It may be true that no one with factory pads have pistons that are falling apart, but the issue is, if you want to track your car, what do you do? As Takahashi said, OE pads are only good for 3 laps (at my local track anyway but of course varies according to how much braking is required on the different tracks). Anyone who is buying this car to use for weekend tracking better think twice about it. But you can always go the route I did.
