I am thinking he has heard (and used) them all after driving that around!
Leading evidence: 'Use ) them all' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'guy' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace handling and performance' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

There's probably a guy with an Acura somewhere looking to get it back now...

Suggestion
The combination of spoilers, drag, and lift will change your handling and performance.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

You can't install a roof spoiler without adding a front splitter to counter balance the added down force..... oh, wait..... er..... sorry..... wrong thread!
If you like the looks, do it. It will change the air flow a little as it comes over the back but not to the point that it will be noticable.
Turn it around so the opening is facing forward.. thus reducing drag and adding a little lift in the rear... since that wheels have to be ballance due to physics, that means the front must then be getting added down force..
its a win win !!
If you get the two basic bars for a 996 Porsche Roof Transportation System, you could mount just the rear one. With the rubber piece that fills the slot, it would act like a rear roof spoiler. To ensure you have equal downforces and lift, you could mount the front one as well. If you have nothing to carry on it, then mount 4 large CiBie headlights on the front, and an adjustable kite string on the rear bar. The combination of spoilers, drag, and lift will change your handling and performance. I just can't say how.
Notice the rear spoiler on my weiner.
no no no
THIS is the sun SPOILER

They dont effect the areodynamics and blocks most of the sun while driving...install front AND rear is advised
Add some Porsche sunglasses and stick your head out the window to see where you are going
Looks a little ricey to me... There's probably a guy with an Acura somewhere looking to get it back now... (I was going to say Honda, but didn't want to hurt Tim's feelings...)

Could do something like this.
The front sunshade-spoiler on a rear engine 1951 Tatra, which adds downforce, reduces lift, accelerates air over the car for turbo effect, and shades the sun!
(No, that's not a Tatra, that's a '51 Chevy that looks like it could be a Tatra.)
