From what I can tell there are three or four main players in the after market front end business that includes a new tubular K member, Magnum force, XV, AlterKtion, and one other, I think it was on a Mr. Norms car (Cap auto) or something like that. From what I could tell the CAP set up was more straight line track purpose built ( i could be wrong). The XV is big money but probably the best one out there, (if you can afford it) The Magnum Force requires you to reinforce your shock towers and is pretty expensive as well. They have different set ups for street/strip. The AlterK seems like the best all purpose easy to install bang for your buck complete front end kit.
However
I was going to go with an AlterKtion front end but then watched the Jay Leno piece for Hotchkis challenger. Its on the Hotchkis site and Jay Leno's garage. You can save a ton of cash by combining Hotchkis parts with Firm Feel parts and have a real nice front end. You can also do the rear included for a few grand less.
