rear wing part 2 (with pics) ... + did the rennline gas pedal install
- thanks to comments yesterday, I re-did the rear wing adjustment attempt today and took pictures
1) remove all 6 screws - 100% not necessary but 100% easier when you do
2) by removing the forward screw, to completely take off the wing (this will be the only time this is necessary), it is now 100% easier to remove the hidden screw on the rear bracket
3) reinstall the front screw back into the wing
4) place the plug on the rear bracket into the desired position (stock, stock + 4 degress, stock + 8 degress) - yes I measured it with my new Home Depot ruler (each hole is 4 degress higher) and do NOT re-install the screw that attaches the bracket to the wing
5) lower wing down to the now somewhat floating / rotating rear bracket
6) insert 2 screws per side and tighten
Now that the rear screw has been removed, the wing position can be changed in 10 minutes as only 4 allen key screws must be removed and quickly re-installed
please see pictures

Also did the Rennline gas pedal with side extensions install today (forgot to take picture) but see below

I was able to do Heal Toe prior to the install but now it is very easy - I have pccbs
The other pedals are not necessary to install in my opinion

Paul, thanks for the great write-up. I used the instructions above to adjust my wing's rake. To further add to the conversation, the allen key head size is 4mm.
In addition, I asked a friend of mine, Joe Cheng, designer and builder of the world's fastest autocross car, about the rake of the wing. Joe has spent countless hours in the windtunnel, etc. building the Phantom, the car that devastated the USA Solo II Nationals a few years back:
Here are his thoughts on the wing adjustment for our cars:

Here are his thoughts on the wing adjustment for our cars:
"For a single element wing, there is not much drag anyway. It usually starts stalling at around 12 to 14 degrees. Doesn't surprise me for the factory to set it at around 8 degrees, since under heavy braking the rake of the chassis could easily gain another couple of degrees.
I don't know Mosport's layout, but I don't think it's considered a high-speed track. When I say high-speed, I mean tracks like Sebring, Daytona or California Speedway where part of the lap is ran on the oval. High power cars like yours would be seeing 150-160 mph down the straight, with a lot of the other corners at 100+ mph. That's when you might see some gain by trimming the wing out a bit. Even for a track like Portland, it's considered a slow-speed track and maxing the wing should be faster."

Many thanks for the info ! Just set mine at +4, I'll happily trade some drag for a bit of margin on fast bends at the Ring. Does anyone have any idea of guess on the resulting downforce at +4 resp +8deg ?

Edit: figured it out. It was the screw that attaches the rear bracket to the uprights.
