Uprated clutch disc Vs Std disc

[Nova Modder]

i know a std clutch dis lasts about 90-100k miles... do the uprated ones have a longer life span in a std car or are they really only for ppl with obscene HP commin outta their engine ?

[mark_GSi]

i put 1 in my GSI when i rebuilt it.

group N (uprated) clutches normal last longer and can handle more power.

i would uprate it m8ty, worth it, ive never mad ne touble with mine :wink:

how can you tell between a GM clutch and an aftermarket one.....?

[mikeoxford]

what i mean is when i take the clutch off a race engine i bought a couple of months back, how will i know wether to put the cluctch on mine or not bother?

[Nova Modder]

thats what im wondering about... the guy at the clutch center sait buyin on aint worth it..

but there must be a benifit somewhere... like longer life or somthing

DOES ANYONE KNOW?!?!

Performance clutches are quicker engaging and disengaging - hence quicker gear changes as well as handling the power better.

They are made from stronger materials - so they can handle heat better etc etc.

Normally an aftermarket performance clutch would have possibly more friction plates or have a name on like `Sachs' or `AP' rather than GM

how can i tell if a clutch is worn looking at it?

dont want to swap a clutch over before fitting, only to find it starts to slip or its no good after a week or so..........

[Nova Modder]

well....
its like a tyre..

Imagine looking at a brake pad - when its dead its friction surface is visibly worn down, same with clutch.

Normally when extremely worn the rivet heads get worn down also on the clutch plate.

If replacing a clutch its often a good idea to replace the release bearing as well.

if you have the engine out, then stick a clutch in it. unless you are racing it, use a std road one, maybe check out the GM diesel clutch options, as diesels have much more torque to transmit & the clutches are stronger.

I don't believe that a performance clutch will last anything like as long as a std one.
to get more friction, you must get more heat, and thus more wear, same as performance brakes.
