I have seen a borg beck elise s1 clutch fail in the same way , ie. rivet failure

 

They have very little torque, but what I was trying to say was I don't believe prolonged torque force is the problem , until the friction plate itself is the part unable to rotate. The inner springs will dampen some abnormal shocks , but if they have reached their limit, then the rivets are the next thing to go.

 

If you look closely at the first picture on the thread you can see that one or 2 of the failures is close to the rivet, but mostly the metal has sheared through higher up than that. must be some type of shock load ie high resistance and high torque at the same time ?

 

What i cant quite get my head around is that the shaft was put back in in France and driven some way before it popped back out again and made the journey to Neil's house on a loader, hence the clutch was operational then.  or has it been sending shock loads through the drivetrain and popping the shaft out due to those.

 

Chicken and egg situation.

After a bit of digging a cheaper performance clutch same as Neil already has (CS competition)

how about 76 variant , 76-4993 cerametallic paddle drive sprung hub

 

is the cover plate a lighter 60-4990 or a heavier 60-4996 ?

For the chaps that wanted to see a close up, Here you go.

You can see by the rivet depth that it's about done anyway.

Sorry lost me on the clutch variants Sent from my SM-G903F using Tapatalk

Also the clutch has seen some use all the damping springs are loose and many have started the journey for freedom. Sent from my SM-G903F using Tapatalk

That is poor the clutch  wasn't that old as i had a fast road clutch from courtenay and that exploded and took the flywheel out as wel,l  then fitted the competition clutch and new ttv flywheel .

I dont do much 1/4 mile driving more recently with the new Engine and  paddle clutch .

looks very strange the way it has broke .

Maxr had a competition clutch, that lasted one lap

No one can say that friction material wasn't up for the job.

Think the turbo clutch is just under £1k

Out of interest how do you find the 5 paddle on the road? Is it manageable or is it awful? Sent from my iPhone using Tapatalk

[CHILL Gone DUTCH]

actually mine is a 4 paddle 

ive driven lee car with a paddle clutch and lukes and there both more drivable than mine 

 

but mine is not that bad 

[CHILL Gone DUTCH]

i would fit a paddle ceramic clutch and forget about it 

 

should last even when you decide to upgrade the power 

[CHILL Gone DUTCH]

what have you decided to go for ?

I’m looking at one on eBay. Just don’t want to ruin it for road driving but don’t want to be in this situation again in 12 months. Lee only fitted the current clutch in Nov 2016! God knows how it’s deteriorated so quickly. I’ve barely driven it and Lee didn’t do many miles / track days with it in he few months he had it. So I don’t really want to put same in again.
