Cozy,
I can tell you speaking as one who has worked on both Saleens and Roushes (and the owner of two Saleens), that the differences are night and day. They both have different stages of performance and both use similar parts and brands such as Bilstein shocks and struts, Eibach springs, Hotchkis, (Eaton supercharger (on all models other than "E" cars which use Canton), Hurst shifters, sway bars, etc., but when it comes to the quality of parts used on the two that are actually manufactured by the company, there is no contest. Roush parts pretty much come out of the box ready to prep and paint whereas Saleen body parts require a TON of work to get them to fit up right. Plus, Roush uses injection molded plastic parts (just like OEM) where Saleen (on their older stuff, at least) uses a Polyolofin/ Polyurethane material that is very poor quality. I made the misfortune of letting a friend drive my purple Saleen and he acted stupid with it and ran it into a guard rail several years ago. While I fixed the car I just put OEM parts on it just to drive it around town (so that it did not look half way done), and when I finally got the raw Saleen body parts in I was blown away! There were pin holes all in the urethane and bubbles as well. When I called Saleen they told me that this was normal. I have since worked with several other Saleen parts from various cars and all are of this poor quality. Fitment of these cars is very lacking as well, missing bolts, pins, and please don't get me started on the panel alignment.
Trust me, your decision to tribute a Roush over a Saleen was indeed a good one.
