I installed the 350Evo sways from Wright Tuning this weekend. Install was pretty basic even though I managed to cross thread a few bolts. Just and excuse to get more tools! After I tapped and dyed I was back on track. I used John's very helpful install http://www.my350z.com/forum/showthre...ighlight=sway. I felt the price was a little high for sways ($545 shipped), but they have been proven to be the best as both the Schuitemaker and Unitech/Performance cars have been using them all season. I would also rather support an actual racing team than a huge manufacturer. After hearing there can be an issue with squeaking I gobbed on some copper anti-sieze around every junction and have not heard anything. I set both front and rear on full stiff settings. I just returned from an hour of abuse and am very happy with the results. The steering inputs are now instantaneous rather than the familiar 1/2 second delay that the factory suspension has. I was also happy to feel the back end come around predictably on low speed cornering. The understeer is gone. I can't wait to get back on track! After learning the limits of my car on track this year, I would say that this is the best mod I have done yet.(fly/springs/cai/cats/xhaust/pulleys/te37s/T1s)
