Replaced a set of Yokohama S-Drives with these tires on a turbocharged Miata. My driving is mainly high-speed country roads. I also do some auto-X. I'm getting better handling/traction and a better ride with these tires. They also have a higher treadwear rating than the S-Drives, and I got excellent life out of the S-Drives. Good handling, smooth ride, treadlife and good price. Happy with this purchase.
