Freakin' tards keep doing this crap when leaving C&Cs and they will all get cancelled.

What an A$$. Just luck no one was coming the other direction. I hope he has the wrath of his club dumped on him.

Traction control was off?

This is written by the m4 driver

"Hey guys,

It was my car that was involved and a mistake was made. There were no intentions of doing anything out of the norm. In fact, you'll notice in the video that the car was going very slowly in front of the crowd. This was intentional because we've all watched too many YouTube videos of this sort of thing happening and wanted to make sure that nobody would get hurt should anything unexpected happen. Once the car was past the crowd the accelerator was pushed in a straight-line as I have done many times in the past when the rear snapped violently. The car was going ~30mph at that time. The car has been driven for 4700 miles and has been driven with DSC off many times including in the rain and never has the car snapped so violently just from accelerating. I chalk it up to several factors including cold temps (low 40s), cold tires and incorrect psi (more on that later) and of course driver error. More judicious use of the throttle should have been exercised. MDM mode was not used because MDM is too quick to intervene and cuts power prematurely (or maybe not).

Usually when the rear breaks loose, it does so progressively and steering correction will suffice. However, you can see in the video that the front tires are turned slightly to the right indicating opposite lock was put on the steering trying to prevent the car from doing a complete 180 however there wasn't enough real estate to counter how violently it snapped - though admittedty the gravity of the snap required immediate full oppo lock which was misread. I'm not sure why some are saying that no steering input was made because it was - one could argue it should have been sooner but again usually a little wiggle just takes small steering input and power through not a full-on immediate opposite lock as was needed in such a big snap - to me it actually seemed like it was happening in slow-mo although the vid makes it seem like it happened so fast. As the car started to correct it became apparent that there was no way out except over the curb which is where I put on the brakes and tried to straightline the curb as much as possible to avoid hitting the curb at an angle which would cause a lot of damage and potentiality flip/roll the car.8

I've driven many high hp rwd cars including vipers, porsches, corvettes, and formula cars and I've graduated from formula racing schools and have years of training in advanced car control and plenty of track time. Heck I remember day one of Formula school, half of the first day was spent on the skid pad learning how to keep a car from spinning if you lose traction. Maybe I need a refresher since it's been awhile and I've been driving AWD Audis for the past few years. Some of those other RWD cars I mentioned will snap fiercely and you have to be on extremely high alert, however my experience with the M4 has been that it tends to not snap so viciously in a straight line - but this time I was wrong. I would caution anyone thinking that it can't happen to them (count me as previously one of those) that anyone can make a mistake. I'm thankful that nobody was injured from such a mistake. Surprisingly, the car seems to be driving just fine with the only damage being the right plastic guard underneath the bumper which can be seen in the video. Surprising I know. 9

I mentioned earlier that I had incorrect PSI - let me explain. My PSI was low, so I inflated it a bit with a pump with an analog tire guage which of course is very imprecise compared to a digital gauge. I noticed that my right tire pressure was 1.5psi off of my left when viewing the PSI from the BMW onboard digital gauge (you can only do this while driving). However, as my car had been pulling to the right from day 1 of delivery (there's a big thread of many complaining about that on these forums). Miraculously, the car drifted to the right to a lesser extent with the right tire PSI being slightly higher than the left and so I was playing around with the idea of keeping it that way for a short time- however I knew that I needed to put the PSI equally across both tires but I just failed to do that before going to the meet. I have no idea if unequal PSI left to right contributed to the right rear spinning so differently than the left. 10

Anyways, I know I'll be ridiculed and called an idiot (and rightfully so) but I think many of you also know that I didn't do anything intentionally out of the ordinary or unsafe. I'm not sure I was even trying to show off as acceleration happened when the car was past the crowd and it's not like a powerslide or burnout or anything of that sort occurred. 11

I also think the M4 is a fine car and I have no complaints about the amount of power or torque or tire width or grip or anything. In fact, the whole reason I got the M4 is because it's not AWD and I like the rear moving around a bit. Mistakes happen and I've learned a lesson - and from now on will keep DSC on when driving around because there's too much at stake to make a mistake while driving - no matter how good or bad of a driver you are. Thanks for hearing me out. It certainly has been a humbling experience.12"

E55Freak

he thought he was in the "twistys"

HeissRod

1.5psi difference caused it? lol

Also, he had no reason to be traveling with DSC off if he wasn't planning on showing off.

