New Wing to Test
#341
The first short run of lower cost FRP GT-250's we did sold out instantly. We'll do another run when we have the frame rail through-trunk mounts sorted. I'm trying to get one of the prototype dual element set ups to run at NASA nationals in September. As mentioned in the other thread, the goal would be to get a single element FRP setup with giant frame rail mounts to market for under $1300, about the same cost as the production CFRP foil with little universal trunk mounts.

Unfortunately, no. It's just another semi-pornographic COT wing shot that I took today. The rest of the car matches - 525 hp LS3, 275 Hoosiers on 15x10 6ULs, etc. The front splitter and wheel spats aren't done yet, BTW.
Looking forward to hearing more about the dual element setup you're working on. I've got some fun parts coming for my own car that would be illegal in most race classes - more when I get them implemented.

Oh mannnnnnn that thing is looking MEAN!!!

Agreed - mostly. There's an Exocet builder in Florida who claims to have purchased a half dozen of them at $125-250 each over the past few months on eBay and the like. I have some suspicions about the legitimacy of these claims, but I believe there are still a few lurking deals on Craigslist in the roundy-round regions.
I've got a show wing here at the shop. It's quite a bit different from the race ones, but I'm thinking it could be upgraded with some two-part foam and a couple of spars. Once I have a few things worked out, I'll post details.

FYI, we've had a few requests for these mounts lately. So we're running another group buy on them. I know there are two orders in already, they just aren't listed on the site yet.

I haven't made any progress on turning the show car wings into functional ones, but I've got ideas. Soon.

Not exactly the update to this topic I was hoping to see Keith!

He's been in Saudi Arabia, else I'd have him funnel them all to me for resale.

The lower mount that comes through the trunk lid is a piece of ~1"x3" angle that bolts to the trunk rain rail, and it attaches right on top of a reinforcement welded in from the factory. It's already a really sturdy spot, but I have a large fender washer on the front bolt that sees the pulling forces.

The EP airdam with undertray back to the subframe seems to get rid of quite a bit of lift. I'm running the wing at pretty close to 0°, but I took it off for the last session of the weekend and the car was significantly slower and harder to drive. The undertray is also adjustable for height behind the airdam, but I haven't had time to play with that yet.
Fwiw, my top speeds at Putnam park were higher with the wing. A splitter would be nice so that I could crank in some more wing and have more overall downforce, but the fact that I'm running the wing with so little angle isn't really a bad thing with 130hp.

Same things we found. Properly configured EP dam makes net downforce. Enough to distort a pretty stout piece of plywood and bend mounting points at 135mph on Crusher.
Also found that a properly set up high mount 2D will have no net increase in overall drag from a stock trunk lid and tail. Not surprised you actually found a gain with the 2D. My data had about 1.5mph of "noise" so I called it a wash. I did have data points indicated a slight gain in top speed with the 2D but I couldn't repeat the same percentage gain when I did a control the second time.
This stuff is great for the Miata track guy that doesn't have a lot of power to play with. Where we found the big gains in drag was with the splitter and cables hanging off the nose.

Update!
We had one person bail on their promise to buy a set of these mounts. So there's one set left for an NB. I don't think we'll be doing another run, so if you want a set here's your chance. Once this set is gone, they're gone.
No, they won't fit an NA. The angles are wrong.
