What do you drive?
A Sport Model 370Z has what is called "Zero Lift" Aerodynamics with the Spoiler and the small Wing on the trunk lid. This means they keep the car from trying to "float" at high speeds. Nissan does not define the exact speed at which these come into effect.
A NISMO model370Z has what Nissan terms "Negative Lift" aerodynamic package. At the Higher speeds, that Nissan does not define either, the aerodynamics package with the active front spoiler and the larger wing on the trunk lid actually start pushing down on the car (downforce) to keep it firmly planted on the road. By how much, Nissan does not publish these numbers either - at least no where that I have seen.
Hope this helps.
EDIT: The link in the above post to mine steers one to a Car & Driver article in which Nissan DID define these numbers. Apparently, 75mph and 18 Lbs of Downforce on a NISMO Model, QUOTE: "
but Nissan claims all the body modifications create no additional drag and generate 18 pounds of downforce over the front axle and 35 pounds over the rear at 75 mph"
