Just to clarify a few things, the airdams are still available for $390 plus shipping, with or without foglite holes as shown on my website
www.coupeguy.com. The starting point was a 635 airdam, but a lot of time and money was spent adapting it to fit the front of the E9 and attaching to the front valence as was the original CSL airdam. Paul Cain's airdam was mounted as it was on the 635, to the front bumper necessitating drilling holes in the bottom of the bumper, a method I thought would be less attractive to prospective users of the airdam. With this method the airdam can be used with or without the front bumper.
The quality has been mentioined here, its the best that can be done with the layup methods used. Were I to use glass cloth, sanding and using actual primer paint would increase the cost to well over what most would be willing to pay. Tooling and development were expensive, but still is not what one might expect from a company such as BMW who can afford anything. Fit can be an issue, one reason is due to the variation in overall width from car to car. These were pretty much hand built bodies by Karmann and I have noted variations of over 12-14mm from one car to another. So I do try to make it clear that some adjustment or fitting may be necessary, and sanding and priming is the least that the surface will require before paint.
Any further questions about the airdam, its origin, mounting, availability, etc will be addressed, just email me at
