The wing cannot handle speeds of over 170 mph. My wing broke in two running the mile here in Miami. The car went 186mph with the wing, and 188 mph without. It lost some stability, but not much. These cars are not meant to go that fast anyway. At the next event I should go a bit faster. I will then find out how stable it is.

I understand they are not meant for high speeds, just trying to figure out what the best option to do is. Wing or no wing? This closed airport is gonna be the new racing spot in my area. Its gonna be dig races and roll races. Some of the cars are top speed cars like the c6 z06, techart tt911, hpf m3s, so i need to figure what speed to go to and wing or no wing. Less drag more top end ect.

If you are planning to run over half a mile, with the power you should be making I say no tail.

should definately be over 850whp on the low side. on rolls its break boost the hell out of it and get out ahead as far as i can. the owner of the airport is actually a big fan of the moscow 500 unlimited, where its a contolled shut down 2 mile road that they race for a mile. so no wing?

I've been searching and came up with Evo viii coefficient drag of .36 to .38 and Evo ix with vortex generator .34 to .35 . These are wing on. A c6 zo6 has .26 to .27 . So with a wing on my car it will take far more power for me to overcome the 140-150 than the vette. I wo deer if the coeffiant drag of a Evo with no wing would be close to a lancer non Evo? If so they are like .30

The function of the wing is to provide rear downforce. There will be some drag, but good drag. Without it, the rear would become very light and swing out (oversteer).

Does anyone have a link to said video? I remember seeing the video on EvoM a few years ago, but I haven't been able to find it lately.

This has been covered on the forums a few times. You need an evo 8 wing. The evo 9 wing is hollow and the evo 8 wing is solid. Quite a few people have broken their evo 9 wings above 140 or so. It's been known to destroy the trunk when it breaks too.

not like this. when he gets squirelly as he breaks and goes into the turn.

At willow i could feel my Spoiler wobbling around turn 9, granted it was a very windy day but the thing its as sturdy as it looks. On a side note after all the wrecked Evo threads I have seen , seems like the wing is the only thing that ever survives the crash; go figure lol.
