Video: Porsche GT3 becomes an axis of understeer

axis-of-understeer

Our friends at Axis of Oversteer drive fast cars, and they often drive them quite well. The team there participates in many forms of grassroots racing, while also running a Ferrari 458 in the Challenge series (with a rather lovely livery on it). It’s not always rosy out there while racing, however, as one of their friends recently found out.

Running at the Nürburgring, driver Andrea Sapino was campaigning his Porsche 911 GT3 Cup racer during a VLN event. Upon entering a corner in the area known as Flugplatz, the wheel studs on Sapinos left front decided to call it quits. Those are rather important as they keep the wheels and tires attached to the car.

The driver is fine. The car will be rebuilt. The video, however, is pretty terrifying when you see it from the drivers point of view.

    Apparently the driver is mute.

    'Cuz there's no way in hell I'd be sitting there with cars coming at me at race speeds and I'm not screaming.

    Even at much lower speeds this does not produce a good feeling in the middle of a race. At that higher speed…. wow.

    I'll tell you what, It wasn't fun losing all the lug nuts off the right rear wheel of a van, loaded to the gills with ceramics, and towing a trailer more fully loaded with ceramics. And that was at moderate highway speeds on a straight, flat road with no other traffic, at midnight. It would have been alright, except the wheel tore off all the studs in its departure. So we were stuck. This fellow must have had a really big thrill there for a minute or so.

      Similar – left front, no trailer or ceramics, though. Highway, 2am-ish. The only other traffic was the other 3 vehicles in our group. They were impressed with the spark show.

      We ground to a stop at the top of a weigh station off-ramp, I went down the ramp to find the station manned & left word that someone would be by soon to pick it up. A couple of other guys found the wheel on the other side of the Jersey barrier about 1/2 mile back. We loaded 6 people & their luggage into the other 3 vehicles and off we went.

      Firestone, after much protest, agreed to get someone to drive ~3 hours from Indy to northern KY to pick it up, trailer it home & fix the damage, since they'd mounted new tires all around the day we left.

      Lesson learned: always check lug nuts when someone else does the work…

        I always check the wheel lugs after bringing my car to the mechanic. When I got new tires on my car last month, all of the lugnuts were loose.

          After five cases of loose wheels/three of wheels coming off in our family, alone
          I now take my wheels off, take them in for new tyres, and then refit them myself.
          I tell myself that's why I have more than one vehicle so there is an upside.

    Amazing how the driver of the blue car (Aston, I think?) was able to avoid the wreck between the car and the wall on the grass. Especially on a tricky looking dual apex corner that's probably enough of a challenge without all the traffic and a wreck.

  5. ptschett says:

    You picked a fine time to leave me, loose wheel…

    Not such a 'Happy Racer' any more, huh?

  7. FЯeeMan says:

    It seemed like he may have had a front-left/right-rear tap with another 911 at about 0:50. If so, I wonder if that's what caused the damage that finally failed him.

    • Jeff_Glucker says:

      Apparently he re-used the same wheel studs from a prior season of racing.

      This is a no-no.

      • Eric Rood says:

        Wheel studs and/or hubs are one of the most-common failures (along with brakes and overheating) in LeMons races, even when teams have replaced them recently.

        With high-dollar, high-power cars tugging much harder on the (probably much higher-quality) wheel studs, I'm surprised there aren't more failures of this nature if they're not swapped out at every race. Still, that's a completely terrifying place for it to happen.

      • Nugget says:

        A 997 GT3 Cup does not have wheel studs. They are center lock wheels. It must have been hub failure (which is, admittedly, also a wear part that should be routinely replaced).
