Long, flat undertray on the 280ZX V8, connects to the bottom of the front spoiler and goes right back to the front of the engine and right out to the sides in front of the wheels. Looking at it from above it's a T shape with the curved head of the T connected to the spoiler, it's around 1.1m/43" long front to back. Bit hard to take a pic of it fitted so lots of description
The question is, should the back of the tray stay flat or should say 75mm/3" of it be bent up or down? Going on what a lot of modern cars have I've bent the back down to about a 45 degree angle, assuming this will help extract air from the engine bay and not have any negative aero effect although the result is an upside down hatch spoiler shape there which may by itself generate lift. But of course there is air flow on both sides of the 'spoiler' which I assume changes things.
In all my aero research I've never seen this point discussed so does anyone have some good info that they could share?
