I autocross a 94 GT with worn out KDW's on it now and am looking to purchase new tires in the 275/40 17 size. The two tires that caught my eye are the NT05's and the Kumho XS'. The mustang's not my DD so wet traction is not an issue at all. I would use these tires on the street as well, but the car only sees the street 2-3x per week. My question is, what tire will give me the most satisfing autox experiance? That is, quick to heat up, dry cornering grip, and predictibilty at the limit. Also, it's likley that these tires would see the drag strip once or twice a year, so any input on straight line performance would help. Thanks!
