Can I make it Faster?
 

Is there anyway to somehow speed up my Z-Car with out changing anything?

maybe some kind of tune up or something?

just get the 3.0 motor kit. it's cheap and you get the 3.0, red racing transfer and axle gears, plus an 8 point pinion gear. it makes a big difference. i have that in mine and i just push the motor closer to the transfer gear. it makes it smoother and quieter. you also get an adapter so you can use bit bodies on it.

ok, but on Tiny it says that you can make a Bit car faster by just letting the motor spin freely for a few minutes. does that work for Z-Cars?

thats just to free the gears etc from dust and particles :P
