I've been glad I did springs only without struts using the Roush springs. I don't see what the fuss is about against doing so.
Screw the suspension, make it go man!
Gutted cats, 65mm TB, Greddy Emanage, true dual exhaust are all high on my list. If you can do a lot of the engine work yourself, skip all of that and swap in a 3 liter for the most bang per $$$.
