Hey, welcome to the board! Always glad to have see new faces on HAN.
Before we begin spouting out modifications, I believe you should first take a look at your car and decide what you want to do with it. The first rule of thumb in modifiying cars is this:
Know where you want to get with your car and how you want your car to operate!! I can't stress that enough. Too many people start spending money left and right on modifications and for various reasons overlook key items or requirements that would either keep other modifications working (i.e. built engine with high boost) or keep the car in one piece and safe (i.e. upgraded brakes on cars that see drag use, heavy auto-xing, road racing).
Know what you want to do first, then work to get there.
Having said that, let's analyze four different aspects of the modification scene.
Roadracing/Auto-x: This area is open to a lot of options. First obtain your membership from the SCCA (Speed Freakz Program) or NASA. Get a rule book. Find where you'll be most competitive. (I run D-Stree Prepared in SCCA for autocrossing) Go from there. Various levels require different items/modifications, so I can't say specifics. Some specific items to think about though are lightened interior, helmet, brake ducts, roll cage, fire supression system, and a lot of spare parts. Your car will see
much more abuse here than anywhere else. Suspension tuning is a must, along with good tires to keep you planted under sharp cornering.
Drag Racing: Strip that interior. Get your weight down. Start thinking about forced induction, and prepping your motor for some high boost. Lightweight seats, lightweight wheels, drag slicks, heavy duty clutch, lightened flywheel, a good set of brakes that won't fade on you, all of that. Also start working on reaction time, learning how your car operates and responds.
Show: Show focuses more on interior/exterior than performance. Clean your car good inside and out, then focus on the parts that need the most work. That may be rust spots, paint jobs, cleaned engine bay, shampood carpets, etc. Throw in a heavy duty sound system to impress the judges. Start thinking original. Must be original. Eat original, speak original,
BE original.
Daily Driver: Simple bolt-ons work best here. Aim for tires (if enough $$, rims) first. Nothing matters if you don't have good rubber on the ground. Next go for Intake/Header/Exhaust to get your engine breathing good. Treat your car to a more aggressive stance with lowering springs/shocks. Don't cut, for the love of God don't cut!! A simple system, consisting of upgraded speakers, head unit, at least one sub and amp should take care of good sound. Always work to keep your car clean too. A dirty car doesn't do much, even with thousands of dollars of modifications put into it.
I hope this helps pointing you in the right direction. Good luck with your car and don't ever forget HAN! :thumbup: Keep us updated!
