SAV/MAXX/MGT 14mm WHEELS TO FIT ETK/NTK...
To mod most 14mm wheels for the front I found some cheap 5/8 home water line plastic pipe at home depot that the inside diamiter is a perfect fit for the factory 6x12 front bearings. I drill out the wheels slowly using a 1/2 then 9/16 and finaly a 5/8 drill bit, I use a drill press to do this but it could be done with a hand drill also. I make a correct size bearing spacer from the same pipe and use 2 small set screws to hold the whole assembly in the wheel by drilling 2 small holes through the center of the wheels on each side and inserting the set screws. The fit is so tight that c/a glue might even hold the pipe in the wheel.
For the rear, just buy a set of aluminum 14mm x 6mm (mgt/max) hexes and preferably use a modded/sharp correct size allen key and punch the key through the hex with hammer or press through with using bench vise, a screw driver bit could even be used, a sharp edge on the bit/tool will cut a real nice correct shape for the factory axle.
