I had these made for me from broadway static which is a sub division of fortune auto. These are the only set ever made for a 370z. They are valved for the 18k and 20k swift springs that I got over the normal ones that they would come with. They have 24 way dampening control and preload adjustment. They are also true coilover front and rear. These are for the guys that want to go very low.
I've only had them on for 3k miles.
Price:
$1200 picked up
$1300 shipped
By the way if someone is interested, I can get these rebuilt to whatever specs someone wants for a little extra. Valved for any spring rate and any length insert.
