The Continental ExtremeContact Sports are a great tire if you want something that will give you about great road feel, highway drive ability, and wear that won't cause you to look twice and the manufacture date code. I should note that I do not do track driving, just long distance drives and canyon carving. Its a great tire that holds its own to the MPSS without the cost. I am not an expert driver, so most things I have thrown at these tires have been shrugged off. Even at the limit, the tires break gradually and allowed me to keep the car under control.
I have had my current set of tires for just under 2 years now and I am going to need replacements soon (5k miles /year). Even though there is actually a decent amount of tread left, it looks like the rubber might be near the end of its number of heat cycles. I did not think I would get to this point with a summer tire that can do some rain driving as well, so I am def pleased with them.
Are there better tires out there? Of course, but for a tire that's going to be used for off track driving, its a fantastic choice if you don't want to drop the cash for some Michelins (especially if you know you aren't really going to max them out anyways).
