Default Can a sprint car type torsion bar suspension work on a street driven hot rod??

Like sThe subject says. I like the clean look and sense of purpose of sprint car suspensions. Perhaps with less machined aluminum and more fabrication.

Rear suspension to be specific.

My buddy scratch built a 27 T roadster with a flat head and a quick change and installed torsion bars from a sprint car. Came out real neat and although he does not drive it much he says he was quite satisfied with the ride

Yes. Here is a link to the Moal chassis. And the price is very reasonable, considering the craftsmanship and engineering. Gary

You need to check out Joey Saldana's hotrod, torsion front and rear I think. built and set up by Lee Osborne. Who was one heck off a shoe himself.

Moal sells their torsion bar suspensions separately if you don't want their frame. Michael Moal recently quoted me $2,850 for the front or rear. Sounds like a lot but it is an engineered system. I have ridden in a car that they built and it is really worth the bucks if you have them.

Yes you can put sprint car torsion bars on a street car. With a solid rear axle 8", 9" it is fairly simple, with a I R S it gets a little complicated.

Built one in the seventies with sprint car stuff and it was really a cool ride and totally adjustable. 1940 Ford chassis.

What is the concensus of orienting the torsion bars in a horizontal fashion (as shown in the pics) versus a longitudinal manner?

Was it the ride quality or the handling? How much better is it than a spring system?

Just curious.

Ride quality. I was not driving. It was very smooth and there was very little lean in the turns.

I saw a Model A at the Tunica show with a home made torsion bar suspension. It had the bars parallel to the frame and the ends of the arms rode on pads welded to split original Ford wishbones.

Schroder Racing (the same people who make the sprint car steering boxes) make torsion bars and they can size based on load and the length of the arm.

I think that setup would be really cool. I would
LIke to be able to set the torsion bars within the frame rails for a super clean almost skeletonized appearing suspension.

These pictures are not very clear but they show the start of a torsion bar suspension using Toyota and Chevy luv torsion bars. More pictures in my albums. For ease of mounting torsion bar arms, in my opinion the rear bars would be mounted transversely or across the car. The fronts run parallel to the frame.

As many torsion bars and stops I have left over from racing this thread has me interested.

Steve Panaritis (aka The Greek) has being doing torsion bar frames for years here in Indiana and Lee Osborne was doing them before him.
A coil spring is simply a torsion bar packaged differently but the advantage of correctly mounted torsion bars is that the spring base can be made wider and longer without having the coils hanging out in the breeze.

The springbase used to be a sort of critical item on old midgets, maybe they were after that...but on a hotrod hidden would be nice.
