Hi all,

Who makes these for 99-04 mustangs.

Ohh cool! My photo! :D

As for that spoiler, the crew at Vorshlag made that one specifically for their car. I'm 99% sure that all the competitors in SCCA Street Prepared and Prepared make their own spoilers out of various materials. Wouldn't be hard to do.

My thoughts exactly whiskey. an ESP specific wing. Most people make these themselves.

Time to get creative

I made one from thick acrylic sheets and hinges from home depot, bunch of spherical rod ends and threaded rods from ebay and some drilling and done! I am not sure exactly how much I paid but it is definitely less than 100 bucks.

If you DD your car, be careful to check the state law. Some states are anal about these things as potential blockage of rear view. So clear acrylic sheet is a safe choice. Also for DD you would need to lower the angle of attack i.e. keep it as parallel to the road as the the adjustment range allows. For DD if you keep it like the Vorshalg guys, you may face the wrath of Drag god a.k.a mpg loss.

Now spoiler alert :) : I made one just because I felt like it. The performance gain from these are virtually zero IMO. The bending of air flow upward creates somewhat negative lift i.e. downforce but nowhere close to a real wing where the airflow underneath the wing is at significantly less pressure and hence contributes majorly to the down force. On top of that a large angle of attack (as seen in the picture) creates enormous amount of drag. Combining drag and lift and their effect on longitudinal and lateral acceleration and average speed of autocross, I would put this type of mods on the "completely-unnecessary-yet-just-for-fun" project list.

And the vast majority of people who have actually run would disagree with your assessment. They definitely do increase rear end grip and require setup changes after installing one.

That thing looks badass! Way to tall for a DD, shorten it up and it would have the cool factor to it. Of course then you would need to fabricate a front splitter also. :naughty:

I am aware of what lot of people think about these spoilers and I have spoken with few of them (national champions or at least nationally well recognized) in autocross events.
Well lot of opinions I find in amateur motorsport, is purely "opinion" based - not very scientific. I have actually run full scale CFD simulation of various size spoilers used in SP classes at various angle of attacks. And found fairly non-significant advantage even at top speed for autocross of 75 mph. Granted that I have not used my company's facility to experimentally measure the lift and drag. But this is a well established science, so I doubt my simulation results will differ any appreciably from experiments.
Note that I never said that it does not produce ANY downforce. The downforce produced by these spoilers is very small for average autocross speed to gain advantage. The lift numbers are very insignificant. I will post some results when I can. My team designs aero for Lotus F1 team. I will also show some results from my team's non-proprietory work (on full scale wings) just for getting an idea if someone does not already know. Then again spoiler vs wing data should not be compared with one another for reasons obvious.

Here you go:
Maier Racing Enterprises - Suspension Fiberglass - Hayward, CA 94541

Kind of pricey. I decided to make one for myself also. Made a template of what I want and let a plastics shop cut it out for me. Waiting for the call to pick it up. Just do some homework and you can do it yourself for real cheap. Mine gonna cost me $120. Figure in some SS hardware. All under $200 for a one off part.
