I ran the 6303 radials for years, after a 9 year layoff I'm on the 4457's, and can't seem to get a handle on them at all.
I took off 10 year old 6303's that were xeroxing time slips to the 60' @ 1.36-1.37, haven't had anything better than a 1.42 on the new tires, and have had to lower the 2-step RPM's by 600-1000 to have a chance of racing the car.
I had always done a "dragster" burnout with the other tires, except on real cold tracks.
They feel from the seat like the sidewalls are stiffer, maybe my shocks can't control these tires?
Any ideas? I had at least 10 sets of the 6303 tires on my car and loved every pass with them, getting 125+ runs from them bracket racing.
