Had a rather nasty failure on the car today. The one of the quick camber adjusters on the front suspension decided to catastrophically fail and allow the top wishbone to detach from the hub.
My friend chris was driving at the time luckily he noticed that it had failed and stopped before the front wheel parted company with the car.
i would seriously advise you to think about changing them for stronger items if they are on your car or revert back to the book wishbone design with the fixed threaded tube
this is the adjuster in question
and this is the failed one.
yes your not seeing things the bolt head as completely come off
