downforce games
You are definately correct
But its impossible to argue with forum tun4rs so... lol
Now if only I could find a front splitter/undertray for my 5 id be set.
This looks like it might work for my car, but i would want dimensions and such before i decide:

It's so refreshing seeing these kind of threads after seeing so much BS.
aero, realistically, is aero..
you see lots of DTM cars taking the shape of closed wheel and open wheel cars....
the big aero inefficiency on our cars, is the underside... the car needs a proper flat bottom with a rear undertray.... the pinch point of the undertray is very important.... cars like the f360, f430... they try to create tunnels like the older GTP cars had....
get dive planes on the front... help air to evacuate... and flatten the bottom of the car..
the most important thing is to create a good aero platform... you want to balance the entire car... we would spend lots of time doing steady state speed runs down the straight to measure damper travel to confirm the amount of downforce on a car....

the person that makes them for evolutionary can custom make you whatever dimensions you need. no more excuses!
iunno how comfy you are with doin' body work dave, but i'd say you should cut that bumper at the "line" going all the way around (the one that goes across the license plate area) and move the diffuser "up a notch"

That would be a job and half. Actually I was thinking that since it is impossible to keep all the air out of that upper area it might benefit from leaving it open to let the air pass back out. Remember, it is only like that because of APR's wide body kit. On the USDM EVO8 it fits flat all the way around.
Is he on here, or do i have to get in co ntact with evolutionary first? Id like to know what goes into the construction of these, and how much downforce they can hold.

and then for any flow that squeezes above the diff etc. you can poke some holds in the rear... mabe 3 on each side. this will give you a lotta df in the back without presenting cross sectional area to oncoming flow like giving your wing more angle would.
The holes are so ugly!!! I am only willing to do so much and nothing at the cost of UGLY. haha
Fatheroftheevo, if you just want an undertray and not a splitter this material I am using would work great, you could fabricate those kick ups into the tire area if you felt the need.

I am certain that this material will withstand a 2" splitter. We are just trying to drop the drag on the car, so the undertrays we are making tuck in behind the front lip for the least amount of drag.
except this is exactly analogous. notice how the fenders stick out beyond the body of the car, that creates an acceleration in flow over the "hump" on the side of the car.
