Are there any design advantages to running an overslung design as opposed to an underslung? I know most chassis are made as an underslung, but there are still some overslung out there. I am running an older Ellis. Their asphalt cars are underslung but not their dirt chassis. Was wondering why?

Larry Shaw Mods are overslung, and the new Fegers cars are over-rail now too, along with several others. There are a couple of benefits, with the largest in my eyes being clearance for the rearend to move, and easier to work on the rearend and suspension. If the car is a 4-bar car, you don't really need rear bar mounts for a z-link. So, you can also get rid of some weight in the chassis if you eliminate the underslung.

This brings me back to my only concern with an over-rail car. Are they strong enough for weekly racing? I do like having the underslung rails around the fuel cell and rear-end...

Another benefit might be replacablilty: if you knock off a rear clip, it should be easier to replace on an over-rail car.

more flex so cars are easier to set up, and work better on more tracks. many late model chassis are also just overslung.

With the overglung the car likes to roll over alot more through the corner. It gets the weight high in the chassis for dirt.
