight on the back of the car. That will give you a faster start and give you a better chance to win( I know lathing would have helped our time a lot). If you only polished the axles say to like 2000 grit then buy much finer micro mesh sandpaper and polish them more, polish the inside of the wheel hubs, etc. And of course, relube and make sure it 's run in well. You've got a month, that's more than enough time to get it done. So "Git 'R Done"

Suggestion from past "bad" experience. Start with a new set of wheels to get them lighter. If your current set is running "pretty good" don't take the chance of messing up "pretty good" for "disasterous". I'm notorious for over engineering a thing to death. Also pay attention to burnishing all rubbing sufaces: hub bore, hubs, car body, inside edge of wheel that touches the track.

Good luck!
