four wheels came off?

Now that _would_ be exciting. I've seen a full-sized Jeep Wagoneer lose both rear wheels at one time when the driver went way too fast over a whoop-de-do on the Alaska highway up in the Yukon Territory with far too much weight in the rear. Sheared off the studs completely. I gave the uninjured driver a ride to the next real town (Whitehorse IIRC) in my VW where he was told that getting his vehicle hauled in, obtaining replacement parts, and performing the repairs would take a week and cost a huge amount of money. I left him there and drove on, a bit chastened and moving far more sedately.

Still, *20* at one time? Is it a record?

I think even for an RX-7, that's got to be a record ;-) Sorry Felix!

LOL... film @ 11.. I can only hope it makes youtube

That is kind of cool. The next time someone says, "The wheels are falling off," this driver can pull rank from actually having done it.

Did it oversteer or understeer?

Nobody was taping it. Of course, the owner was not too happy; extensive plate damage to the car from wheels sliding past.

Don't know. I was at a worker position way out, and my eyes were not good enough to see it. I only knew the wheels had come off when the guy next to me told me so.

But I would assume it had severe understeer. Or else why would the wheels come off at both sides? The way I would estimate the dynamics is:

1) Inside wheels pulled off. (Should have bought a VW Golf: rear wheel would have been saved by being in the air.) 2) Friction of iron-asphalt being less than rubber-asphalt, a moment results around the center of gravity that causes the wheel-less side to advance beyond the wheel-bearing side, producing a rotation of the car attitude compared to direction of motion. (I do not, at this time, know whether the driver was trying to steer into the turn, but the way I see it, no driver steering input was likely to reduce the iron-side advantage over the rubber-side resistance. The driver may even have tried to apply the brakes.) 3) The wheels are now "behind the motion" (or to be precise, the velocity component normal to the plane of the remaining wheels is now directed towards the car instead of away from it,) causing the remaining wheels to be pulled off too. 4) Performance is reduced to the stage of "this RX-7 is going nowhere fast."
