1. As of last fall the sideskirts could still be purchased. I bought mine from Bill Jenkins. Dont know about the SVT bumpers, I am going a different route.
2. You can get *some* Energy Suspension bushings but I believe all of them, except for the tie rod end boots go on the rear suspension. If your putting on a bigger bar, and especially if you are changing rear bushings (the subframe has to be dropped) strengthen you sway bar backing plates. With you doing spirited driving, I wouldnt be suprised if you rip the OEM pieces off the car. To my knowledge there are no aftermarket front control arms/bushings. The only thing I have seen for the front is boxing in the arms. I dont see how you have gone through tie rods, I havent had to do them yet. What brand are you buying so I can make sure I dont buy them when I replace my parts.
3. Havent paid attention to MTX parts since I have an auto.
4. Read three.
5. Under the hood, trunk and in the doors can be painted to match for an additional cost.
