Factory Wing

[track_warrior]

I have the voltex on mine, i have it set pretty much flat so i am getting some downforce just not as much as i could do if i angle it down more. Through turn 1 @ harris hill where you are going full throttle i really felt a difference in how planted the car feels now, it just gives me much more stability and confidence. My last two mods were going from track pads, fluid, and lines to the AP Sprint kit with race pads and the voltex wing. This helped me shave my time from a 1:31.3 to a 1:29.8 i think the mods in conjunction worked very well. Dont know if the downforce of the stock wing will be the same, but i would like to share my experience that i had while adding rear aero.

You can see the angle in this pic:

to really benefit the wing, I think you need more angle, but then there s line where you just create drag and slow yourself down too...not sure what you saw was wing driven,

I think you just drove 1.5 seconds better, and braked later for sure.
Interesting feedback just the same.

Interesting thing was that a part of the track was coned off so i was letting off a bit, i think without the cones i should shave a couple more tenths. The way the wing is shaped it still creates some downforce because of how the rear is angled upward. I did the pressure washer test and this confirmed it, the water flow from the roof like would hit the wing and angle back up again a bit which means it is creating some downforce. I did feel the car a bit more stable as well through the high speed corner sections and this inspired more confidence and i could drive faster through there. It might be psychological confidence but i could have sworn it felt more planted than before.

Here is another angle of the wing

Assuming the car is being driven at close to the limit, a wing is only good if the aero is balanced front and rear. You can increase the angle of the wing (angle of attack) to increase downforce, to a degree, at the cost of more drag. Too much angle, and you'll stall out the wing, and only generate drag with no downforce. If you have too much rear downforce, you'll take away grip from the front tires (lever action over [roughly]the rear axle), and not be going *as fast* as an ideally aero balanced car. However, most drivers prefer a slightly pushy car, as it is MUCH easier to drive, and more consistent lap to lap.

We can keep going into this subject deeper and deeper if you'd like.

I bet that wing counter acts some of the high spring rate. What suspension are you running?

KW V3'S , love them so far.

[jdzumwalt]

I like that wing, but I would want it about 1/3 the height my customer would shit themselves if I should up with that.

I'm thiking something more along the line of this

are you on the stock setup? with the 7 in the rear ans 6 in the front?

Yup, im still on the stock spring rates. I havent found a reason to play with them yet. COTA in february will be the test though.

If you dont mind what are you running for the Dampener adjustments?

Bump is set at what they come from kw i think its 3 all around, Rebound is 4 clicks from full soft on the front and 2 clicks from full hard on rear. -2.5 Camber front and -2 rear

Sounds aggressive for the camber. Anybody got the OEM specs laying around? Your whiteout looks great BTW.

[jdzumwalt]

That camber is dead on for hard cornering.

to be clear, a wing must exist out in the laminar flow region. a spoiler like you have shown functions differently. wings don't necessarily create turbulent flow resulting in parasitic drag like a spoiler. so wings wont work correctly unless they are tall. im not an aero eng tho (im a mech eng). so i could be wrong
