I ride a CBR600F4, and I'm used to DOT race tires for Peublo and formerly SCR but I get a funny feeling I can't get them hot enough at IMI. Overkill perhaps? Especially the soft compounds. I'm considering an ultra high performance street tire like Pilot Powers but only if it would actually be better. Is it possible that the nature of IMI is better suited to street tires? or race compounds all the way? The fastest I've gone at IMI is just quick enough to knee drag in most of the corners and that's if I'm feeling pretty good and the track is in good shape, otherwise I'm just out sporting around.
