22 mid motor setup

[Madman1]

Hi just got a new 22 and built it mid motor cuz of the high bit that my local track has. And I'm having a really hard time finding a good base line setup to start at. The track I run at is high bit clay (wet) and as the night goes on it starts washboarding. Car works really well right now but very twitchy. So if you guys could help me out on a solid setup from tires to shock piston and everything embetween I would appricate it. Thanks.
