I searched (somewhat lazily, I might add) and didn't see anything pop up about these, so I figured I'd add some potential excitement!
Tein has officially released their S-Tech springs for the Altima Coupe! I found an eBay auction that has several available at ~$198 shipped:

They offer a 2" drop (a bit more than Eibachs, a bit less than H&R IIRC).
Full specs are available on Tein's website here (you'll have to scroll down and find the model for the coupe):

Apologies if this has already been posted. For anyone looking to get rid of the 4x4 look on a budget, this is an awesome deal!
