U should try swapping the rear springs...the stiffer rr should tighten entry and softer lr should keep a little more load on the apring when on the lr limiter and help it settle smoother on decel

You say it's tight in the middle when you made the other adjustments. Did it fix entry? Was it tight on the throttle or off? Based on your current setup and the initial issue, I would swap the front springs and shocks.. You're pinning the LF getting in the corner with the springs and shocks as they are.

put the jbar and left lower back where you had them....for entry only - stiffen left front, lower right lower bar

Do you have a spoiler? do they? even a 1.5 is enough to plant the car on entry way more than a car with no spoiler.

If you have a spoiler what angle is it mounted at? Adding angle is going to increase down force which is mostly felt on entry to middle

Agree with Dirtracr 33. Also make sure you have 0 deg indexing on the RR birdcage. JMO
