I can't add anything to the excellent advice you've already gotten, I just had to say...
BEAUTIFUL CAR, MAN!! I loooove SRT-4's, and your skittle looks awesome. I've been tracking the market value of SRT-4's, and they are going up! I wanted a skittle really bad, but the wife said it wasn't big enough, so I got the Charger instead. There's so many go-fast mods for them. And the cool thing is that Mopar didn't neglect the SRT4 when it came to after market mods; their Stage 3 kits *rock*. They *still* haven't done anything like this for the Charger.
My Charger has been absolutely roasted by several SRT4's. It wasn't even close. I might as well have been going in reverse.
I hear that you need to feed your SRT4 a WRX STI every week to keep it healthy. Might wanna keep that in mind.
I'd love to see a bunch of pictures of your car.... inside and out.
