Sometime on the freeway when I'm going really fast and I hit a level change on the freeway, my car bounces and I kinda loose control of the car for a second. At 130mph this really scares the crapolla out of me. Can I get a new suspension or springs to help with this? Please advise. Thanks

It's the oem valving of the shocks. If you really want it to go away, invest in tighter shocks or coilovers. The current crop of G35 coupe lowering springs, being progressive, and on the soft side will not kill off what you you've discovered. I noticed that when I reinstalled the oem sport shocks on my car that the high speed handling got really weird, something the tighter Z shocks I normally ran, never ever did. I would recommend Koni shocks or Tokico D-spec shocks (Tokico's should be out any time now) or again, coilovers. Tein Basics are a excellent choice at $800, kinda depend's on what qualities your after from your suspension.
