I have a '83 SCarrera (3.2 Euro engine) that is primarily a track car. I'm torn between two choices, the classic duck tail and a 3.8 RSR wing that has been sized for an SC body. You can see it here:

I love the look of the duck tail but I am not sure how the RSR tail will look. The normal one usually looks too large on an SC, but this one is scaled down a bit.
Performance is another issue. Since its a track car, performance is crucial. Is the extra downforce of the 3.8 wing significant (and necessary) when compared to the ductail? I am using the stock chin spoiler on front, at least for now. I drive in DEs, usually more technical courses versus the 'fast' tracks. On the local track, although I am not there yet because of ability, the instructors seem to reach top speeds of 120mph to 130mph for very brief periods in the straights. Fastest sweeping turns are at about 80mph (my speed, not the instructors).
What do you guys thing about both the look and the performance benefits of the larger wing? Which would you choose?
