I love Saleen cars, but I'm not a big fan of their after-market parts and suport. I would be very leary of the Saleen after-market. I have a Saleen part sitting in my closet, but since it isn't what they told me it was, and I can't get a human on the phone, there it sits. (rear shock tower brace)
Steeda is, no doubt about it, expensive. But from experience, service is first rate. I've called Steeda about non-Steeda parts (I'm a regular

), and they have helped me out. Steeda does not make their own springs, that I know. The shocks are obviously Tokico (very, very good), cravnpup said the springs are Eibach (oh darn!). I don't know for sure, but they aren't made by Steeda, but they sure do work well with their suspension kit.
If you go with Steeda, you get:
1. Its good stuff
2. It all works extremely well together (which is the hard part)
3. Great support.
You may go cheaper finding the same parts from suppliers, springs from Eibach, shocks from Tokico, ect. But the Steeda set-up is still very nice.
Decide your budget. Decide what you want to do. (for me) Unlimited budget: Maximum Motorsports or Griggs. Works darn good, good suport, some what cheaper: Steeda. The Steeda 5 link should be out shortly also.
