Default Running ACT ZM1-XTSS clutch, which flywheel should I run

So I’m installing a ACT ZM1-XTSS clutch on my 250hP turbo Miata. I am not sure what the torque is currently on the car.

Just curious with those of u who have run this clutch, what kinda of fly wheel did you run with it? Stock or lighter?

Again the cars turbo’d an it’s basically a daily driver. No canyon runs, a lot stop an go traffic, probably auto cross the car later this year.

I’ve been searching, a lot of people ran a 1.8 stock fly wheel with my setup. I’m leaning towards that.

My miata is a 1.6 with the XTSS, will I have any issues putting a 1.8 fly wheel in a 1.6 XTSS clutch?

i also read about lightening a 1.8 stock fly wheel? What’s that about ?
