No kidding, I love my S-tune suspension, I have Whiteline swaybars as well. Never regret it and wouldn't change it for the world. =)

 

The Nismo S-Tune suspension (not to be confused with the suspension that comes on the Nismo model 350z) is a good suspension. It drops the car about ½ inch and provides a comfortable ride (that is slightly softer than the OEM 350z suspension). I believe the OEM manufacturer is JDM. The Nismo S-Tune suspension kit is very similar in characteristics to mounting Bilstein B8 shocks with Tein S-Tech springs.
