What can you add to an BMW M3?

Q: I have a 2004 BMW e46 M3 coupe. I added a lot of stuff to the interior and the body so it looks great. But now only thing I have left to do is to add stuff to the engine. I am thinking about definitely adding new exhaust, intake, blow off, powerchip and other minor stuff. But for the major part, I want to add like stage turbo, twin turbo, or a supercharger. I know this would cost alot but which one would be the best thing to do? I am looking for great performance with the car. Also, is there anything that you can do to make the car handling even better? Thanks.

A: As for performance, go with the twin turbo. The supercharger will tear your engine to pieces, and the turbo, though great, has some lag. The twin turbo will nearly double your hp, and has no turbo lag. For the handling...buy bilstein suspension. They'll cost you about $1200, but its the best thing you could possible do. Make your car as light as possible...take out the spare tire, the jack, and anything else that you dont need. Also, buy some good tires and wide rims. The more tire you have on the road, the better the handling. As for tires, i suggest cooper 2xs, yokohama, nitto, or any other good street legal race tire.
