A few people where interested in the M-Sport suspension upgrade info for the 1.9ls. I e-mailed Bekkers about the setup and what their cost would be. It breaks down as follows:

(2) 33 52 1 092 576 M-Sport rear shocks 145.00 each
(2) 31 33 1 092 659 M-Sport front springs 100.00 each
(2) 33 53 9 070 114 M-Sport rear springs 240.00 each
(1) 31 35 1 091 631 M-Sport front anti-sway bar 145.00
(2) 31 35 1 091 228 M-Sport anti-sway bar rubber mounts 4.00 each
(1) 31 31 1 092 573 M-Sport left strut 260.000
(1) 31 31 1 092 574 M-Sport right strut 260.00
(2) 31 33 2 225 337 n/g (should be the M-Sport front bump stops but Bekkers couldn't find the part)

for a total of $1643.

I've gotten other prices (cheaper) from a few people in Europe (THANKS!) but after you figure in shipping/customs and such the prices are going to be fairly close.

The M-Sport uses the same rear anti-sway bar and the new front one is 1mm larger then stock. It would probably be better off going with a set of RD anti-sway bars then using the M-Sport pieces.

Based on this I decided against the M-Sport components and am instead getting Koni Sports, six cylinder Z3 springs, M3 offset upper strut mounts and JT-Designs rear shock mounts. I needed new tires as well so I went with AVS-Sports. The whole package is going to cost slightly less then the M-Sport components and should be better. Because of the Koni's it is more tuneable for sure.

The springs I am going with are because I didn't want to lower my car and no aftermarket company offers stiffer stock height springs. Based on the options (weight) in your car BMW uses different springs. I am assuming as the weight goes up the springs are stiffer to compensate for it. The springs I am getting are about 4 weight classes above what my car currently has in it. I'm hoping this translates into somewhat stiffer springs with the stock ride height. The Koni's should let me tune the car in to the springs. I'll know for sure in a few weeks after I finish installing it all.

Hope this helps,
