I'd like to know more about this too. In my very non-expert opinion, ball diff probably offers the best flexibility. Front one way encourages rotation at the cost of off throttle stability, so this might be good on a track with very tight corners, but keep in mind that one way bearings can wear out over time. From what I've read, rigid axle on the front is common with 1/10 scale touring cars, so this would be worth experimenting at the 1:28 scale. With a ball diff as usual, set it loose to have more rotation, and set it tight to have more stability.

Hey there, thank you for the video. Very informative. Do you by any chance have a link for those track barriers?
Thank you. I didn't purchase them myself but found them on aliexpress www.aliexpress.us/item/3256804758097979.html
in your opinion, what's the best setup for the front diff on the AWD for grip racing, rigid vs ball diff vs one-way?
