I have for sale a genuine exedy mx5 1.8 3 piece clutch kit. It's brand new never been used but has been fitted and I don't have the box.
I've decided to go for an uprated clutch to cover any future power upgrades.
Fits mk1/2/2.5 1.8 mx5's. Bought from here:

£85 posted mainland UK. I'll chuck in a copy of the receipt too for any warranty issues
