Here are some pics of two of the coilovers that we offer for the Nissan 370Z. The nice thing about these is that the height range is pretty good on these so you can either leave it close to stock height or really slam it to the ground. Check out the installed pics.
First, here are the Pro Z40 Coilovers http://www.tanabe-usa.com/z40.asp?id=22
And here are the Pro S-OC coilovers http://www.tanabe-usa.com/s0c.asp?id=6
