Exedy twin usable service thickness

Hello everyone, I have an Exedy twin in front of me that measures between 2.8-3.0mm on each puck on both the upper and lower disc. I've been reading that the service limit is about 3.0. Are the discs toast and require replacement or is there a way to make this work as is ?

I also have a freshly resurfaced act flywheel with m018 pressure plate. Was looking at a sprung 6 puck for dd use in about 500whp/tq range. I've read that this combo is good for a little over 600tq. Thoughts ?

They're at/below the service limit, they needs to be replaced.

By the book it should be replaced. But... I dont know if its legal in US but here we have guys that "put" additional layer of kevlar on it so its stronger and you can reuse it If you didnt grind those springs already it could be done.
