Oh, you just reminded me, if you are going that low, you may want to consider shocks/struts that are designed for lowered 3's too. That much difference from stock and the OEM's are liable to wear out much faster than normal.
And, the s-lines are a stiff ride. Not much spring between you and the road. Aren't you afraid your records will skip??

 

lol.. what are records?? lol jk!!

i was told that today actually, about the stiff ride, and my old civic was like that.... slammed and i felt every bump.... but i like that feeling.. lol, it keeps you awake!

and only use my mp3 player, with the aux. jack.....

 

Shouldn't be a problem. I'm running 215/45/17's with about the same drop as a Prokit (Tein Basics) and I have no problems yet.
