Exedy Racing Stage 1 Organic Clutch Kit 1990 1993 Mazda Miata 1 6L I4 DOHC B6 ZE | eBay
If it holds till rod breaking territory then slips and still drives mostly stock, I think I might like that thing. Seems a cheap choice with my stock FW...

Not sure if it was a 1.8L or 1.6L clutch but I always recommend putting in a 1.8L sized clutch anyway--it will always hold more TQ all other things being equal.
It's $310 from the same seller. The FM STG1 is $350. and the ACT ZM2-HDSS is $460.
Dont see the 949 on their website anymore.

When you go from a 200mm ACT HD to a 215mm the TQ load goes from 195 to 245. That's about 20% better with the same level PP and clutch disc.
here's directly from Exedy:
a 20% increase in TQ as well.
I just wouldn't use a 1.6L sized clutch for boost unless you get a super heavy PP with higher clamping loads. If you look at the difference in the diaphragm springs, it's apparent why:
teeny tiny:
vs.
large and in charge:

The new 1.8 flywheel is bolt on direct on 1.6 models?
Any problem with the starter or gearbox case?
