Had to pull off the bell housing tonight after over extending the piston. This is on a Spec mini-twin. I've read some conflicting stories on if the clutch stop is needed. On an 86 Turbo, it definitely is.

I didn't need it at first as the firewall brace I installed 'lowered' the clutch pedal. I finally got around to adjusting it back to the correct position tonight. Set back to stock length of 147mm, giving the 3mm or so play at the pedal, this gives enough through to the slave cylinder to pop out the ring.

The buna o-ring inside got chewed up in the process and I found aluminum burs on the inside of the ring as it was forced crookedly.

Will fab a quick pedal stop out of aluminum this week and waiting for some new o-rings to arrive. Size 328, and I think 50A durometer for anyone interested.

what it like driving it around with this clutch?

Noisy when the pedal is depressed - the twin plates rattle, but oh so much grip when engaged!

You can't really slip the clutch easily, it wants to grab, I don't recommend it for a daily drive. I have this on my 88TurboS

I do have a pedal stop on the firewall panel, it's a block of aluminum.

Interesting. Im looking to go this way with my 924. Custom flywheel, what not. Just for a lighter rotating mass.

Does it make any significant noise/NVH with the clutch engaged?

Can anyone comment on the pedal stop for normal single-disc SPEC push type, versus the mini twin? Same issue? The mini twin seems like overkill for 99% of cars.

Did this fill your bell housing with fluid? I have the SPEC single clutch that I am just installing. Still fabbing up the stop. I wasn't too enthusiastic about a little rubber O-ring being the only thing stopping a total dam burst. I was hoping it would be a sealed diaphragm? I was also curious what would prevent the 2 machined pieces from going off kilter like yours did... so do you have to re-machine them to clean up the aluminum burs?

I'd love to see a picture of how you fabbed your pedal stop. This is another very vague piece of the information in the package.

Thx,

Jase.

carriage bolt and nut attached to the back of the pedal would be simple enough and "adjustable"

This is my pedal stop, well it was until I had it removed and have since gone to a Tilton pedal box. It was made up by the guys at Fitzgerald Racing in Melbourne, Australia