He admitted fault to everything except showing off. It doesn't matter if you do it in front of the crowd or not. You were still showboating.

A-A-Ron

This guy is an idiot. He is not a part of the usual Blackhawk C&C and he is backtracking online with this statement because the event has been threatened to be cancelled because of this incident. I am not a regular but do attend from time to time and not many people knew who he was or where he came from. I guess thats a BMW owner for ya

kp89gt

Looks to me like he didn't steer into the turn at all! Let it keep going and ended up in the other lane.

Didn't look like any "snap" to me at all.

WANTED!!

Based on this video, he's not the only offender but just the one who ****ed up. Frankly, this particular meet is it's own worst enemy.

His post is a crock of $h1t. No driver with that many years of driving schools etc. and experience would just let the car and not counter. Especially on an open stretch of road like that. I'm glad it was a humbling experience, and maybe one that shows you shouldn't own a car with any sort of decent power. Thankfully, there were no oncoming cars you hit because of your stupidity.
You screwed up and can't drive, plain and simple.

hachiroku

lol at the lies....

he obviously dropped a few gears and hit boost and lost it instantly. horrible driver skills if i must say.

Thericker

More like NO driver skills whatsoever.. Scary to realize we share the roads w/idiots like this everyday..

layzie12g

How embarrassing. I would have kept driving until I found a pier and drove off the end of it.

veryswag

wait a second, i recognize that guy from somewhere

KMS11

Nothing beats these morons..

PeterUbers

I felt so angry for the people those dooshbags hit... Love the hit and run mustang...

ArmoE55

Can people keep posting links liike the Mustang one? Man, those idiots had me rolling. But I'd be one PISSED driver if some dumba$5 nailed me while I was sitting a light/traffic like that.

KMS11

No doubt I'd be mighty upset.

veryswag

'Murica!
land of the ****box cars not worth their weight in pennies

a few years back we were in my friends mustang GT on the hwy in the rain. were driving along at 60 and a slight dip in the road caused the whole back end to break loose, hit the cement divider, then whip back the other way to do three full 360's across the hwy. it was around midnight so traffic was light and we were lucky to not have gotten obliterated by a car coming down one of the 3 lanes we spun across

since then, i've lost even more respect for these death traps. i get a good kick out of watching these american car guys at meets make fools of themselves with there hot wheels toys. i make sure to watch from a distance for obvious reasons...

islandbeef

HeissRod

Holy ****! You think that's because the car is American?

Any RWD car can easily spin in the rain.

Let me guess.....he was really doing 80 or he was using cruise control or he wasn't just driving sedately along in a single lane.

veryswag

no, he was actually doing 60 and no cruise control.
it was an automatic ...RWD should not break loose cruising down the hwy at 60 mph, that is insane. **** ive done 100+ mph on my bike in the rain!
..i have seen many times also high end RWD exotic cars break loose on completely dry pavement, but this is in a stickshift & was always 100% always major driver error & in cars that made easily 2x as much power as his mustang. it was an 08 mustang gt btw

what really did it for me was 2 nights later, rain again, i see brand new mustang 5.0 being towed out of the trees off the side of the highway & no other cars were around. smh. ....trust me, i understand very well that driving any sort RWD performance car requires some level of skill on the part of the driver & knowing how to keep control, but at some point i draw the line. chargers, challengers, camaros, gto, mustangs, etc. - i wish they all had been left in the classic era, where they've earned their mark. imho
