Ok my bad let me correct myself it was a reseller that said that and it wasn't that they will break them. its that they could break if used in the wrong manner since they are such a heavy duty clutch, i only had the stage 1, i don't know maybe i was just young a dumb... but don't get me wrong ACT is the best around... but now im just getting to old and don't like the heavy peddle. thats why i like the Exedy/fidanza clutch and flywheel kit.. Sorry everyone if i was acting like a ass i apolagize now..
