If you don't drive C63s as a daily, I would suggest the Nitto Nt05R. They are amazing. My little 3 liter makes almost 650 hp and over 500 tq and they don't spin much even with a manual. The auto would be even nicer to them.Also Hankooks grippin like a mfer! Fr try em out they're on the C63s and those things are tire killers. Ventus Evos
