Front Sway Bar designed, fabicated, installed and tested!

Postby JRGilbert » Mon Mar 19, 2018 5:56 am

You may remember the discussion several months ago concerning from anti-sway bars for the Spyder.
I found nothing available that would work due to the tube frame. Stock VW sway bar will hit the frame.
DannyP pointed me to a concept drawing on another list, posted by CarlosG. His concept was the type of bar I was looking for.
The execution required some more thinking.
I have completed the project and am well pleased with the results.

My bar requires a considerable amount of milling machine work.
Bar ends are splined and torque arms are machined from 7075 T6 billet aluminum.
If you are unable to do the work yourself, it will be expensive.
Fabrication and welding of the mounts is required.
Heim joint linkage connects the torque arms to the lower suspension trailing link.
The completed system is highly adjustable.

If there is enough interest I will post to the site.

Cool.
Please do post some pictures.
I'm that Carlos G guy. I haven't been able to bring my idea to life yet, but I'd love to see what you've come up with.
I would also like to know what size bar you ended up using, and the effect it had on handling.
If you can't post pictures on here, then post them on the Speedster site.

Thanks
Carlos G

Jim's bar looks good, but he'll have to post photos. I don't bother here, it is a pain to reduce them to such a small size.

I think it's a 3/4" bar that Jim used.

Lenny and I are working on 5/8" versions for our cars, we'll fill everyone in when we get further along. I'm using urethane swaybar bushings from Summit, but Lenny is using brass/bronze bushngs in a tube. We'll both have to have the bars heat treated to Rockwell 38-42 or so. We are using annealed 4130 carbon steel.

I'm planning to weld mine up with flat steel end plates, then heat treat. Lenny is having his bar D-shaped on the end with a matching receptor and a setscrew. I'm using a couple 10mm heim joints for end links to a coupler nut on the lower shock mount. We'll just have to weld on some steel to the beam to mount the bar.
