I've had my M3 for about a month now, and I want to start adding upgrades and modify it, but I am looking to start small and progress being that im a 19 year old college student money doesnt grow on trees so Im not being cheap, I just have to work within reason. Does anyone have any suggestions of things that would be a good way to start and work my way up to bigger Mods in the future?

Supercharger, Vortech!!!

don't bother. save your money until you graduate and get a steady paying job. then just get a kit. it's pretty much useless now to buy 1 or 2 parts and install it and then waiting another couple of months to get another part and such. by the time you have a supercharger or turbo installed, your 1st few parts will probably have to be replaced.

+1, listen to him...if you can. :D

cheap stuff.

clutch stop ~$10
cdv delete ~$free-1hr labor
zhp shift knob- ~$100
lowering springs ~$250
short shift kit ~$350
pullies ~$200
streamline filter ~$70
blackout grills/gills ~$75 each.

Where there is a will, there is a way. With Innovation, creativity, and DIY you can do a lot of stuff for rather cheap.

^^^Good list Serious. I'm a new M3 owner too.... what is the cdv delete?

^^^ Clutch Delay Valve.

what is the point of the clutch delay valve? (noob question)

To smooth clutch engagement and disengagement. The CDV is screwed onto the hydralic clutch line. It is NOT a valve by definition (does not "open" or "close"). It is simply a fitting that has a smaller diameter hole in it to slow fluid transfer to and from the clutch master cylinder and therefore slows the rate at which the clutch fork moves back and forth (no matter how fast you move the pedal with your foot). It smooths out clutch operation and makes changing gears less jerky. The downside of having this system in place, is under spirited driving, and can actually wear down the clutch faster because it slips the disk onto the pressure plate. When I am driving like a bat out of hell, I want the clutch fully on "NOW" and I want the clutch fully off "NOW".

do the pulley sets actually produce a noticable power increase? Are they worth getting?
