We are loose off corners with a 4-bar/Z-link. We are wondering if trailing the right rear a little will help at all. Was told this will help out of the corners.

dont trail the rearend.
these will tighten your exit and not effect the car too bad.
1)stiffer lr spring
2)more lr upper bar angle
3)less angle in the rr trainling arm, upper. make it less downhill ot the back.\
good luck

We are good in the heat races when the track is tacky but come feature time when the track is dry slick we are loose coming off the corner. Here's what we have for a set-up.
lf 650
rf 750
lr 225
rr 200
long pull bar mounted all the way up on the drive shaft loop,top hole on the rear-end with a progressive spring

j-bar mounted on the bottom of pinion mount, im not sure what angle off the top of my head

put more angle in the j-bar and put 175 spring in the rr for the feature Saturday night and as soon as he let off the gas going into the corner he lost all side-bite and spun out.

any advice?

It sounds like you raised your roll center when you added angle to the J-bar. I would recommend putting the J-bar back where you started. If he felt he needed more sidebite with that lower it at the chassis or at the Pinon.
I would keep with the 175# spring and go with a 200# LR.
With your original setup I would have added bite to the car. Adding bite will loosen entry and tighten exit.

Move the right side front z link arm down to -5 degree's on a flat to a mild banked track this works well, will also work well on a right side 4bar also...it takes drive out of the right side.

What rear% are you running? Sounds to me like you might need to run alittle more. Also add a bit of j-bar angle. If that dosen't work at the track drop the RR air by a pound. Hope that helps.....

How low can you safely go with the RR tire pressure with having a beadlock?

i go 12, its safe and the tire does not distort like it will. some guys like super low but its not worth it, and can sometimes just heat up and abuse the tires, also you can get less grip sometimes.
