Thread: Proper spring rate for my 34 3 window

Tweet

Is this a glass car or steel car? Does it have a trunk or rumble seat? Regardless, 600 pound springs sound too stout to me. I think this is your problem. Look for a color paint spot or ring around the top or bottom coil. This is how most companies mark the spring for easier identification. Then make some calls to Aldan or the like. They can let you know what your have.

As for the rears, I fought this same problem until I replaced the coil-overs with Shockwave Airbag coil-over retro-fits. I can't say enough about these shocks and the people who work there! Now, the car rides better than it ever has. Without a doubt, this is some of the best money I have ever spent on the ol' Hot Rod! I have a dropped axle in the front with a Posies I bought from P&J. I used to have one of the popular "One-&-Only" Mono-leaf front springs from Durant...But it broke in half at 75mph after 4,000 miles...Bad deal and they didn's stand behind the product at all...but that is another story all together.

These pointed-nose cars have such a short wheelbase and limited room for suspension travel, it is difficult to make them work. But not impossible.

I have learned the hard way about how important it is to work in small increments with the front "and" the back to find the "right" setup. If you change too much too quickly, one change in the front will effect how the back rides...and visa-versa. One wrong setup will "over-emphasize" the other. I found that one mistake in the front or back would cause the car to "buck" and make you say things you shouldn't. But once you understand how both setups effect the other, you can zero in on making them ride well.

Since you have a 3 Window (very cool by the way), you certainly don't need the air-flexibility like I do with a sedan (since you won't have casual passengers which immediately change the rules of your setup). But they do come in handy when you load up the trunk for a long trip or if you do have a rumble seat and add passengers. You might not like the look of them, personally I like the look of coil-overs better, but since this car rides like a newbie, I can't even think about taking them out. My next change will be to install one the Limefire Airbag front suspensions so I can better improve the front.

I bet if you lighten the front springs you will solve your problems.
