525i touring wagon self leveling suspension
 

I have a leak coming out of resavoir that is connected to the shock/strut. It has a rubber seal on the bottom in the center of the resavoir. That seems to be where it is leaking. Can I get a rebuild kit? Can I bybass the entire self leveling system? Is their a after market shock/strut that can replace it with?

Touring rear suspension
 

It's been a while, but I replaced the standard rear shocks on my 99 528iT with Koni adjustables from Tire Rack, along with the front struts as well. As I recall, these were the only aftermarket items available for the Touring chassis. The reason for this is that the rear shocks are located at a different position at the top (wider, compared to sedans) for a more square design of the inside luggage area, therefore the shocks are longer. When I did the upgrade, I also replaced the springs with H & R (also from Tire Rack - I believe) to create an aftermarket "sport" version of the car. It lowered the car to a better ride height as well, approx. 3/4" all the way around.

One thing to consider, this set up amplifies the inherent negative camber of the factory chassis, so even with moderately sized 235 x 17's, it loves to eat the inside of all four tires - it's one of the few negative trade-offs for sports car handling in a larger car. To slightly compensate for this wear pattern, I always used a non-staggered wheel set up, so I could rotate tires both front to rear (less wear in front that rear) and remount the tires once in a while so that the inboard side went on the outside.

Hope this helps.....

If you research it is much easier to fix the SLS on the touring than converting to a regular spring suspension. The SLS is a very nice suspension system, just my 0.02 cents
