Fran, They are of course worth as much as you can get for them. But I would think you have about $35 worth of 6061 and about 2 hours worth of labor if it is all done by hand one set at a time. You do good work and I live in Calif so lets say $75 hour shop rate. Call it about $200ish the set in cost for a one off. Mark them up 10%, how about $225 or there abouts the set?

If you make a lot at one time, maybe a little less, but I have no idea if you intend to recoup your R & D or how much you have into that.

If I'm way off, I don't mean to insult. They do LOOK like they are exotic and expensive.

Oh... and I have some that are very much like yours. They make very little difference if any at all. Nothing like the rear spoiler. It does make quite a bit of downforce that can be felt above 80 or so. I like them because they make for a balanced areo look.

I suspect the real effect of the front canards is a couple of dozen pounds of downforce at 100 or so. Maybe more at much higher speeds. I'll never know. Anything above about 125 or so on the road, and in a corner, isn't really cool and the time spent at 150 or so on a track, and in a corner, is so little that it is really hard to quantify any performance gain.

Besides I don't drive good enough to tell anyway.

Still saving for the P car. Gonna be a couple of years though.
