You might want to increase your rear to about 60%,also might want to increase the angle of the panhard bar and add some lead to the rr frame rail.I see alot of guys around here that run the new Harris chassis are running a short pinion mount panhard bar and are fast on the dry-slick. Hope this helps.

You can also try changing rear shocks to straight 93's if your track is still fairly smooth. The 93/5 is basically holding the left side of your car down precisely when it needs to roll the most. The 93 rr shock will also let your car get over on the rr more on initial entry as well. You can also go to a 75/3 left front to help this even more. I have also found that about 1/2" more ride height is beneficial on the slick tracks.
All of my suggestions are going to help you on initial entry, for the most part. More rear % and RF/LF cross will get you up off the corner after that.

Keep us informed on how it goes.

Something sounds like it could be bound up on rear,you should get a lot more travel on pull bar with 600 spring(you may need deeper gear)3 inches would be better.let us know what you find.
