Vi-King shock for C4 Conversion

[Fladiver64]

Laszlo, what do you think about making a rear sway bar with a kit like this http://www.welderseries.com/blog/sto...egory=12921497
Could you run this through the frame and then eliminate the interference with the fuel tank. Just an idea, it is hard to tell how this would work.

The issue with the fuel tank interference is the length of the swaybar arms. I'm pretty sure that just about any swaybar is going to interfere with the stock gas tank location since the tank is so far forward. If the stock tank was moved back to the rear crossmember, you have more room but the C4 swaybar still won't fit. IMO the Speedway Engineering swaybars with splines on both ends are a better choice. I don't know if putting the tube through the frame really buys you anything.

My thought with that kit was the spline cups are separate from the arms and you weld them up. That way you could adjust the arm length to move the bar forward. The sleeve bar could go on top of the frame or through it if needed. You would have to order the splined shaft the correct width and then make the arms to fit the location.

As you consider this, remember that the arm length on the swaybar affects the leverage on the bar - shortening the arms loses leverage and will make the bar act stiffer.

It looks to me like that's the case on one end only. The other end is splined. It does give you more flexibility on length of the bar.

Yes the arm length would have to be determined and cut off accordingly. The SE swaybar also allows you to do that. As Rick said, the shorter the arms the stiffer the swaybar at a given diameter. Most C4 swaybars are around 1" (24-26mm) with some being hollow and some solid. The arms are fairly long. We can discuss the preferred path when we get to your build.
