Well first like to say thanks for all the help on the Bouncing ? it worked.
My problem is that in the wet track it pushes going in and is loose as soon as he picks up the gas.
It's a 4bar z link right side.
Top link on LR is in bottom hole and the top bar Z on RR is in bottom hole
Bottom rod LR is down 5 deg and RR is level.
225 LR 250 RR.
Pan hard is a short bar in 2nd hole from the bottom on pinion.
We run 10" tires(RC3)hoosiers.
Thanks for any help.

well, a number of things
1) is it the driver??? alot of drivers will enter tight, then throw it loose, the tires are broken loose still when they pick up the gas. seen people that have been racing for years do that.
2) lower your rr spring, this will help it out. by lessing the rr spring you will plant it less comparied to the rf, so the car will entry freer(looser) and exit tighter.
3) another fix is more lr bite, this will free up entry and tighten exit, how much do you have now?
4)raise your bottom link to level on the lr
5)raise your rr rearward bar up a hole or two.
6)raise your lr top link a hole or two.
what angles are in your bars right now? put an angle finder on them

Are you sure you dont have your rear springs reversed ? 100 % of all the setups that i have been around calls for softer spring on RR ? Just a thought .looks like you need alot more LR bite also .

I think more cross weight is in order if it is tight while you off the throttle
