gmpp and stock LNF clutches are basically the same (as in, you wouldn't tell the difference running them). here's a good thread for reference: https://www.cobaltss.net/forums/driv...rences-283279/

the gmpp will mate to the spec lsj flywheel. the spec lnf flywheel has thicker dowel pins, but is otherwise the exact same. the stock LNF flywheel will mate to the LNF flywheel. The GMPP clutch will mate to an LNF flywheel if the holes are bored (I could be worng here, I haven't done it). since you should be getting a new flywheel too (that's a debate best searched rather than started again here), buy the combo that makes the most sense price-wise. the linked thread brings this up too (Powell Race Parts is an excellent source of information).

It's similar to stock, there has been a lot of back and forth on it over the years as it being the same. Believe the pressure plate is the same but the gmpp disk is a little different. Both will work whichever you do. How long it lasts is up to you. There are guys who got over 100,000 miles out of their factory clutch.

Little late for a response, but I'll just add my $.02

As Nova said, there has been debate on the GMPP, but other than the color of the friction material of the disk and the springs in the hub, they are basically identical. The only difference worth noting is GMPP is technically rated at 420tq at the flywheel(was on CrateEngineDepot).

The holes in the GMPP pressure plate are larger, and meant for any flywheel based on the LNF. The LSJ flywheel has smaller dowels, as do any based on it, requiring a little extra patience centering it. There is a good picture showing how to use a BIC pen cut into 3 pieces to assist in centering.

I've been keeping a long term update going on the GMPP paired with a LuK fluwheel. So far the combo is just shy of 30k and going strong, with a little more than half on fbo stock turbo and a little less with a Z54 on it.
