I was wondering why nobody produces these?? It would be so benificial to the handling of these cars. You wouldn't have to run near as much (or any) stagger, the car would not scrub off near as much corner speed, and it should allow more heat into the left front tire. I know my old WCM K1 car had a ball differntial, but, I could not retrofit it to the K1E chassis without mods that I did not want to make. Ace Rossi made a version of a differential, but I belive it was nothing more than a one way bearing in a hub, and it suffered durability issues. It would be cool if a mfg. came up with a nice differential to be used in these cars.

I don't think anybody really wants to add more rotating weight to their car, although I think getting a Torson diff to work could be very interesting.

If the stagger is right and the car is set up for it I don't think you'll scrub speed because of this. In fact, just the opposite, I think you can pick up speed. It's why the ole NASCAR boys run a locker diff everywhere but the superspeedways.

I'm not disagreeing with you. I think a diff would make car set up easier but I also think a locked rear, set up correctly, would be faster.

A Torson diff works just the opposite of an open diff. and similar to a clutch diff. It allows differential action but limits power to the spinning wheel. Maybe when I retire...

I agree, a ball differential is a huge tuning aid in 10th scale. I know the cars are way different but most of the same principals apply no matter what size the car is. I have seen guys run spooled diffs in dirt cars as well and they usually go back to the differential set up for better speed through the corners.
