Here is something that I keep thinking about. Converting a sprint car frame over to a buggy. First of all they are tough. And light. Anyone who has been to a sprint car race knows that. If you look at the frame. I just pulled this one off google. It looks like it would be easy to put a torsion and a beam on this frame. An engine cage would be easy to build. Also with out the engine in the front you would have plenty of leg room. Also I think I would like the ability to mount my seat 8" off the floor. And then keep my legs at a more natural angle for driving. Not flat to the floor. I know that raises center of gravity.Anyway this is something I have been kicking around for awhile. I almost built one for a guy but he backed out.

Dean, my concern would be the center of gravity being that much higher how would it affect the buggy on hills if you climb with it. Structurally they are tuff thats for sure to be able to take the hits and rolls some of them go through wrecking.
Would be different the only way to know is to build it and experiment with it.

It varies. Usually small diameter thin wall chromoly. I had one here for awhile till the guy changed his mind. Never weighed it but you could lift it very easily. I realize you could build a buggy frame from chromoly and acheive the same weight but you can pick these frames up at swap meets for very little money.

The reason there are so many out there it's cheaper to buy a new chassis than fix a wrecked one, and it dosen't take a bunch to mess one up.
We ran a J&J chassis for a couple of years with no cracking. That chassis is a very rigid, almost no flex in it at all just don't hit anything with it. And chromolly should be pre

my uncle ran a rocket chassis in the dirt late model class and i have seen those frames take some bangin up. i know thats not a spring car but it is made of the same chromo- tubing im sure. if you wreck it and splice in new tubing, they are supposed to handle better because you are removing stress from the original weld-up. i've always wondered why noone had thin wall chromoly buggies, but then i realized my bicycle frame is 4130 and costs 385 dollars, i can only imagine the cost of a full chromoly buggy frame.

I have a friend that is building a Chrome-moly frame. Expensive as hell, but its going to be lite. Then add a 091 with a 2500 motor and that thing is going to be like the space shuttle. Blasting off to no mans land.

my buggy is all chrome moly except for the front bumper. Ive had it for 2 years and the guy who built it had it for a few years before me. No cracks, no problems. I made the front bumper out of regular tubing so it could give before something else did.
