little bro is getting a pgm...

My brother is getting a grind machine and wants z stacks. will they fit?

Not too sure, but I think they fit if you take the weight rings out. ;D

Probably won’t…

They fit, but it vibes unbelievable and unplayably bad

my friend took the hubstacks off his pgm took z stacks off of a 2010 g5 and put the hubstacks on the g5 and the z stacks on the pgm and it worked

Dude, actually it was a complete faiure. It vibed way to much, it seemed like the yoyo was like 1 foot wider, and you couldn’t pick up the Z-Stacks.

It affects the spin time.

It works but it is not worth it. It affects spin time and has vibe.
