". Fullsize Wheelset
This mod simply puts a pair of stock rear wheels onto the front axles, for a complete set of matched wheels like real cars. This gives the car the effect of having a set of 20" rims (see fig.3).
This mod requires an extra set of axles, epoxy or model glue, 2 small washers, and taking apart your front end. Start by taking apart your extra axle, separating the rims and the gear from the axle. (Be careful not to bend anything in the process). Now drill a small hole the same diameter as the axle, throught the rear rims, using a dremel or drill.
Then disassemble your front end and remove your front axle steering knuckles (the white part that holds the rims). Remove the pins from the white steering knuckle, to remove the front rims. There is no easy way to do this, because the pins arent meant to be removed. The pins (axles) look like small nails with ridges at the tip to prevent them from coming loose. Replace the front rims with the rear rims, making sure they spin freely. Because the rear rim adjacent to the axle gear lacks a built-in spacer, you must insert 2 small spacers betw the knuckle and the rim (see fig. 4).
When reinserting the pins, they may no longer be secure especially if you widened the hole when removing it. To fix this, put a tiny, tiny drop of glue or epoxy into the hole from the opposite side of the steering knuckle! This is important because you risk gluing your rim in place by applying glue on the pin directly or on the rim side of the steering knuckle.

i recommend just buying a zipzap and replace the wheels, steering knuckles, and rear axle onto the bit char-g when taking about the bits rear axle try pulling it straight out dont wiggle it out because you will weaken the plastic just dont use alot of force on it
