long front wheelz
 

i did this mod and it improves stabability, turning, & straightness. all you have to do is get a kit racer and take the front tires of it and cut the metal thing connecting them in half. then put them in the kn=uclkes heres a pic.

Another way is to take Pullback tires and put them on your Bit. To stop gear interference use an X-Acto knife to trim off ONLY 1 mm of the rubber.
