Question SPEC Stage 2+ SAC OEM-style clutch versus non-SAC billet?

Hello out there. I'm swapping out my stock clutch/flywheel for the SPEC stage 2+ and lightweight flywheel combo. I was going to go with the OEM-style clutch but the vendow emailed me suggesting that the non-SAC style is better. I haven't a clue so I'm hoping some you have an opinion on the matter.

So... given the choice, which would you go with?

OEM-SAC or non-SAC

SAC stands for self adjusting clutch. all i know about it is that a SAC clutch automatically adjusts fluid pressure and level on its own using brake fluid or something to that effect.
In short, its probably an oem feature not necessary for a high performance clutch.

i do know, however, that the billet pressure plates are much lighter and MUCH stronger as far as clamping loads are concerned. exedy has billet pressure plates, as an example. stamped steel pressure plates are a very popular option, and may be cheaper that billet, but the billet is superior.

hope that helps

NON SAC is a much better setup. GM switched the new SS/TC clutch kits to NON SAC

BTW let us know which setup you would like, they are both the same price, we only list the SAC setups, but you just have to let us know you want the NON SAC and we will get you hooked up. We also price match on SPEC items, if you would find a better deal.
