I recently purchased my 8 and would like to start mods. She's an '04 and I'm interested in audio and performance. Let me know if you have anything. :)

Thanks everyone

why do I keep seeing so many threads like this?

Don't be lazy. search for what you want and ask for something specific.
We do not want to blindly offer you stuff hoping you will want it.

Performance on this car is a expensive hill to climb. Your best bet for a affordable power adder is a cobb accessport.

Another line of thinking is to shave weight from moving parts: ie: lighten the flywheel, lighten the clutch, lighten the wheels.

IMHO you should spend your money on track days:
