I have used Toyo Tires on race cars and without question they are hands down the best tires on the market for that purpose. I did a season of endurance racing - 40 hours total including the 25 hour at Thunderhill in my souped up Honda (go ahead and laugh, it lapped Thunderhill quicker than my SPF with a 427) on ONE set of tires. They are the greatest. One has to think that the street tires are killer too...
