Cougar KF Gear Diff.
 

Hi All,

Has anyone tried to run more than they 12500wt in the rear diff on Cougar KF, on Astro or carpet and if so what are the advantages or disadvantages been ...???

I am running 20,000 in my KF at Silverstone. Was recommended by a team driver and works well for me. Gives more forward drive out of corners. Had to increase rear toe in a bt to make it stable.
Have tried the same diff setup for lower grip tracks and it does not work. You need the high grip surface to get the traction out of corners. Have tried ball diff for lower grip and this works for me.
