Power upgrade kit for SRT4

Guys, first off please forgive me if I sound completely and totally naieve...

I've got a good friend that has an 05 SRT-4. Before driving his car, I honestly didn't think too much of Neons. Post-drive, though, I want 2.
He wants to make the thing faster, and keeps talking about getting the stage 2 upgrade kit, but says he's having a lot of trouble finding anything for his year, because it's newer.
I don't even know where he's talking about buying this, let alone the price range, among other things. Anyone, any suggestions?

Question 2: Whomakes body kits for the same car? I'm having some trouble finding one.

For all your friends SRT needs!

he can order stage2 from any dealership. have him get the part number off of srtforums.com. there isnt much when it comes to body kits. the only ones our there are TERRIABLE!!!!!!!!!!!!!!!!

Hey, is it cheaper to buy from the dealer or modern performance?? does anyone know off hand... it would just save me trouble

probably modernperformance, but its hard to say. the 05 stuff is still brand new, so it might be hard to find. you can also try turboneonstore.com

all the body kits look bad for the SRT-4, so go with performance mods.
