The best approach would be what Jeff says. Rifle-drilled or small diameter axles, aluminum spool, micro-ed gears, loose bearings, light wheels and tires. MHO

I guess what it all comes down to is if it's a high powered car go for all of the tricks. If it's a "dime rocket" with no power and an automatic (and I'm guessing that the combo that started the thread is) then there are lots of better places to spend your money like really light wheels and tires and the correct size header.
