[QUOTE=rfleck;13808447]I've had spur gears chip in the past when running on super hard packed big air tracks. Curious if others who have had this same issue tried the one piece motor mount plate and had success. Also, for thise who have this piece, it it made of a higher quality 7075 aluminum or is it cast? I love the car, but hate this one issue.
The U-shaped piece (IFW456) is made from 7075 aluminum and works great. I use that along with the (blue) 777 motor mounts (IFW102) and a 1mm shim under the center diff.
Although there is still a little rubbing of the clutchbell on the chassis, it never causes a flameout or any other issue.
