I have the Shockwave system for the Chevelle of mine. It was bought back in 2009/10 and Ridetech was very helpful in upgrading my rear setup to a Shockwave setup instead of the regular air bag in the spring location on it.
I have also ridden in the in the Ridetch 66' and Rod's Camaro. I really could not tell the difference in how the cars handled. Am I sold on the air system? Well, not really. As stated by others, when you look at the cost of the air system to make it all work, it really is overwelming. Will I pay it? Of course, because that is what it will take. It will just take me a little longer to save any buy. I hope that by the time it get to that point, we will not be hovering above the rode. HAHA
Bret's got an awesome product. that can not disputed in my book. He also shows how to build and drive the crap out of them. I also like how he supports this board and the guys on it.
I'll just keep saving and buying. Just my thoughts.
