I'll just go measure that piece of string.
With my considerable 18 months of experience I have come up with the following - medium rear, soft front
Up until last meeting I ran medium/medium. This was based on the exact science of what was available at the time. In the pre modern class I have seen hard/medium, hard/soft, soft/soft, medium/soft...never hard/hard though
The fast guys (Muzz Clark fast) normally run soft/soft. But they also tend to change tyres a lot. My last set of medium/medium I did 3 track days and 2 x 2 day race meetings. They still had lost of meat left on them but they were definitely not as grippy. (Too many cycles maybe?)
Ill now be sticking with medium/soft but will have to see how it goes at the end of the year when the track temp will be considerably higher than the 20 something degrees we had the other weekend.
Also I am now running Pirellis. I ran Dunlop for the first year and though they were OK and they were good value for money. Now I have gone to pirellis there will be no going back.
Probabaly doesn't help you a bit!
