Help, Need Quick input on Springs for '08 G35S Sedan (Auto-tragic/rwd)

[SleeperG37]

It's an extremely long story, but it involves a patch of ice and me in a rent car for about a month.

Anyhow, I've been able to strike a dealer with the body shop on replacing my suspension with aftermarket springs if I can get them in time. What I'm looking for is recommendations on springs (and possibly sources). I'm not really looking to go crazy, just reduce the stock wheel gap. I'm looking to retain the stock shocks as well. At some point, I'll be moving from the stock 18's to 19's, but do not want to get into camber kits or tire wear issues, so I'm looking for a 3/4"-1" drop with a ride as close to stock as possible (TX roads suck). Any quick help anyone can give me would be great, as I don't have the time to search.

Last I checked, the Tein H-Techs or Tanabe Sustec NF210's seemed to fit the bill, but I also thought I saw something about stock 350Z springs. Don't know if they work with my MY or not. TIA for your help. I'll post in the Suspension forum as well.
