Loose on entry, tight in the middle when I get on the gas and a loose off because of the tight in the center. Anybody got a magic fix for this. Leaning toward a spring change. Softer right front???

tell us how it scales out, and what springs you have in there right now. try to fix the first problem first (loose on entry) by tightening the car up

Try a 175 in the RR.. if your car is heavy or rolls too much, put a 250 in the LR instead. 50 cross is a bit low if you're an experienced driver

try the 250 left rear spring. also try different offset wheel lr to move it out it will free center tighten exit.wheel offsets play more of a role on good chassis setup than you may think.
hope this helps.any other ?s just ask this forum is a information goldmine its too bad most of us dont have more room in our heads for all of the info availabe on this site.

hmm.. you must have some ballast in to get 53-54 rear%. you could try taking some of it out. low cross works better with a low rear%. and if you do have ballast, is it right over the rear axle or back by the bumper?

Ryan try a drastic air pressure adjustment. I had this problem trying to run 12 psi in the rear tires the car was loose getting into the corner until the tire caught up with the roll or the tire (center of the corner) this made the car push bad in the middle and due to over correction the car became loose off the corner. added air to the rear tires (14-15PSI) and the car became more predictable.
After correcting this problem I found the car was tight on entry and then i corrected this problem.

This is only one correction to a given problem without knowing a large amount of the rest of the puzzle, your trouble could be much more.
After reading some the resonses and not having your car in the shop in awhile you may need to return to some original notes and base line set-ups.

I would probably go softer on your front shocks or take a little bite out of the rear. Either one should get it through the middle better.

Good Luck.

Took some left side weight out and it was a bunch better, but the track stayed fairly tacky through out the night so who knows.

Ryan, Could your original problam of the "loose in" be brake related? The only time I get really "loose in" is when the track gets slick. If I reduce the rear brake some, it seems to help entry and then the middle gets better too. This doesn't work for me if the track holds moisture and has a lot of bite.
