Didn't have my SLR with me on the track so you get a crappy iphone pic.
Things were going well up until I got on the gas after turn 11 at Laguna Seca. The back end kicked up as the hub sheered and the tire exited out the rear. Came back down on the rotor which snapped in half. As the car came to a rest I saw the wheel rolling by off into the sand trap. I'll have to get my friend's video who was right behind me. He didn't get it as the hub snapped, but you can see the wheel still rolling off.
Overall not too much damage, but without an extra rear hub and some welding gear + 2.5" exhaust pipe I had to take the car home. Getting it on the trailer was fun.

Factory hub - I think. I'll take a closer look tomorrow. The previous owner's notes said the bearings were replaced and studs were pressed in, but nothing about new hubs. I just e-mailed v8r to see if I can get a set of hubs from them.
No warning before it let go. Just happened as soon as I got on the gas.

What's left of the hub after I pressed it out of the knuckle and pressed out the lugs. I guess it's not a stock hub. It's 26 spline, however the diameter is bigger. Only thing I could match it with was an escort zx2, but not sure if the spline size is right.

The car is still on the trailer so I haven't had a chance to check the other hub. I was hoping to replace the broken one and drive the car off, but I haven't found a replacement that works. If no one wants to inspect the hub I might ghetto mig weld it back together so I can bolt on a wheel and push or drive it off.
2 and 11 exit are especially bad on the right side at Laguna as I'm in third gear (or second if I get stuck behind someone) and applying lots of throttle on exit. The back end always kicks out on those turns. Most of the right hand stuff is high speed except for the bottom of the corkscrew but there isn't isn't a lot of room before 9.
