The monospring concept is a great one but I have had trouble with it. I installed one with my mechanic a few years ago and during the installation it got dinged or knicked somehow which led to the spring failing (delaminating) very soon afterwards (less than a year). My '68 came with a performance suspension and I went back to Vette Brakes and purchased a replacement heavy duty STEEL spring and have had no trouble since then.
I used the Vette Brakes components like our Hokie friend wants to and have everything but the front monospring underneath my car. I bought the pieces over time and the people at VB were very kind and gave me discounts on the individual components as I made the switch. They will bend over backwards as they are a quality business...

Glen is right about insulating your exhaust, it is a bad thing to do. The pipes will fail faster than they are supposed to if the metal can not cool of at the same rate.

I can still tell if it is "heads" or "tails" when I run over a dime on the road without having to radically re-design one of the best sports cars ever made.

One thing to take into consideration is what it does to other components in your car. The constant jarring and shocks resulting from a racing/STIFF suspension will cause havoc on a car with lots of plastic inside of it, not counting the body. The cracking will show up on all the normal wear places on your Vette at an accelerated pace and your body shop man will start sending you his annual calender and call you by your first name.

Be careful when modifying your suspension, you may not be able to listen to your cars CD player and you will have sore joints when you get home from a nice ride.

I can tell you from experiance, do it slowly and work with a company who will help you get the results you want without ruining your car.

Sorry for running on...

It is your car and you gotta do what ever you gotta do to make it the way you want it. Chris does make a couple VERY good points about stressing the rest of the car. If you do decide to make it a really stiff syspension, you might want to put some brand new body mounts in there also.

Thanks for the info. I agree with a stiffer suspension causing more stress on other components. I can't wait to get started on this project, but it may be postponed if I don't have a cement floor in an enclosed space to do this. I don't want to be outside in my driveway in midwinter changing a rear spring.
