Had the bolt which goes through the ERP bump steer setup break.
In a BIG way.
Going through turn 9 (at Pacific Raceways in WA State)
Approx 90 mph and at full throttle the right (relatively unloaded) bump steer bolt broke -- quite possibly due to overtorquing.
Mid corner the steering got lighter - and the car just went straight. Very little control. Just tried to keep it straight. Right through the gravel, like a shot. Bounding, bouncing, ripping and scratching at the underside of the car until the left side caught and spun me around in a 360. Heading towards the wall, both feet in.
Point of breakage was way up the track in the pic below. I ended up where I took the picture below.
I have never seen a car spin in this corner and NOT hit the wall.
Many have been a total with at least some injuries.
In the words of the track event chief:
"You need to go buy a lottery ticket tonight"

Probable cause? Over torque of the bump steer bolt.
A metallurgist who was driving at the track said that the bolt had been fractured for quite some time - and that the portion holding it together consisted of only the center 1/4 of the bolt.
She went home in a friends' trailer.
Got to drive his 440hp 930 - on Hooisers - home
Very lucky. Watch that bolt torque!
