I realize it may not be much drag but thinking every bit helps... what do you think ? has anybody leveled out their car found found that it helps aero ? ( I realize lifting is generally viewed as hurting aero but in this case I think a neutral "wing" may offset any extra bits hanging in the wind ? .... I would only be increasing the front an inch or two with commercially available kits.

Thanks in advance for any and all help.

Since Hucho ran VW's wind tunnel for a decade, and has published about drag sensitivity to body inclination, I'd be comfortable presuming that this aspect of your Jetta has already been addressed during development.
