I too like new technology overall, I am always interested in new ways to do things as well. That said, when it comes to the tubular front end stuff, I get the feeling that it is more about being different than being better. IMO the original Mopar front suspension was/is pretty good, very durable and relatively easy to deal with. I do not personally believe that a CO front suspension is necessarily "better", I recognize there are some space advantages with going CO but I am concerned about some of the engineering of some of the kits. My concern is that some will buy these kits due to the "bling" aspect without understanding what they are going to end up with.
Every car manufacturer has spent considerable amounts of money and time to develop things such as suspensions, while I am not saying they are perfect or not without fault or able to be improved upon; I am saying that before you dive in and spend a lot of money you should understand what you are getting and what the overall result will be. Sure a CO system does give you the ability to raise lower the front end by adjust the shocks or changing the springs and they do offer more flexibility in "dialing" in your front end though spring selection, but is this something most will ever do? My main concern with many of the CO systems is the support of the CO shock up front, some of them are a bit scary and if the car is painted and done and one breaks loose or cracks then you have bigger issues.
I am going to put a CO system on my 70 RR because it has a tilt front end and it pretty heavily modified already, but in my 70 Challenger, 73 Cuda and 71 Charger I will be keeping the original systems for simplicity sake. Sure, I will (and am) using good shocks and other front end components (like Firm Feel stage 3 boxes, close ratio arms, etc) to make a good system even better.
Each to his/her own; your car, your money....
