Bruce ... speak about timing on the Avon subject . Just got an answer from the Technical Manager of Avon Tyres Motorsport/UK about using the CR6ZZ tires on the track ( I do VIR ) . Common thread for both of you is that radial tires want/need a lot more negative camber than most people are running , or are comfortable with . For example , the Hoosier R6`s a friend ran in SVRA , needed a minimum of 2 1/2 to 3 degrees negative and higher pressure than most others run . Realizing that there is no silver bullet and not all cars and drivers like the same thing , Avon suggested ( as you did ) that , a minimum of 2 degrees negative camber . They were comfortable with tire pressures of 32 to 34 psi hot in front and 30 to 32 psi hot in the rear , depending on the balance of the car . Monitoring tire temps will then be your guide . The range I was given was to shoot for was a delta of 10 to 15 degrees C with the inside warmer .
I also run 1/16" toe in per side on the front and 3/32" toe in per side for the rear for track and street .
I spend more time on winding roads and the track than Interstates and if I get 4000 miles to a set of tires , I`m happy .
