I just bought a 99 harris asphalt chassis and I want to convert it to a dirt track car. Does anyone have any suggestions or know if this is or is not a good idea? Thanks.

I had changed a harris from dirt to asphalt for 1 year and then back. (Call harris they will have more info. and are glad to help even if the car is second hand! Great group of guys.) If I recall most of the changes can be made. The lower ball joints are different, the panhard bar will need to be switched to the other side. the motor I think is lower it will need to be raised. Move the battery from behind the driver to the back passenger side of the car and high as practical.
Some of the cars had the upper a mounts for only asphalt. the brackets may need changed.
or additional holes drilled.

I am looking for a number to harris on their web-page and cant find it. Do you have it? I did notice the panhard bar goes downhill from the drivers side to the passenger side. Isnt this backwards for a dirt car?

Harris # 1-800-833 -5174

The panhard bar on dirt needs to be from the drivers side on the Chassis, down hill to the passenger side on the rearend.

Not sure by your post if the drivers side is the housing or chassis?

I was looking at a couple of hot chassis this weekend and looking from the rear of the car the panhard goes downhill from right to left.

Not a typical Harris set up. Hot chassis also had the springs on top of the rearend and 3" off sets all around (I would like having all the offsets the same) anyway.
Some chassis will have different set ups that their car likes. Try Harris's set up to get you in the ball park then adjust from there.

You can do alot of things with the panhard bar that will change the way the car handles.

Check out the AFCO site they have a grat explination on the angles and location. I believe its afco.com

WHEEL OFFSETS IS ABOUT ALL YOU WILL HAVE TO CHANGE. I USED TO WORK AT HARRIS.
THERE WERE GUYS THAT TOOK DIRT TO PAVEMENT AND PAVEEMENT TO DIRT, JUST BY CHANGING WHEEL OFFSETS AND SETTING THE SCALING NUMBERS FOR EITHER SURFACE. FOR THE ASPHALT CAR TO DIRT, SET THE FRONTEND AS CLOSE TO THE DIRT AS YOU CAN, USE DIRT RIDE HEIGTHS OR AS CLOSE AS POSSIBLE, AND WHEELS OFFSETS FROM THE DIRT CAR. THESE GUYS THAT SWITCHED HAD CHAMPIONSHIPS. PM IF YOU WANT MORE INFO
