Meh...it'll rub out.......










glad to see he had a HANS device also. he would have major neck injuries from impact...sheesh. glad he is okay.

this video is for all the wingless evos around.....................thats why i keep mine on......good to hear the driver is in good shape.

He modified the mounting of the wing and thats why it failed. He had that wing on the car for several track days prior then modified it and it broke after just a few laps in the new position. It was never designed to be mounted above the roofline in direct air the way he had it.

I don't think his cage had much to do with the fact that he walked away. It was not a concentrated impact or direct. It was glancing and distributed down the entire side of the car. He just had an Autopower bolt in cage. The A, B, and C pillars are fully intact as well as the rockers and the roof.

I was quite waiting for someone explaining it that way because of my bad english.
A lot of people are saying " yes rollcage save his life at 150MPH "

But even people who are tracking at much lower speed without rollcage are fool.
It can be much worst hitting head to head a concrete wall or taking a pole sideway at 60mph than the Sti pilot accident.

Not saying the rollcage in that STi didn't help, it did help holding the doors from crushing the pilot while it was "sliding"

Not too much a fan of carbon doors either. **** just disintegrated.

An Aerodynamicist/Data Engineer has his thought on the cause:

Guys with carbon trunks, really need to reinforce them! or make chasiss mounts. You know all the carbon trunks out there in the market are wetlaid and they are way too soft to handle large downforce from a wing at high speed, you can push it using your finger and see how soft those trunks are !

This is the original setup he had for over 3 years on the car.



This is what he had modified to the wing, and crashed 1st day after 4 laps with this setup.



He stated that he is not blaming APR for this failure, and suggested others : "Let's keep it civilized and realize we can all learn from this. I don't want anyone to suffer the same fate we did and understanding the effects of this modification should help anyone who's considering such a modification to their wing."

Dont flame me but from my point! IMO the wing had little affect... his front tires hit the edge of the corner (i dont know what they call those things they drive on) and it just hooked the front tire enough but the wing definitly created less downforce to allow the car to run sideways and roll!

Shouldnt have bought a SUBY! Or modded his wing but he probably has the money to fix it or the sponsors do at least

Does anyone have the link to the Evo that slid sideways at 170mph on an abandoned airstrip in England?

A guy in England was doing top speed runs in his 600hp CT9A. He felt that removing the wind may give him a few more mph. When he let off the throttle, the car slid sideways without flipping.

There was a thread with a video link on the boards a few years ago, but I can't find it at the moment.

#1 cause of the crash was the driver. He clearly didn't notice the wing failure or if he did, he did not anticipate what happens when you have less rear downforce and lift off the gas at 140+ mph in a turn. I've pulled a similar move in my car - fortunately for me it was on a wet track at ~45mph and all that happened was that I looped it on the track.

Stupid comment because wingless are wingless.

When you loose you rear wing in a turn, it is a different story. Air flow are broken and you loose the down-force on the rear. It will have an effect like "slamming the front brake" and in a turn no good.

Wow, I knew this would pop up here eventually. Phil is a good guy and a great driver. He's been at NASA MA events for a long time now.

I didn't bother to read all of the comments above but I'm sure there is a mixture of people mouthing off, people throwing in their assumptions, and probably some seasoned drivers who know what they're talking about.

With that said, this was the one event I missed this year so far. That is my exact line up those esses and it BLOWS MY MIND how much the spoiler makes a difference. I, like Phil, have a GTC300 wing and I, like him, have raised it to above the roof. I still have the stock trunk though (and I've got a lancer, not an impreza). I drew and fabricated my own risers that were an add-on to my wing. I've noticed considerable grip increase going up those same esses. Now... phil comes in at about 10MPH faster than I do because of his rubber and power, but I watched that video over and over and that's the exact same way I take that turn every time, every lap, every day. Wow, coulda happened to me!

Lesson learned - check the wing. Guess what, I went out and looked at my wing as soon as I got home and guess what I found? One of my loctited fasteners from the bracket to the wing was missing!!! It must have vibrated out. I'll get that fixed and keep a good eye on it before I get out to NJMP next month.

If there's any question: The wing ripped off, he didn't notice and didn't slow down. Not as much downforce in the rear and high downforce up front without warning = whoa, car wants to oversteer A LOT! Then it all happens in the blink of an eye. I'll keep my eyes peeled in the rear view from now on. Maybe even add some cables.


FYI - for any of you drivers who are really interested in the details here's us talking about it on NASA (with Phil actually involved): http://www.nasaforums.com/viewtopic....&sd=a&start=70

Here's the failure that caused it:

Dont forget to check your carbon trunk too if you happen to mounted wing on them !
Alot of flexing can come from a weak carbon trunk, this can cause wing to move side to side.
