Hello all,
I was at the event and know the guy who owns the car. (No it wasn't me)
I was in the paddock area next to him changing wheels at the same time as him. I watched him torque all of them. I even borrowed his torque wrench to tighten mine (I always forget something after I get on the road).

He went to a wheel/tire business and asked for spline drive lug nuts for his particular make/model/year car for the Enkeis, and that's what they gave him. He did not purchase the tires or wheels from them, just the lug nuts.

The lug nuts where sheared off the studs. Several members lifted a corner of the car to slide a jack underneath it. With a few more jacks, blocks of wood, etc, they were able to mount the stock wheels and stock lugs nuts (at least 3 per wheel) back on, torque them and drive the car off course. The design of the car, possilbly for aerodynamics, tucks all mechanicals on the underside a little higher than the body line, or lowest part of the brake rotors. Not even the exhaust was really scratched.

I'm not a mechanic, but the mechanics theories there was that the lug nuts where the incorrect size, but they were just small enough to grip the outer edge of the threads (as I mentioned, they torqued to 75-80 ft/lbs without complaint).

Hopefully, the only damage is to the body and brakes.

dayum that is freakin crazy

when i did the extended studs on my hatch I made sure to buy the correct lug nuts for them. but buyer be aware that many of the companies do not have the spec information you need to make sure you are getting the correct ones. do the research as much as you can.
if you can only race me in a straight line then whats the point ...91 SMF SCCA

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
