have heard reports of cracking if used harshly often. iv had mine on front and rear for 18 months with 'touches wood' no problems

tbh though the best way to improve the gtir brakes is to uprate the calipers and fit braided hoses

I had these and EBC Red pads, split the discs within about 5000 miles :lol:

Had these on the car for a couple of years now and have had no trouble with them at all. Its almost time to change them, and unless I can find a decent price for some 4 pots, they'll be going on again

Mine have been on for roughly a year and are warped :shock:

in my experience grooved discs are fine, drilled ones crack and warp to shite.

they are excellent if used only for occassional fast road use or changed every few thous miles if used hard , if you want a good fast road disc thats not as susceptable to cracking try Brembo dimple drilled disc , quite cheap too email me for more info on them if you like.
