3 link with left spring in front, right spring behind. 22" Panhard behind axle, and solid pullbar. Since going to this setup I have had to move ballast to the right to loosen the car and am down to 47% cross 58% rear and 52% left.This did keep the car from being too tight to drive. I am presently 60lbs heavier on the right rear and still tight on late entry to the apex of the turn. The good part is I have great side bite and forward bite! I read where Jammin went to more left front spring, will this help?
Any help from real experience would be appreciated!

The reason for the good sidebite, is your lack of crossweight. This means your right rear tire and left front tire are carrying 53% of the weight of the car. When the car transfers more to the right rear in the turns, your probably around 57 or 58%. You may get away with this on a tacky track, but if the track gets slick, your gonna be out to lunch. I suggest adding cross, this will loosen your entry and give you even more forward bite out of the turns.

Jammin,
You are right on, my first night out with this setup at was at 49% cross and 54%left 58% rear. It was nasty dryslick and it worked great. The problem is on tacky tracks I seem to get a huge amount of throttle push and am looking for the happy medium. Moving ballast to the right tamed it down (still some throttle push) but will surely make me loose on the dryslick tracks. I guess I am trying to find the best way to compensate for changing track conditions... What effect would the panhard have on a car that pushes under throttle?
Thanks,

More angle, less roll, less transfer, tighter, better left rear bite....less angle, more roll, more transfer and more right rear bite. Gotta find that happy medium for your track.

Thanks Jammin,
I will go back to 49% cross and put some more roll into it with the panhard. I see your point, the panhard will loosen the car as it rolls, thus my crossweight does not need to be backed off so much - I will know by Saturday night!
Thanks again!

Thanks Jammin,
The car was great until I got caught up in pile-up. This is the best I have run on a tacky track with this setup, the extra body roll loosened it up enough to really help and the cross is back to 49-50% range. Bite off the corner was great.
Thanks again for the good advise.
