Lightened ring and pinion, aluminum spool, gun-drilled axles, aluminum flywheel,lightweight aftermarket "stock" clutch or a clutch from a vette, lightened gears in your tranny or just removing the gears you don't need, smaller diamter/lightweight driveshaft, lightweight crank. If you don't have a large budget (like me) just try and get some lightweight wheels like outlawstock17 said. Once you start buying lighterweight parts your wallet is going to get a lot thinner.

You might want to go to http://www.parkercarburetion.com/calculators.html and download the Moment of Intertia v. 2.0 calculator. You can play with the dimensions of various items and get a good idea of how the moment of inertia is affected. It's a little oversimplified but will tell you where you'll get the most bang for your buck.

One thing you'll quickly find is that the distribution of weight from the centerline of rotation is critical. Enter some figures for both solid and drilled axles to get an idea.

Weight off the clutch will make the biggest difference for the money. In a hobby type car lightened ring gear and wheels won't make difference. The wheels are driven at a 5.5 to 6.5 to one ratio so the motor can overpower these heavyweight items faily easily.

Synthetic fluids everywhere are easy changes and worth it. Try reading this post for a stock flywheel combo.

Good luck,
