In Reply to: RDSport vs. Racing Dynamics sway bars? posted by Patrick FitzGerald on April 21, 1999 at 12:22:39:
Racing dynamics was desgined by some italian guy (the original one). When electrodyne (or whatever they are called) imported/marketed their products, they owned the copyright on the name "Racing Dynamics". When the orignal Italian owner/engineer decided to do this on his own, he found out he can't legally use the name of the company he created in the US. So for infringemnet problems, he renamed the stuff RDSport in the US (but it still is Racng Dynamics in the rest of the world).
I'm not sure if he changes the specs any (as compared to the original design), but some people don't trust electrodyne as much as the original RD maker (who is now called RDSport).
Hope that helps,
