A year later on this post...... I'm at the B level and creeping into the lower (very lower) end of the A's. I'm moving from Pirelli SuperCorsa's to the KR448/449 8477 compound. I'm doing so because I liked the stiffer feel of past GPA's - tried the Pirelli's and feel just too much flexing (for me) under hard braking especially. Still a decent tire, just not for my style.
My questions are;
1) What hot tire temperature is best for the KR44x's (right off the track). Rule of thumb for most good street tires was keeping them about 140 +/- 5F. Same for the racing slick's?
2) Only monitoring tire pressure doesn't seem like the best overall way to manage tires - just sets a known starting point and for making temperature adjustments. Would you agree or am I overthinking this?
