What Performance Parts Should I Get First?

Gears and subframe connectors to start. Weld some aftermarket mufflers into the stock catback for sound

Blower, gears, subframes, drag radials.

Nightlife already hit the nail on the head! lol.I was literally going to write the same exact 3 thing's he did. The order in which he said them may have been different though ha ha. The car will feel and be much tighter with the subframe's sn-95 cars are notorious for body gap like doors, fenders, hood not lining up right and rattles/squeaks. SFC's will fix some of those issues. Gears will get you through the power band quicker/can improve gas mileage too depending on gear ratio/type of driving-driver you are. Everyone knows what a nice performance exhaust system will do lol . Just a heads up about the sub-frames get the weld on type, , make sure they are TRUE full length one's, and get one's from a good company that has a good reputation/makes good products like Maximum Motorsports, UPR, Steeda, etc. There's a few more company"s out there but those are known and stand behind there stuff.

Gears, Gears, & Gears. You can't find a better seat of the pants feel for less money.These cars like 3.73/4.10 gears to get you into the power band quicker b/c they are a little soft at the bottom of the tach. A nice set of lowering springs & new quality shocks will change the character of the car for the good over the stock equipment & eliminate that goofy 4x 4 look they have from the factory.

If your are Automatic transmission 4'.10's , Manual trans 3.73's! and get the Ford Racing Products gear kit as it's the best quality and no whine/howl noise!! . Motive and Richmond known for whining and LOUD whine!

I'm going to go against the grain and suggest to steer clear of the gears for now, especially if you have a manual. They unquestionably make the car feel faster in higher numerical gears because 2nd now feels like 1st, 3rd feels like 2nd, etc., but they actually don't make the car a whole lot quicker. You're talking a tenth or two actual improvement at the track, and that's depending on one big thing: traction in 1st gear. Because steeper gears REALLY start making it difficult to get traction in 1st gear, they often actually cause you to be slower if you don't have a good set of rubber to hook it up. While I love the 3.73s on my car, hooking it up on the street in 1st with street tires is quite difficult, whereas it used to be no problem with the stock 3.27s.

I'd also suggest holding off until you know the direction you're gonna go with the car. A mild bolt-on car would command a different set of gears than a supercharged car.

Other than that, I agree with the others' suggestions to do FLSFCs / suspension first. That will always be beneficial regardless of what direction you take with the car. I'm partial to the Eibach Pro-Kit springs, as they are a nice drop that still have a nice ride, and don't absolutely require castor/camber plates (it's better to have them, but not necessary). And either Tokico HPs or the Eibach Pro shocks/struts are good bargain buys.

Exhaust is something else I'd do early on, as you can always enjoy that, and it is again beneficial regardless of what you do with the car.

Other than that, I wouldn't spend money on anything else unless you absolutely knew that you won't be supercharging it. Most of the other bolt-ons are not necessarily interchangeable from NA to supercharged, so you'd likely be wasting that money on bolt-ons. Not to mention, all the bolt-ons total (CAI, T/B, upper plenum, UDPs, etc.) are only worth a couple tenths in the 1/4 at best.

Yeah I have 3.73 gears and at the track on street tires I actually ran worse than what my friends stock 1999 GT ran. I would honestly do a good tune up for the car all around to get it in healthy shape before modding. Things like replacing worn out shocks/struts and other suspension components can make the car feel amazing again.
