You can buy the Sport Package suspension parts seperately and make it yourself. They should still sell every thing.

The Sport Suspension has these updated parts:

FRONT

• Front Springs (.6" lower)
You will have to give the dealer the VIN for a Sport Package car to get the parts number, RealOEM doesn't list spring part numbers.

• Front Struts. I believe these are the Sachs "Turbo" or "Advantage" line.
L: 31311090715
R: 31311090716

• Front Roll Bar. 26mm vs. 25mm on the normal cars.
31351091308
And two roll bar bushings for 26mm.
31351140188 (2x)

REAR

• Rear Springs (.6") Lower
Same thing with the part number. But, I did buy a pair of new rear springs (sport package) from the dealer and it was part number: 33539066887

• Rear Shocks. Sachs Turbo/Advantage
33521091630 (2x)

• Rear Bar. 16mm vs 14mm standard
33551090317

And two roll bar bushings for 16mm
33551129700 (2x)

At www.bmwmercedesparts.com (probably the cheapest place for OE/Genuine parts) - along with www.getbmwparts.com - I came up with $1,168.98 total without the front springs. Probably about $1,400 total with the front springs and shipping.

Pretty pricey. But, I see at AutohausAZ.com you can get the Sachs Advantage (Sport Package) struts/socks and save a ton over the BMW stickered/dealer version. A $290 savings. They are cheaper than Bilstein HDs (which I have), unlike buying them from the dealer and their markup.

I'd also have no issue with using used roll bars, so that would save some, just buy brand new bushings and end links.

Then you just have the springs to worry about. The factory M-Tech/Sport ones are nice and I'd say a good compromise between the standard springs and a true aftermarket spring set which usually are a 1-2" drop. Used would also be an option in a low rust area. I had a rear spring snap on me in a road salt environment.
