I firmly believe that the FSport wheels truly compliment the 3iS FSport.. Why spend money to change what is already sexy? I love how you enhanced the FSport styling. The rear 20mm spacer stance is growing on me.
Looking Great!

The way I see it is, what really is 10mm or 15. You’ll barely notice it. Same reason I went with super downs. I wanted something noticeable, if not I would of left it stock you feels.

The ride is great, the s+ mode really feels good, I only have 350 miles so I'm not driving the car so hard

Think I am sold and will make my purchase of these springs for my 3IS F-Sport. For those running aftermarket wheels, are you guys running 18s? 19s? i've always liked 19s but not sure if they will fit properly with a drop this low.

What brand Spacers did you install ?

Super downs lower the car a lot.

Curious to know the long term effects, if any, on an active suspension setup. Whenever I went with the spring route, I've usually matched them with shocks so there aren't any bottoming out scenarios.

Is the ride much more stiff this way?
If the springs aren't matched with the struts/shocks they will prematurely wear out. The oem shock is not designed to operate in a compressed state at all times. I would say if the spring rate is within approximately 10% of the factory springs, then strut replacement is not necessary. If the new spring rate exceeds the OEM spec by more than 10% then accelerated strut wear will occur. Rates much higher than stock will result in premature strut failure, excessively bouncy ride quality, and potentially unstable handling characteristics.

Looks stupid, sorry. Should call them "Stupid downs". How are you liking your 3/4 of wheel travel?
