Suspension Problems of Porsche 911 Gt3

Front Suspension Hub problem #1

Right rear centerlock hub failed/sheared off resulting in high speed exit from road surface and 800' slide. Wheel and tire left vehicle and traveled approximately 1500' crossing active road. Centerlock nut was found about 700' from vehicle. Issue seems to be failure of the centerlock hub can result in loss of wheel and vehicle crash. Buttonwillow raceway park, CA upon exiting buttonwillow turn 12 (cw direction), loud pop heard from right rear of car (witness describe very loud pop/bang "like hand grenade going off"), vehicle immediately rotated counter clockwise and exited road surface, sliding sideways (right side in direction of slide), right side down, left side up (both occupants noted they felt the vehicle was going to roll), parallel to the road surface. After sliding possibly 600 feet, car hit intersecting road (about 6 inch rise in surface) becoming airborne for possibly 20 feet passing over the road and pivoting clockwise. Upon landing, car slid parallel with original road surface, aligned with road coming to rest after about 800 feet after the hub failed. Car did not roll, the slide sideways and likely the impact with the cross road did significant damage to the car. Details on vehicle: - wheel was installed 2 days prior to incident after changing to new dot tires. Porsche centerlock mounting and torquing procedure were followed, torquing to 444 ft lb. - torque wrench setting was verified after incident and found to be set properly to 444 ft lb. - data shows vehicle was traveling about 100 mph, with throttle on and loaded with 1. 1 - 1. 2 lateral GS (turning left, loaded on right side), brake and steering information is not available. When hub failed.
