What's your favorite TAIL?

Why Heavy rubber on the Car ?
Why did Porsche put heavy rubber fon the lips on the SC and Carrera tails? Really seems a strange decision to select that material.
Don't recall any other car that uses rubber for a very big exterior part on a car

Whatever the tail, duck, carrera, turbo etc... it does help combat lift, and you do need one in front to balance the one in rear. BUT, none of these provide ANY downforce, this is a fallacy. The only way to actually get the air coming over the top of the car to push down, is if the wing is postioned high and beyond the rear of the car. Cup cars and Jack Olsen's fabricated wing are so, look at his pictures a few posts back. I learned this from a guy who has been building and racing only 911s for 30 years. Therefore, pick the wing you aesthetically like...
Aesthetically, I like the "pure" lines of no spoilers or wings. Functionally, I like the aids that spoilers and wings provide. So, I swap parts on and off my SC a lot. It's a bit more work, but the stability of the spoilers at the track is worth it.
Just my opinions...

My opinions:
- Street car (no track): No tail ...aesthetically the cleanest and most attractive. And the tail's aero benefits are moot on our US streets.
- Pre-SC: no tail for same reasons as above, but even more so since the more slender body looks odd with a tail, even a duck.
- RS-look: if ya got the flares, ya gotta have the duck tail!
- Track car of any vintage: Carrera tail ...not as large as the turbo tail and much better looking than the duck (which I really don't like at all unless it's an RS body). But the bottom line is functional: Paul Frere outlines the significant reduction in lift that the Carrera tail (reduces to close to zero lift) and ducktail (significant, but less so than the carrera) offer at speed. Stability is paramount on the track ...not to mention the tail makes any track car look more "purposeful."

For a street car, I like the looks of the duck the most. My narrow bodied Targa had a turbo wing from the P/O and it looked too bulky for the car, plus it was pretty heavy. I replaced it with the 3.8 RS wing (the narrow version from Getty) to see if it performed better than the turbo wing. Except for it being lighter, I didn't notice much difference.

ANY tail (Duck, Carrera, or 3.3L turbo) will significantly aid in engine/oil cooling as it changes the engine grill intake from a low pressure zone to a high pressure zone. This is mandatory for any track work.
That said, I have had a duck, early turbo and sans tail lid. I like the duck the best.
