Pics added for springs and spacer.
I only have two of spacers which are 20mm.
As far as springs go, there are no difference between roadster and coupe.
They use the same springs but if it sits on roadster, it sits 0.2" lower but not noticeable at all.
and BUMP.
i'm kinda surprised not much inquiries for head unit...
This head unit is pre-wired for 370z so plug-n-play!
With navigation, bluetooth, and iphone connectivity, it's a very good deal.
For those who buy the head unit, i will throw the fitting cover which is brand new!
