Saturday I was competing at the autumn speed final at Shelsley Walsh. There were several MX5 taking part and one of them a 1.6 Supercharged lost it coming out of top esses and hit the bank and overturned finishing on its roof. Luckily his father had fitted a rollbar which saved him, even so his head was cranked over but escaped unscathed. The windscreen just folded and without the rollbar he would not a be here.
I do not have one fitted to any of my roadgoing MX5s, but will be seriously considering it now.
