The new Dunlop Direzza Sport Z1 tyre has won both the Econo Car and SUV Classes at the 2010 One Lap of America.

This event encorporates nearly twenty-four hours a day driving with competition taking place as time trials on race tracks throughout the country.   The event, as it always has been, is foremost one of endurance and vehicle preparation.  No support crews are allowed.  The tyres that are used on the street are the same ones that are raced on (one set per team).

This event does not allow 'R-Spec' or race tyres, so the DUNLOP Direzza Sport Z1 is the obvious choice.

The DUNLOP Direzza Sport Z1 has all the good manners of a high performance street tyre; low noise, good tread life, good wet performance, but its very high dry grip makes it particularly suitable for track use where specific race tyres are not permitted.
