Thread: My 32 rides so rough I need suggestions on set up!

Tweet

There are some tech articles at the Ridetech website that may be helpful. I read one where they claim that in the past, it was common to use springs that were too stiff, with too little range of travel.

As an example, the back springs on my Oze '37 have a spring rate of only 200 lbs./inch and have a full range of travel of 5 inches. The springs are canted at about a 15 degree angle. Apparently it's not uncommon to find cars with a similar setup that has much stiffer springs and far less travel range. To get my current ride height, the length adjustment is set such that there is no preload on the spring, it the car is raised off the ground, on a lift. No preload is ok, but if the length adjuster is turned down much more, the springs hang loose and don't automatically center themselves around the top mounting area. When the car lowered, you have to let the tires touch the ground slightly to get some preload, then push on the top of the spring to center it.

My car rides fine on a smooth road, but a big mismatch in the pavement still seems to produce a pretty hard reaction. Someday, I'll contact ridetech to see what they think about reducing the spring rate a little more.
