Some of the projects we've taken on this past year have dealt with other platforms, so this will be a place for us to share that stuff with you guys.
One project we've been excited to be involved with is the Jager Racing STI which, after winning the 2014 GTA and SLB series for Street AWD, is under a full overhaul for more power, more aero, more tire, etc. to jump up a class to Limited AWD for 2016.
The hood louvers for this car were developed using the same focused testing as we did for the Miata/MX5 chassis. This first set was a custom one-off for this car, but we now have production kits for both the 04-05 and 06-07 WRX/STI as a result of this project:
This was my pit neighbor at streets of willow a couple week ago. He was showing off his fancy air ride suspension. cool car. I'm sure there's an insane amount of money in that car.
Track report from Jager Racing following GTA/Superlap Battle:
"Let's just say the louvers are working amazing! Yes it was only 60 degrees but wow let's just say that the car would leave the pits at 200 and after a warm up and at the end of a hot lap the coolant temp was at 130-140!"

As silly as it sounds at first, it's an interesting idea. The forward edge of the hardtop would be a more effective vent location than anywhere else in the interior that we often see vents placed such as the rear window.
But nobody is going to be cutting their hardtop up, and 5 lbs of downforce is some very high-hanging fruit. For perspective, our endplates for the APR wings bolt on with two bolts and can have well over 20x that effect.
Switching from APR to Singular endplates with no other changes yields 100+lbs of downforce?
Depends on many factors specific to each car and their current config, but yes. 25% improvement in pressure gradient between top and bottom of the wing actually measured. Of course without a wind tunnel and other bits far above our pay grade we have to work within estimates and calculations, but depending on what your current wing is producing, that 25% could indeed be 100 lbs of downforce.

That's the end goal for most who buy the endplates - most often they are currently running several degrees of AoA on the wing to achieve their overall aero balance, and switching to more effective endplates lets them drop those several degrees out, make the same net downforce and lose a big chunk of the drag they previously had from the more aggressive wing angle.

Yep, I was literally just quoting something you told me in another thread.
