Well update perhaps required, Cadwell park was going absolutely brilliantly, car was chipping on and I was settling into another day in paradise as of all the tracks in the UK, Cadwell is the one.
Then, coming out the gooseneck at about 11:30 ish, so third session, drop pin on my roll kit sheared and the car went fully Charlie Chaplin, ripped a bit of bumper off and skidded to a halt in the grass bank very gently.
Overall no harm done and the kit itself has been on for many years and many trackdays.
So, next step was removed and shift to the bridgecraft kit that's not bolt on, more intrusive but frankly built like a brick s**t house.
Onwards!
