Gotta ask - why not install the complete kit? 
Just a tad.........brabus springs??? sooo does it lower the car at all? lol
KW makes a set of coilovers for the car. I have not tried them, but with my experience with coilovers on my lexus, it does make the car stiffer, but everything is adjustable to the way you like it (height and stiffness)Who makes coilovers for Smart? Who has them and what do they think of them. Is the ride softer or stiffer, cornering etc. Thanks
Pictures or it didn't happen.Finally installed the Brabus shocks/struts + H&R, ride quality with the factory 15's was lousy at best, especially since the road conditions here in OK are akin to Nairobi in parts. Front install was the most taxing thing i have ever taken on (sigh).
However, got some Darwin 15/17's on it with Toyo P4's (205/50-15 & 215/40-17), HUUGE difference, i'd compare the ride quality to the stock passion suspension / 15" setup that came with the car. Love it.
NOTE: With the slightly larger tire sidewalls (lack of tire choices in an all-season tire), this thing looks slammed, i'm getting used to the look and no rubbing thus far, glad all the research worked out. Thank you SCoA & Randy Zimmer =)
