Sorry, haven't been on the site for awhile so I'm just seeing your message today.
anyway- i bought a set of ARK springs and they sat in my garage for about 3 weeks. during that time i convinced myself i "needed" coil-overs. so I ended up taking the springs back and picked up a set of Stance SS coil-overs. I was so exited to get them on i forgot to take before and after pics. i still need to get an alignment done but the ride is virtually the same as stock Nismo (to me that's a good thing) and the lowered look is awesome.

Hey did you decide on springs yet? I went with swifts for my Nismo!
