The HD and the XT are the pressure plates and the MM and SS are the discs. That's the difference. The XTMM that you are showing at 277 ft. lbs. goes up to 307 ft. lbs. when using the SS disc instead (becoming the XTSS). That's why.

I didn't realize that they didn't make the HDSS for the 1.6 flywheel (mainly because I'm a 1.8 guy). The ACT designation for the 1.6 cars is ZM1 and for 1.8 cars ZM2. If you look at the linked page, the ZM1-HDMM uses a 45% stronger PP and the ZM1-XTMM uses a 100% stronger PP, both with the same disc. Either would work with your existing flywheel, but you need to determine your torque-holding needs (ft. lbs.) and your desire to have a light versus heavy clutch feel.

If you would like to step up to the 1.8 flywheel, there are probably several on the forum that have gone to a lightweight flywheel and have their old ones gathering dust. The 1.8 uses a slightly larger diameter flywheel surface area to handle a little bit larger disc. The increase in clutch surface area adds some torque-holding ability. Those will be listed in the linked page as ZM2- part numbers, like the ZM2-HDSS that I had recommended.

The real questions are going to be how much torque do you make and how much torque do you intend to make in the near future? The 200ft. lbs. ZM1-HDMM may be enough for a mild setup.

Or you might be budget limited to that level. Besides, the clutch might act as an electrical fuse does and protect the drivetrain by giving slightly under a shock load if you don't go too stout.

Or you could overpower it and smoke it. Know your needs and limitations.

Good luck.

My ACT HD "Kit" was just a pressure plate with a stock exedy clutch. I'd bet you could recycle your existing clutch and just buy an ACT HD pressure plate if you wanna go that route.

ACT HD with a street disc. Order, install, enjoy. Don't dick around with eBay clutches or trying to salvage some part of what you have in there right now; order new, do the job once, and be done with it.

Carolina Clutch had the best deal when I ordered mine. I've been abusing my ACT HD for more than 30,000 miles now and it's never given me any trouble.

Get a real clutch with a real disk, not a puck. Then you've got something. I run the Chuck Noris stage ACT PP with a regular disk and it holds more torque than you could shake a stick at.
