I have a 2009 G37x which has too much sway and not enough dampening in the OEM setup. I do not want to lower the car. I have decided to go with Hotchki sway bars and end links and would like to add new adjustable sport shocks. Which ones fit a G37x? It seems like I will be forced into coilovers to do this and I'd like to avoid that. I won't track the car and just want better 90 mph handling on the highway. Koni? KYB? Bilstein?

Lifelong BMW / Porsche / Mercedes guy switching gears and trying a legit RWD/4WD Japanese sport sedan. Early impressions: More stock power, less refined suspension great build quality. Thanks for letting me lurk in your club / site.

 

I suppose those 20 inch have something to do with the less refined suspension. Did you buy the car with them? I would wager going to an 19 or even 18 inch wheel would help.
