OK, my self built roadster has been done for a couple of years now and I'm generally satisfied with it. BUT (there's always a BUT, right). The ride quality sucks. On smooth pavement it rides and handles very well...on bumpy roads or going over bridge joints it will beat you to death. Many I've talked to say, "get used to it, it's a hot rod, they all ride rough." My response is "maybe". I'm not quite willing to admit defeat without a fight. My reason in making this post is to hopefully start a serious discussion about ways to improve the ride quality of street driven hot rods. I have lots of questions and if I can find some answers for them that make sense, my plan is to tear into the suspension on my car over the upcoming winter "down time". Here's the specs on my current setup. The front end: 3" dropped axle with Bilstein "shorty" shocks, Posies spring, hairpins and panhard bar. The front is fine, never bottoms out and rides good. My plan would be to leave it alone. Rear End: C notched frame, with ladder bars, Bilstein shocks and coil-over springs. The shocks have 3 inches travel from fully collapsed to full extension. Springs are 8" length, 150#. Ride height is set at 11.5 inches eye-to-eye on the shocks. These are the settings recommended by Bilstein. There is approx 2.25" travel between the axle and the frame. I have played around a bit with different spring rates and 150# seems to be the best compromise. Now, my questions: Is it simply a matter of shock travel? If I make the C notch deeper or do a mild Z on the rear of the frame this should enable running shocks with more travel. Will this and some appropriate tweaking of the spring rate equal better ride? I realize the rear floor and subrails would need to be modified and I'm OK with this if the fix will make a dramatic improvement in ride quality. How much shock travel is necessary to improve the ride? I currently have about 2.5", which obviously isn't enough. What's the magic number here...3"...4"...??? I had the same problem more or less with the coupe I owned before the roadster. I tried lots of different shock/spring combinations and while some were marginally better than others, I never got it to ride as good as I wanted. I'd like to hang on to this roadster for a long time, and it sure would be great if it didn't ride like a log truck. 'Appreciate input from folks who have delt with this problem and solved it.
