What does a guy do to combat a really rough track? The one we raced on this weekend was like a plowed field. We were told that lower the panhard and making it level would help alot. Any other suggestions?

What we were told about the panhard was that, lowering it and making it level causes the car to not roll over so much.

According to AFCO, you are suppose to stiffen the springs and shocks so you don't get the wheels popping off the track so bad.

Cowboy, You are correct! When the track becomes very rough you want to slow down the reaction of the tires, so you would stiffen the shock package as to keep the tires on the track longer. I would however leave the spring package alone but raise the whole car up about 1/2".
Good Luck.......

Doesn't lowering the panhard lower your roll center thus, making the car roll less?

A comment on the panhard bar: There are two different ways to "lower" the panhard bar.

(1) If you lower the panhard bar on both ends (pinion and frame), you have lowered the rear roll center. A lower roll center (using the same spring rates) will create more body roll.

(2) If you lower the panhard bar on the pinion OR the frame--but not both--you have changed the angle of the bar. This does not drastically affect the rear roll center.

These two different changes cause different end results.
