Unless you get the SportLine springs for SLS, the wagon's rear struts does not, IMHO, properly dampen the rear SportLine.

Also, unless the roads are VERY smooth, SportLine suspension does NOT make for a very comfortable/compliant ride. Great on the track though!

IMHO, 500E springs all around (500E's have SLS in the rear) are best, including 500E front struts, and 500E rear sway bar WITH a 500E or W124 Limo sway bar in the front.

H&R's are too low IMHO and scrape everywhere.
