He has a big Wang with way more downforce. He needs it to be stiffer. I run 10k's and they are not enough. I need 11k's.

It may be because I wanted aluminum bodied ones. I'll give them a call next year to see what's up.

quick update for all z members.
i've been having conversation with FA, and i've decided to try out their 2way dreadnought pro coilover for our 370z.
but the downside to this is they need a 370z at their shop for 2 weeks for testing, unfortunately i am from canada ontario and not able to drop my car there.

Is there any volunteer that is able to drop off their lovely z for testing purposes?
if so please contact me or fortune auto.
thank you

Im running 500s with 14k/10k lowered with air cups, works pretty well, stiff, but necessary if you're lowered alot.

You have their Air Piston Lift system? How do you like it

no i have 3rd party system on all 4 wheels, they only make them for front, pretty awesome to be able to raise it on demand
