ACT heavy duty for 1.6
While shopping for the clutch i want on ebaymotors, noticed something odd.
the clutch kit I'm trying to buy is the ACT ZM2-HDSS, or heavy duty pp with the performance street disc.
Many of the vendors were listing that the heavy duty pressure plate and performance street disc would only work with a 94+ flywheel.
the par numbers match the ACT site so I'm confused. Some vendors don't mention anything about running the 1.8 flywheels.
here's some links

plus seems the price is going to be roughly $390, anyone know of cheaper?

so they dont make a zm1-hd"SS" only MM, i was hopping to run the performance street disc.
i have both my stock 1.6 flywheel and a 1.8 of my friends mb, only concern i had is that the 1.8 fw and clutch weighs more. will i be able to lighten the 1.8 flywhell enough to make up for it. and still get the feel of a lighten flywheel?

Any other opinions before i order, would like to order tonight if possible.
So i don't have a choice of running a performance street disc on the 1.6 flywheel?
im just worried that running the 1.8 not only is going to cost me a bit more but will not yield the benefits of a lighter flywheel.
decision decisions....

I sound like a broken record and have posted this on four different forums with the same responses but here goes again.....
The lowest rotating mass (flywheel) is good for acceleration, reduces stress on the driveline and reduces vehicle total weight. It also reduces the inertial load that the clutch has to hold.
The only bad that I've encountered is launching a low tq vehicle with very sticky tires. I had Mickey Thompson slicks on my RX-7, with 200whp NA, 2420lbs going down the track, I actually bogged launching on the rev limiter at 9300rpms. A heavy flywheel would have taken care of this. That is the only instance in 21 years of running an aluminum flywheel as a daily driver/fun car that I wished I had a heavier flywheel.
I don't want to guarantee that this will work for anyone else, this is just my one data point but I've run the 1.6 Fidanza aluminum flywheel and the Exedy stage 1 (just one step above stock) for about 20k miles, half of that boosted. All of it with heavy R compound autox and dragstrip use. It doesn't hit hard but it doesn't slip. I think on the 1/4 mile vid I may have had a tiny chirp going into 3rd gear so it hits plenty hard for me.
Having broken u-joints and snapping a trans input shaft in the past, I'm a big fan of reducing driveline shock.
I admit that when it comes time to rebuild the motor I'm going to put in a higher clamping force pressure plate and a slightly more aggressive clutch (unsprung marcel but sprung hub and still organic). I'm hoping to up the power significantly.
