springs only
ofset 9-5 /11.0
im willing to roll my fenders too

 

Idk how low you can go, but i went with Tein S techs for the 350z, and cut my spring mounts down to nothing. Cut the rear quarter panels (that lip that sticks out above the tire) and i have no issues.

My fronts are 20x9 and rears are 20x10. Not 100% on the offset though. If i can recall, its +15 front and +20 rear.
