APR wing failed last weekend at VIR coming out of the lower esses.
Phil is sore but otherwise fine. Total loss on the car.

Watch the mirror closely coming thru the esses. Catch the wing collapsing and leaving the car.

Wow, that's the worse place at VIR to crash.  Thank God he is OK because that looked terrible!

should have turned the wheel back but I guess shit happens fast at 130 also imo the car should have been in 5th gear

Phil is a pretty accomplished driver.
Counter steering he did, doesn't help when the rear passes that quick and then gets airborne.
Along for the ride.

Change your wing, just make sure the mounting and construction are top notch.

Not to mention the GT-R is leaps and bounds more stable then an STi w/o additional aero mods.

Routine inspection of the car after track use is good preventative maintenance as well.

Jesus, that's scary. Thank God he's fine.

Did anyone catch the Sauber losing its front wing at the Australian F1 race last weekend? Car just went straight; no downforce at all.

Thank goodness he is ok, that was a really hard hit.

APR's wing are really well made, and have been used in all forms of motorsports for years, wonder why it broke?

I'm sure it was just a fluke.  I race an 05 STi with the same wing.  I've got countless runs 165mph+ without issues at all.  This should in no way reflect on the quality of APR products.  In racing, $hit happens...that's why we prep our cars before and during every event.  You never know what could happen out there...its just the chance we all take when getting on track.

Glad he's ok...he is an amazing driver and very well prepared to handle his car at any speed.

Just got more info on this.  It was not a failure on the part of APR.  Phil had modified it -- "We raised the APR 300 wing up into clean air and it just structurally failed prior to me entering the climbing esses at VIR. I turned in at 148 mph and that's all she wrote."

:cheers: Your talking about in the race correct?(the sauber lost the front wing 3 times over the weekend) He didn't go straight because he had no downforce. F1 cars will still drive with no front wing, the wing came off and then got lodged under the right side tire so he couldn't control the car

Will I meant turn the steering back to the left when the car was backwards to turn it the other way to avoid the wall

Ok I thought you were referring to the initial swap.

Turning the steering wheel has zero effect when your spinning at that speed.
Momentum of the vehicle overrides any forces generated via the wheels. All you can do is prepare for impact.  
In all honesty it is better to back into a wall then drive into it head first. Much more of the car to absorb impact and the forces are spread out along the greater contact between body and seat. Rather then body and belts.

I think Phil put it best:

Quote

Yes that's correct. There are a few threads on my accident but it wasn't made clear here that I don't blame APR (I won't be buying another however). I've used the wing for 3 years as supplied and we made taller stands on our own accord. It worked great for the few laps the wing held up. My warning is not to raise the wing without considering what happened when we did it.

The wing failed because the wing support (carbon fiber piece that attaches the uprights to the blades) could not handle the increased downforce / drag of being raised into cleaner air.  A lot of RTA guys increase the wing heights, and should strongly consider this before doing so.

Aeromotions wings are rated to 200mph.  They've been there, come back, and never had a problem.  So please don't take this to problem to indicate that all aftermarket wings are unsafe.  

Here are Phil's pics:

Glad he is okay. Maybe I should get a cage eh?

As for the wing, yeah looks like they did some modifications but honestly I've seen a few APR wings break or collapse at high speed. Just look at Rhys' wing at speedway for rta last season. SNAP! A couple other wings snapped that day too.

Greg, I LOVE MY WING.. man, that shit aint flying off anytime soon I can tell you that. AM stuff is top notch.
