G35 Coupe "Sport-Tuned Suspension"

Does anyone know what the "sport-tuned suspension" is on the new G35 Coupe?
Just bought a 2005 G35 6MT which supposedly came with this, but debating a new suspension as it doesn't inspire much confidence of the showroom floor.

Since NISMO offers suspension components for this car, has anyone had any experience with these or other aftermarket companies?

the G35 suspension is just suppost to have less air resistance so you can maintain velocity

i too have an 05 6mt and it has a vlsd, a stiffer and slightly lower suspension and 19 inch wheels with low pro potenzas

The sport suspenision on the G35 coupe which is only on 2005 coupe's delivered with oem 19's, is as follow's.

Same ride height as regular coupe suspension (as measured on the lot, regular coupes vs coupes with the 2005 sport suspension)

Same spring rates in front (314lbs)

24% rear spring rate increase (342lbs to 427lbs)

Stiffer shocks

Infiniti tells us the sway bars are stiffer, though we don't know exactly what was done, I have reason to believe that the front bar is different via thicker hollow walls, likely featuring about 20% greater stiffness. I don not believe that the suspension has a rear bar that is any different then the regular coupes suspension.

All coupe production, REGARDLESS of build year delivered with oem 17's or 18's has the regular coupe suspension. People get confused and think they too have a sport suspension. Reality is any coupe that did not come with oem 19's, has a "sport tuned" suspension meaning the regular coupe suspension.

When making lowering spring choices for the coupe, be very mindfull that most aftermarket offerings are not geared towards maintaining performance, they are a compromise to lower the car and work as best as possible with the regular coupe shocks. If you don't want that compromise, some 350Z based springs are a vastly superior choice.
