shonen, with your tires i would get them before you go down if your gonna push pretty hard, depends on your driving style there too! also if they are pretty soft compound tires they will take a bit of a beating!
i would get new ones and do at least 500km on them before you head down!!
im still good for this day should be bringing at least 2 cars with me on the day too!
hey Tosh, you got a number on how many coming so far?
