So a little update:

I destroyed the clutch on Friday evening (solo hills run) FML......

It's Not holding anything above 3 psi anymore.....pretty sure it's thrown the friction material off one side of the clutch disk.... lol!



So using my contacts at work I've ordered one of these little puppies:



(image for reference only- my kit is by Clutch Industries)

The clutch plate is dual material, Organic on the diaphragm side - ceramic on the flywheel side. The idea behind the dual material is to enhance torque capacity (ceramic side) whilst protecting the driveline (cushioned between both friction faces) & having a progressive bite (organic side).

Anyone wanting to know more should look here:Friction Disks

Watch the video 3rd down on the left.

The kit is spec'd to handle 45% more torque than their full organic RPM kit.

The RRp on the 5 speed kit (p/n: Rpm1911N-OC) is $1400.

Fitting next week by Evo R, along with a refill of shockproof & new output seals.

And that <<<<Finally!!>>>> should be the end of my clutch woes!

^ Sweet! As you said, should have done it ages ago.
I hope it works as well in practice as it does on paper.

Are you able to get them trade for other people Rossco? Surely you wouldn't have paid retail!

Neg unfortunately, I called in a favor, I won't post what I paid for the kit - but let's just say all up including fitting will be around $1200.

Looks pretty awesome Rossco. Looking forward to hearing your thoughts / review on it once installed.

Clutch is in!

Initial thoughts?

No harder to drive than a full organic clutch
The initial 'bite' is very progressive.
There is no clutch shudder at all
There's no overrun noise, actually there's no noise from it at all.

One issue I did have initially was the clutch friction point being too low (like 15mm off the floor), the old clutch was like this also, I knew it wasn't air in the system now (as I thought it was) - it was bled today......HMM how to fix?

The fix was a simple adjustment of the clutch pedal push rod:



You can see the clutch pedal upper stop in this picture as well as the clutch adjustment rod. This component goes through a boot in the firewall and connects to the clutch master cylinder. The rod can be turned left or right to alter the point of clutch engagement above the floor, longer = higher friction point - Shorter = lower friction point.

The friction point is now 1/3 the way up from the floor...Woohoo!

But why was this adjustment required?..........Lightened flywheel!

The lightened flywheel is thinner than the stock one - effectively moving the clutch fork pivot point & the pressure plate further apart, which in turn requires slightly more 'stroke' at the master cylinder to return the pedal to a 'normal' feel.
