I have done a lot of research on suspension, and I have been on AST coilovers with Hipercoil springs.
Now I have been on this setup for a while and it's been really good but then I've been doing research on what I can do to better my suspension. I ran across this site.
www.swiftsprings.com
I looked for more information on it and the reviews I found on them were nothing but positive. So I went ahead and contacted them.
When I contacted them and they told me the advantages of the springs, and half of it was pretty technical so I'm not going to regurgitate and mess up the information given to me. They did however, tell me that AST is now a distributor for their springs, and on certain kits even come with their springs.
So then that made things way simple, my coilovers came with the Hipercoil springs so they have something to compare them to. So I went on to contacting AST themselves. Anyways they also told me that they prefer the Swifts over the Hipercoils, but I guess the Hipercoil name is bigger. And I purchased a set. The exact same rates and lengths.
Now I know you wouldn't expect springs to make such a big difference, but it was interesting how durastic the changes were. The springs felt much more compliant, or I think smooth would be the right word. The spring rates are supposedly more precise and everything but they it's not like Hipercoils are off on thier spring rates either. The difference was so durastic that I had to call Swift springs again to ask them wth is going on with your springs, and they told me that because of the compliance of their spring they consistently keep tires cooler because the tires are constantly contacting the ground while other springs skip over uneven surfaces on the ground, and info like that cannot be seen on a spring dyno chart. In fact they are big in many forms of racing including Nascar, and ALMS.
Anyways I just wanted to pass the word around to see if anyone else has had experience with Swift. It's weird that I have not seen them around more often. Im sorry I cannot give any technical data on the springs because for obvious reasons I have no spring Dyno or anything of that sort. I know I found something online somewhere where a swift user tested them out. I will look for it.
