They are a waste of money. The drop is amazing but the front springs def do not have the right spring rate. This was the case for 09 g37x. I went with eibach springs for 07-08 g35 sedan since they stopped making it for the 09 g37. It rides beautiful NO MORE BOUNCING EVERYWERE UNCONTROLLABLY. They fit perfect I believe the only diff is the 7AT is 150lbs heavier then the 5AT in the g35. Thankfully I'm getting a refund due to the drop being over 3 inches and not 1.6 as claimed.

No godspeed gave me a 3" drop it was nice but it rode like cut springs. And all g series have the same spring rate which is 320 except 2 models which are over 400 which are the newer g37 model but the godspeed seem to be very low not to mention the springs were way shorter than eibach. But regardless eibach are progressive springs that harden over time and the godspeed were soft standard which got softer over time of its even possible. Just bad materials mixed I guess low quality steel or a quick hardening method to cut expenses after all the godspeed were $135 and eibach $295.

I'll measure tomorrow but I'm holding off on that and the aligment to get a real measurement once they settle.
