o can u buy the zz turning knuckles seperate from the whole car too?

The ZZ gears fit great on mine, not sloppy or loud. I have no idea if the knuckles fit, and I seriously doubt that you could buy them seperately...

Take it easy...

The knuckles are the same but the rims/tires are bigger. You have to file down the chassis and maybe the body if the zz wheels rubs or binds on the Bit/MS chassis/body.

Here's the chassis sanded to accomodate zz wheels.

Here's a skyline body sanded down so the wheels will clear when on the chassis. The rx-7 I have above did not need the body sanded.
