Also, am interested in used wider wing. My wing is currently 50" wide, would like to try 55"-60" wide.
Please let me know if anyone has used set of taller uprights or wider wing to sell.
Thanks

I think you would be disappointed if you knew how little effect a 5" wider wing would make in terms of downforce - my rear 55" wing produces max 250 lbs of downforce at 130 mph.
Also, keep in mind that your wing base and wing are meant to work together to accelerate the flow under your wing for maximum effectiveness. By raising your wing, you are decoupling that effect. The key aerodynamic challenge on these cars is to reduce front lift at high speed - but by raising the rear wing, you are making that worse. I have found that the best reason to raise the rear wing is better rear visibility.

Would you not gain more down force with a higher wing as it would be in cleaner air and therefore be more efficient . My experience with wings is limited, but I run my wing at roof top level and set at only 2 degrees. Find that this is best for minimum drag and sufficient down force. While still in test mode, working to log top speeds at different angles / drag effect.

To maximize downforce, what you are trying to achieve is the lowest pressure on the underside of your wing. The ducktail wing base is meant to work together with the underside of the wing by acellerating the flow under the wing. Higher velocity means lower pressure, which means more downforce. There is really no benefit of raising the wing into "clean air" because the air, a foot or so above the deck lid of a Porsche Cayman is not disturbed by anything but a possible roof antenna. Without a good downforce measurement, you are only guessing in terms of your wings effectiveness of creating downforce. Measuring drag is relatively easier because you can look at top speed.

I have the wing you may be...
looking for. It is from Mirage International in San Diego, CA
60" wing with end caps and a Gurney lip. I bought in last February, and have since taken it off the car, a 1997 Carrera as the car is being sold.
This is the first time I really looked at the pics. The mottled finish is some light reflection, or? The finish on this wing is awesome. I'll take more pics for any interested party.
It was semifinished when I got it and my tech drilled the proper holes for 0, 3, 6 and 9 degrees of down force. He also added the Gurney Lip, and we had the end caps powder coated red, and the uprights anodized to address any potential corrosion.
I want $1,200 for the wing + shipping.

Downforce?
We read, "....my rear 55" wing produces max 250 lbs of downforce at 130 mph." I am just curious as to how these numbers were obtained? In a wind tunnel with scales?
In contrast, yhe Porsche 993 RS Club Sport, according to the Factory 993 RS & RS CS Bulletin, produces a mere 160 Lbs of downforce, with 9 degrees of down angle on the wing, at 160 mph.
To produce 250 Lbs of downforce at 130 mph, that must be a monster wing, with only 55" lateral measurement, the chord must be monstrous.
