How to fit female (Fujimi-Aoshima) wheels to the back of a Tamiya
Take the rear dif and cut off the drive shafts,
Drill the dif out as shown with the red circle with a 2.5mm drill.
Using a 2mm dia steel bar (like you get in a Tamiya 350Z kit) fit thro' the dif. and cut to length to suit your needs.
2mm Steel Bars can be purchase in packs of 10 off from : www.hiroboy.com
I have used Fujimi Brembo brakes,
but I'm sure SAS's new brakes (follow this link for SAS PE Brake Discs)will work as well and look better.
