I'd been using this Achilles atr sport for the last 1 month and for a cheap tyre it's good. Grip at 200kph just like toyo, but you can smell the rubber after such a drive.But all tyres can go to 200kph, but it is the stopping that matters......
Braking at 200? you gotta ask those SIC track junkies dude. Quite sure some of them on Achilles.
