Steve, thanks for posting that link, really enjoyed reading it..
The one part of the McLaren F1 history I'm most proud of is it was the 1st time a car manufacturer won on the 1st attempt and the last race car built from a road car to win the Le Mans 24hrs
I designed this roll cage for the 1997 long-tail GTR
All designed before 3D CAD so we used welding rods to mock up the tube angles
I went extreme on the lightweighting, one of the less loaded tubes we had centreless ground down to a thickness of 0.9mm
My 1st and last ever roll cage, the car won GT1 class and came 2nd overall at the 1997 Le Mans 24hrs
