yeah Raul knows about the tyre sitch (old stock, extra soft compound). but they aint too bad value. I think he paid about $150 each, and providing you only are doing 4 or 5 laps at a time they will give stellar times as they are bullshit soft so would be grippy as hell. having said that, the 17inch ones the guy is selling are not such good value as at $240 each they are getting close the RE55 money.
