Nawwp big stretch of carpet towards the jump!
I had ago on Cris' car n it was fine, its his thumbs
But Dan it could well be if your running a smaller piston on the rear than front as Cris' back end was bucking up more than mine because of this. You may not of noticed the back end bucking up before because usually at Caldicot its a flat take off to the jump. The jump i'm assuming you had the back end kicking up that much more on was curved which does change the angle of the car quite alot. Pistons pistons pistons
