Guys, I will tell you that I had a very fun and pretty good run with the Mayhem at the track yesterday. Here is what I did.
I put 3F, 7C, 1R diff fluid in.
I shaved the top A arm enough on the front where it attaches to shock tower 2.43mm to match the size of the clip that is used on the rear hub. So I had a total of 4.43mm shims behind the top A arm pushing it forward for much less caster. Big change in the steering and got rid of a lot of push.
Also installed the Ackerman steering. Push entering turns is Gone.
This made the buggy perform great. I just need to learn to drive it better.
Also I got some advice at the track to run 40 shock oil in front and 35 in the rear.
