Numerous factors figure in, including corner weight.
Also a factor is what you set them at cold and what they end up at hot.
In my Spitfire, I set them 21F/24R for autocross, 18F/21R for racing. They
end up hot in the 25-27 range.
Used to be long, long ago my autox setup was just the reverse -- 24/21. Then
I lost 100 lbs on the front end by taking the stock steel bonnet off and
replacing it with a lightweight fiberglass one. Completely changed the
handling of the car.
