I ordered the RS*R springs. However, Performance Nissan is temporarily out of stock. I hope to get them in a week or so. I'll let you know when I get them installed and if the handling is any better.

I also ordered some Cusco sways. The Hotchkis bars just aren't stiff enough for track duty with R-compound tires. I guess daveh found this out too.

 

That't weird becuase I was advised by several shops that the hotchkis sways are good for the track and are actually used on some of the 350z racecars. They did say that swaybars are not designed to take the roll away that is caused by low springrates.

 

All the 350Z's in GAC run 350EVO sway bars.
