hi, I have replaced my clutch just because the throw out bearing was gone crazy making this noise while clutch is engaged so got myself whole clutch kit nd replaced whole lot, but when replacing found that clutch was at is end as well... I believe clutch can last you forever if driven soft, if u give abuse to your car it wont last longer than "short"
if your car doesnt slip on power while high revs, or makes no other noise while engaging clutch, I think there is no need for clutch replacement
