Side pipe mount vibration isolator ?

These things? They just appear to be big-a$$ chunks of rubber on the ERA cars. They do work well though.

Terry- I'll look them over. I assume you have one of theirs, do you know which one ?

Dean, that would be great.

Patrick- That's gotta be strong. How does it dampen the vibration though ?

Apparently that big rubber vertical piece absorbs the vibration and provides structural integrity as well. I'd be interested in seeing shots of what the other manufacturers use.

Oh, ok, I see that's it rubber and not metal. The coloring is about the same.
I wonder how stiff it is ?
(no pun intended)

This is what the SPF has. This pic is too far away but, the 1/4 round part welds to the muffler housing and the two bolts have a type of rocker arm assembly. Larger photo.

That doesn't look that great. Can somebody post a shot of what the Kirkhams use?

Thats not the way mine are made on car# 2592. Are you sure these are SPF?

Like Terry mentioned from that company. See if any would stand out as the best type.

Leveling MountsAbout Leveling and Vibration-Damping Mounts

Select a mount with a maximum load closest to your machine's "load per mount." When using multiple mounts in applications where weight is not evenly distributed, choose each individual mount based on the maximum load it will be supporting. For static loads where weight is evenly distributed, use the following formula to select the proper mounts:
Total Machine Weight divided by No. of Mounting Points = Load Per Mount

Leveling Mounts— In addition to leveling the supports or legs of a machine or other piece of equipment, they let you position equipment above the floor for easier cleaning and inspection.
Leveling mounts that swivel can be used to compensate for uneven floors.
Vibration-Damping Mounts— Isolate vibration, shock, and noise transmitted to and from machinery. They reduce maintenance costs, prolong equipment life, and protect floors. Performance is measured by deflection (the distance the mount material moves when subjected to force). Generally, the higher the deflection rating, the greater the vibration, shock, and noise isolation. Most vibration-damping mounts are used in vertical (compression) applications. Some mounts can be used in both horizontal (shear) and vertical applications. Still others have a steel insert running through the center of the mount that provides support for axial loads (parallel to the stud hole) and radial loads (perpendicular to the stud hole).

This is from a owner of a SPF and it may be different from others.

With the way the Classic Roadster is set up I use a 3/8 thick rubber washer on each side of the flange, a flat washer and the bolt. That is it for mine.
