This is simply about what you have. Nothing to do w/ opinions or preferences. Although it was inevitable that people were going to voice there opinions. Remember, it's not a pissing match and to each his own.

I agree. The "tail" was never a cosmetic enhancement. Cars equipped with a tail and associated chin spoiler seem to be a bit more stable at freeway speeds. You can feel it amidst that cross-blast in front of a big truck when passing.

For a non-track car I like the clean lines of no tail, but if I was tracking the car a lot I would put a tail on it for sure from a performance stance.

In the early years of the 911...pre RS/RSR, The factory was reaching unbealivable speeds at LeMans in stock bodied coupes. ~180mph IIRC. That takes *****, but great effort was made to get the cars as low as possible.

Just to totally hijack this thread, I was watching an in-car lap of LeMans with Derek Bell in the 962(?) from the '80's. It is completely insane how long the Mulsanne Straight was before they chicaned it. I cannot imagine doing it without some downforce though that would slow the car a bit. 180 in my car? Yikes!

Thats a fun video. He really pours it on once he gets in sync. The fun part is when he gets passed like he's standing still and says "that's jacky(Ickx) on his qualifying run"

With the Turbo it also provided the room necessary for the intercooler. The stock lid would not close over it. The lip being present on the rear and both sides of the spoiler `tray' collects more air to be drawn through the intercooler and engine compartment.

Hey Ed, When you were running "tailess" were you also without a chin spoiler? I'm about to delete the tail but plan on keeping the chin spoiler. I'm curious what the results will be with that configuration because I know both spoilers work together.

Very true. the early turbo without an intercooler had a dedicated tail often confused with a carrera tail and looks great on a wide body. The later turbo tail is a necessity in several capacities given their capabilities. Also, there are two different turbo tail "lips" that form the scoop; one deep, or taller, and the standard.

No, I had no chin unit either. The accepted wisdom is you can run chin only, but not tail only.

Kevin,

I wouldn't run w/o the tail and just the chin either, it's should be both or neither.

Ed,

Agreed w/ your statement and testament to the tail helping the downforce, is the same reason why even the new generation tails deploy at certain speeds.
My 09' deploys @ 50mph.

Actually, it is reduction of lift, instead of downforce, to be specific.

I ran my cabriolet with just the chin for years - helped keep the front planted at 135 on the back straight - made a big difference at the higher speeds
