I think I can safely say that the AD08's are now scrubbed in. After a long blast down country roads I can honestly say that these tyres are awesome! The level of dry grip is huge, I can actually feel the Quaife diff working on corners now where before the Falken tyres would be scrabbling for grip. Wet grip is also very impressive for a tyre of this type. The sidewalls are stiff with no hint of rolling over on hard corners, but they are not crashy over bumps and they are not really noisy at all, you can hear some road noise but to me it is lower than the Falkens.
The Yokohama Advan Neova AD08 is an awesome tyre, really gives you confidence to attack corners that I would have backed off on before.
Overall I love these tyres and rate them very, very highly. If you're considering these for fast road/trackday get them, they are awesome!
