Feddys 595SS = 9/10??? You gotta be kidding... I've used them before and they are nothing like what you said, brought it to skid pan, even worse, under heavy braking would lock up in DRY! After warming up, have next to no grip
Kumho KU31 215/40, 235/40
Dry: 7 / 10
Wet: 6 / 10
Value: 8 / 10
Not the best street tyres out there but they provide decent grip when they are new, my car probably have about 180rwkw, however once they wear down to less than 50%, dry and wet grip goes out the window and loses traction very easily
Will try Dunlop Z1 star spec next
