Umm why do u call them tires if u from Syd
They dont look that bad, how many laps did he do? I seen worst from track days.
My OEM Bridgestone VR's lasted 50000km with 2 nails in them

not really a track person but if i did do track work reg I would go out and get track day semi-legal tyres.
You mentioned he is running a MY02, on MY05 tyres, did he notice a large difference between the original OEM's and these for everyday use and wet weather?
