Description of what happened off you tube! Seems he removed the rear wing!
A small video of my car spining at the MLR 30-130 day at RAF Marham 03/11/07 - previous run of 182mph went fine, second run i removed the rear spoiler as it was bending alot at high speed; i hoped it would give me another 10mph, instead it gave me zero down force and zero stability once i came off the gas! Took a deep breath and held on until the ride finished!

Some stats from the V-Box data logging:

I lifted at 183mph and it only took 5mph for it to become unstable and went into a spin at 168 mph.

Maximum spin angle was 142.55 degrees at 114mph before starting to spin back the other way.

The spin lasted over over 330metres
