Hi guys, Im just wondering do i have to worry about the tiny hairline cracks (no longer than 5mm) on my front discs, they r standard turbo brakes, I noticed them after 4 average (not full on) laps of a track, they may or may not have been there b4?

Im just concerened bcos several cars involved with uprated discs (and much harder use) cracked theirs...

Cheers Fergal

Fergal,
it happens to alot of cars, 'if' the car is still in warranty, the dealer 'should' replace them foc, they might even upgrade to the prodrive discs if you've got a good dealer. It would seem that you need only worry when the cracks get big.
