I paid $290 Canadian for mine, shipped to my door.
I have a 2011 FWD, Sport, which already came with a lower ride height than the AWD. I noticed the handling was was definitely better with even less body roll than before and the car response to steering inputs faster. That being said, I also have aftermarket wheels that pushes the wheels out so they sit flush with the body 18X8's upfront and 18X9's at the rears.
The AWD springs drop the car more than the FWD but I am assuming that since the FWD Sport already comes lower the overall drop height will be the same after the spring settle.
If I don't find any reasonably priced coilovers by the end of this year, I will be looking at some heftier sway bars to make my driving experience even better.
