Sandy's Looking at getting rid of the 04 545I 6speed, for something a little quicker. Drove a SMG and 6 speed M3, loved it. Very close to trading, but want to know of a few tuners other than Dinan to liven it up even more. Thanks for the help guys its a Christmas gift. Jeff

alpina, schnitzer.... racing dynamics offers some cool parts...

active autoworks

I have a 6 speed M3 and love it. Like it almost as well as my old 993, needed back seat for the kids. I did not like the way the SMG shifted.. Lots of BMW sites on the web.

Alpina$$$$ AC Schnitzer$$$ Hartge$$ Dinan$. Stick with Dinan. I have had all of these products and the past and Dinan is the best for the money.

dinan would be my vote, doesn't even void the warranty

jeff this is all you need, over 400hp and will do around 200mph, it will be out in 06, i have a bmw now and i am holding out to get one of these

Evolution Motorsports

www.evoms.com shows all the makes they do. These people do incredible work and I can save you some$$$ if you want to use them. More than likely you can just buy the parts here and have anyone near you bolt them on.

The new M5 is incredible but a bit pricey for a 5 series.

Call Dinan they do BMW authorized upgrades.

for authorized upgrades dinan. I've had some of thier stuff and its good but they get TOP dollar for it.

for extreme performance check with turner motorsports (they have a VERY respetable racing resume) or bimmerworld.com
