I have a 2011 G37S Coupe and Im currently in the market for some Lowering Springs.

Can someone tell me if the H&R kit fits the sport model?

I have read on item descriptions that fitment is for coupe models w/o the sport suspension.

 

They'll work on the S model.
Might also look at Tein S Techs, they drop the same as the H&Rs (the H&R data isn't correct, they drop deeper than 1.4/1.5")
Here's the S Tech sheet

And better yet the Tein Basis Coilovers for just over $600 will get you the exact height you want (up to 2" drop) and won't compromise your OEM dampers.
