New Speedster Front Sway Bar

Very cool, Jim.

I know you are set on welding pickup points onto the lower arms. Just to let you know, in the last few thousand miles, I have experienced ZERO fatigue or bending of my coupler nuts/shock studs/10mm bolts to attach the 10mm heim joint downlinks.

I have been doing a lot of research on Formula Vees lately. If you've checked them out, I'm sure you've seen the front shocks moved to line up behind the beam uprights. They use a special cast piece up top, but on the bottom they use a stud/nut extender to move the shock over a good 1.5 inches.

I'll submit that I have zero scientific evidence that this is OK. But almost all Vees have the shocks hidden in this manner. And there have been countless Vees run for a lot of years at 120 plus mph on countless tracks all over the world. This leads me to believe that my method of downlink is just fine.

Anyway, in the end, you do you. Just trying to make your construction easier.

Danny, I figured that if you had any trouble with that arrangement you'd have mentioned it, so I'm going to give it a try. I'd appreciate a photo of your installation.

Thanks

No problem, Jim.

Thanks Danny

I really, really like that, @DannyP. Well done. Well done, indeed.

Very well engineered !

Jim     Why are you using 4130 steel ?............Bruce

Thanks gentlemen.

Here is the best picture of the bar that I have. I think it's 3/8"(don't know which steel)water jet cut arms. The collars are 5/8" id, and were welded to the bar first on both ends. Then just the collar edge is welded to the arms.

3/16" and 1/8" mild stock for the bushing mounts.

Hey, Jim, I found a Formula Vee photo today that might be of interest.

A Vee only has 500 pounds max on the front axle instead of 800 or more on a Spyder/Speedster. From what I've read, the trailing arms on link-pin are weaker.

These shock extensions seem to work just fine for racing though. I know a swaybar is not the same loading as a shock.

Wow...it's hung way out there. Is that just an extension from the shock mount? The Super V's are really interesting. None, that I know of, in my part of the country. I'd love to see them run. Thanks for the photo.

I have all the fabricating done on the sway bar. Just the fitting and welding remain. I'm not a paying member sooo, Theron no longer allows me to post my design documents.

I'll post a link for the drawings when it's all completed.

@Jim Gilbert - Madison, Mississippi None of your photos are showing.

Jim, yes it's just an extension on the stock mounting for the shock.

And Super Vee have Rabbit watercooled motors.

Formula Vee has three classes, Formula Vee(1200cc and Hoosier slicks), Challenge Cup(1200cc and Yoko 200 treadwear street tires) and Vintage Vee(1200cc pre-1973 cars). They race at Roebling, Road Atlanta, and Sebring and more down south.
