I was also contemplating decreasing lift to my 1990 civic hatchback, or at the very least reduce drag; because i wanted to 'road course race". At Laguna Seca, this little car only was able to do 70 mph on the straight

(vs. porsche 110 mph,corvette 130mph, ferrari 430 142mph).
I read both these articles...
1: confirms vent...
Browser Warning

2: says nothing really works...
Browser Warning

3: Vortex generator.. claims it works ?
Browser Warning

between all articles, we can see that I may not get the result of a decrease in drag or lift?
aero seems very confusing...So what to do???
NOTE:
I would like to reduce lift and drag, I have read "Katz" and the recommendation is to lower the car... but what about some Vortex generators.. they look like a Naca Duct???.
VORTEX

vs.
NACA DUCT
