I have been following a discussion on another forum about the new Hoosier Speedster tyres (tires) which are becoming popular in Triumph and Porsche 356 circles.
A claim was made that Dick Stockton, a TR4 racer got readings of 1.3 to 1.4g in the corners on "data aquisition" equipment.Most vintage racers don't have any way of getting this kind of data, and I assume it was a G Tech meter or similar, and possibly 10% optimistic.
Even allowing for that, this still sounds like a fantastic figure for a car on treaded vintage-legal tyres with 7 or 8 heat cycles in them.
I realise a skidpad with a 200 ft diameter will not give as high figures as a corner with a 500-600 ft radius, like some of those at Watkins Glen, but isn't this getting close to the figures Can-Am cars got back in the 60's with huge slicks?
Anyone have any data, or opinions?
Simon, (tormented in Toronto.)It would have been better if I could say Puzzled in Pittsburgh!
