I was wondering if someone could tell me if which one they thought was better (listed below) for 20" wheels without having to mess with camber/toe/etc:

1) Would the drop rate of a 350z tein spring be the same for the G35?
2) Should I go with the S-tech or H-tech?
3) Which one is better for daily driver?
4) Is alignement still needed with a drop less than 0.7" and how long do stock stuts last or do I have to get new struts to?

350z S-tech
350z H-tech
G35 S-tech
G35 H-tech

THANKS!
