www.teamspeedmerchant.com (under Rev. 3) has great description of why the old style front end is better. I havent really run the dynamic strut to be able to tell you what to do to it, sorry.

But basically the old style is more durable, less tweakable, consistant (in its molding, the new style front ends are horrible to build. they are all molded awfully, and you have to do a lot of work to make them fast and consistant.)
