What JZR said about the rest of the car is important not just for performance, but can be for safety at a high speed turn like the Fontana oval where the enormous downforce at 130 mph could cause your suspension to bottom out (not nice mid-corner at 130
) unless it's much stiffer than stock.

I also have a similar CF wing to gfacter.
The stock trunk flexes or lacks support so I welded some steel bars in the backside of my spare trunk. I will see how effect this is.

This project should be done by next week.

anyone know if APR or anyone else has a higher and cleaner mounting kit for the APR wing like gfacter has? I have the same wing and mounted it just like gfacter did, but I would like to get the wing a bit higher and perhaps find a cleaner mounting kit.
Word?

it was easy as 123
For those who are running a rear wing... Does the car feel pretty stable with just a rear wing or do you feel the need to buy carnards for the front bumper? I'm asking this because I want a rear wing, but I'm curious to know if the added downforce on the rear end will "lift" the front end in a sense.. So i guess my question is, is it worth it to only get a rear wing?
I "feel" that the rear wing helps in long sweepers.
I certainly would like some data to prove so, but I can tell you that the car is better planted in elevation changes and long sweeping turns with a wing.
I have my wing set to be what I can eyeball as slight level enough to disturb the natural airfoil downforce without a wing... make sense?
I experimented with angle. My first angle was too agressive and I noticed a drop in my straight-line speeds as the drag was incresed. The angle setting now I believe is slight down by definitely shapes the exiting air to NOT produce uplift. I am gaining greater straight line speeds while remaining solid in long sweepers.
So, for our car, I should think that if Normally Aspirated, that we should set the wing near in line with the air flow as to disrupt the downward natural lift that may occurr from our top-side shape.
The entire reason for my APR GT-3 wing was from my track experience at Pahrump's 3.5 mile course. There are several elevation changes with turns and without the wing, the car would "float". With the wing the car didn't float near at all. The car felt planted. However, tweeks must be made to discover the trade-off between downforce and speed. Remember, our car does not have brute power. So, if you have a wing, setting its camber to near flat air flow - enough to disrupt the upforce is desireable.
