My '06 G sedan is currently on UN-revised Z susp., which certainly improved the handling at a slightly stiffer ride... Along with the springs and shocks, I also got a set of front and rear OEM 350Z sway bars from the same car...

Will they fit, and would there be an advantage in getting these Z sway bars installed? If not, why? If so, why?

 

I believe the Z sways are the exact same as both the G sedans and coupes thus giving them no benefits over our stock setup.

 

Cool. Can anyone else confirm/deny?

I may have a set of Z sways for sale if this is the case...

 

Tires are 90% of handling and suspension is at most 10% and modifications are hard pressed to yield 1,2,maybe 3% improvements.

Study the tirerack suspension tests on BMW here the tried springs, sway bars, shocks from different manufacturers..............a glorious 1.6% improvement.

Don't confuse the angle of steering wheel [over/understeer] or the harsh ride with improving skid pad, slalom, or track loop times.

Feels better is so subjective.
