Go for the glass!

I just installed mine a few weeks ago and the difference is like night and day. Just keep your exhaust 2-3 inches away from it. Wrap your pipes if needed.

Fiberglass mono springs are far superior to the OEM steel ones for 4 reasons: 1. Composites react faster to wheel movements since there is much less fricition. 2. Give a superior ride with better handling. 3. Weigh 8 pounds versus 50lbs for steel. 4. Will not sag like steel. You just need to match the spring rate to your liking and suspension setup. I have had a 360 lb on my sport suspension 78 since 1985. On my 78, my 2.5 in duals are about 1 inch from the spring but I do have the OEM heat shield that came on the car with the steel spring between the differential/spring and the exhaust, never a problem. For street driving you should not need to wrap the exhaust. Just maintain a little air cushion and/or use the heat shield from the late 70's vettes. Mine has worked great for 23 years. Wrapping the exhaust also looks horrible from behind the car.

Interesting reading, however, I found a few inaccuracies, surprisingly, in the link. First, 78/79 vettes have a weight distribution of 52% Rear/48% Front so taking 40lbs off of the rear with a composite rear spring, in most cases, is a good thing since it brings the car closer to 50/50 weight distribution. I am not sure why the article says it is not a good thing, especially for the street. Second, the article states that most of the 78-80 vettes had 260lb rear springs. The base suspension cars had 300lb rear springs and the F-41 sport suspension cars had 355-360lb springs in the rear so I am not sure about that statement either. If you are thinking of purchasing a composite rear spring I would talk to Corvette Central, Mid America, Ecklers, or VBP (I bought mine from them in 1985 and still have it on the car). I think their comments would be valuable to your decision.

sounds to me like composite is the way to go. i live in So. Calif. so I drive my vette all year long.
Not looking to do any racing, just want good handling for daily driving, winding mountain roads and such.
Heat shouldn't be an issue, my next step is hooker side pipes in a couple weeks. That should keep the heat away from it eeh.
Thanks for all the input.
