If you were going for a clutch setup on the st170 engine with rx8 box, what setup would you choose?

The Rx8 box shouldn’t make much odds. I was not “telling you of for” using the St170 flywheel. Just giving reasons why nobody else uses it.
If your sticking with the dual mass fly as I’ve said it’s a unique combo and your going have to keep playing until you have worked something out.
If your thinking of changing the flywheel to a solid unit.
Standard 1.8 220mm flywheel and good quality clutch should be ok for a standard carb / injection st.
Standard 2.0 240mm is heavier but will hold more torque.
Turbo, standard 2.0 with Focus Rs clutch.
All of these are tried and tested and I’ve never heard of a standard manufactures flywheel grenadine.
I won’t bother suggesting light weight flywheels as you have already made your feelings clear.

I am getting a full 10mm travel with the thrust bearing going against the pressure plate/clutch cover and yet the clutch plate is not releasing. Any
ideas why?

Thanks Wasa. I was thinking of the Standard 2.0 240mm with Focus Rs clutch. Is the RS clutch 23 spline? Thats why i used the MGB clutch plate.
What is the depth of the 2.0 240mm flywheel please? With the dual mass fitted and all the "freeplay" removed so the the thrust bearing
actually is about 1mm off the cover plate fingers it is pushing in 10mm and its not enough. I fitted the larger master cylinder with an extra 25% push
than the MG unit and it will not go to the floor with the RX8 slave cylinder. If the 2.0 240mm is thinner then it has no chance of
clearing............ or am i wrong.

Rs clutch is made by Ap and is the same size as the standard 2.0 it uses the same flywheel and runs in a version of the mtx75 although not identical
to the focus / Mondeo casting..
Flywheels drilled for a pinto clutch, the clutch is deeper so no need for the thicker thrust bearing in a T9. Again your adding more variables into
the mix.
Have you had a chat with Jonathan who makes some of the Rx8 adapters available. He nearly always recommends a standard flywheel and clutch. He runs a
Zetec in his Escort with the Rx8 box and gives it death.
Just ask him what he is using..
I think it will be a standard Zetec flywheel and clutch.
You will only need the Rs Ap clutch if you have a very serious St or forced induction.

The Focus Rs flywheel is the same as any 2.0 Zetec by buying an Rs one you are paying the Rs tax for a flywheel that will have had a harder life and
got much hotter.
The clutch you have linked to is not a Focus Rs clutch. If you find a genuine Ap Rs clutch your eyes will water lol

I may be able to have a measure at the week end if I get a chance to fit my new flywheel.

Thanks for that Wasa. Re: a chat with Jonathan, is he just on as Jonathan?
A chat would be good. I bought my adapter from a John, I think from Wales.
I noticed the pinto clutch with flywheel and thought a good price. Are they reasonably strong? Im not racing it though the odd burnout would not go
amiss.

The pinto fly wheel doesn't fit a zetec / st.
You can have a zetec fly wheel re drilled to take a pinto clutch but your then mixing things up again. The advantage of this in a zetec / t9 is no
messing around with thicker thrust bearings and you get more clutch travel more clutch travel.
John has a face book page called Rx8 adapter plates or something similar.

I removed the complete flywheel today. The Dual mass flywheel is 54mm deep. Quite a lump. Do you happen to have a zetec 2.0/1.8 that I could buy from
you? Im in Southampton so postage needs to be added.

I purchased the cougar flywheel thanks. Incidentally the mgb b&beck heavy duty clutch and cover is a bolt on job with the st170 flywheel. no mods
needed. Its approx 57mm deep. am i right that thats the same as a pinto clutch cover? The dual mass is 54mm deep.

Nope,
The pinto cover plate is deeper than a Zetec hence why you would need the thicker cct133 thrust bearing in a t9 to make up the difference.
It’s not a bolt on fit to a Zetec 220mm flywheel, it needs redrilling. The clutch plate is also slightly smaller at 215mm.
The debate about a rwd clutch having more travel has gone on for years. Both ways work.
If you now have a 240mm fly I would advise making life easy for your self and use a standard Mondeo / focus 240mm clutch plate and cover. The starter
motor is the same. It’s then just a case of adjusting either the slave pushrod length or the pivot point or a little of both.

Thanks for that. I have made a plate about 8cm long with a long slot to take the bolts for the slave and welded it to the slave cylinder where the two
attachment “tabs” were. It will give me about 4cm adjustment backwards and forwards. That will help with the thrust bearing to clutch cover alignment.
I thought that the plate may have been in back to front, but not so.
Will I need to re-drill the cougar flywheel? Thanks for the tip on the clutch from a mondeo/focus.

My opinion, you don’t need a sports clutch unless you have forced induction ie turbo or supercharger.
A good quality Oem clutch is more than adequate. Ideally I would look for an Oem motorcraft clutch of a crate engine. There was loads of them kicking
about as most wanted the 1.8.
After that, any of the recognisable brands. Sach, Luk, Even the old Qh.
It needs to handle torque, the 2.0 was designed to pull a ton and a half car, five adults and a caravan up and down the hills for at least 100k
miles.
Check the specs before spending your cash.
