Got a SPEC Stage 3 for $100. Got a question
So my friend spun a rod bearing on his LS1 only a couple months after a new SPEC Stage 3 clutch install. He swapped a complete drivetrain into his car and I was able to get a deal on his old clutch - $100!. He said it had no more than 2-3,000 miles on it, and it looks in great shape.
My questions:
-Will I need to run a shim on this?
-I think I want to go with a SPEC steel flywheel with this.. Should I and why?
-I'm gonna need to get a new TO and new pilot bearing with this right? It's missing those

The parts looks pretty good to me. You should use the shim, as well as a new TOB and pilot bearing. As for the flywheel, it would be great to use our flywheel, they are afterall designed to work together. Give me a call if you like and I will be happy to assist you with an order, or you can contact any of our dealers. Let me know if you have any further questions. Thanks,

Thanks for response. So you think the parts do look healthy to use? Is there a certain size shim I need to order? How much would it be for a shim TOB, and PB? Also, what am I going to notice differently comparing a stock resurfaced flywheel to a SPEC Steel flywheel? (I don't want to go aluminum)

It's best to measure to see if you need a shim (there's a thread in this section explaining how to do this, search for it) rather than just throwing one in blindly. I run a spec 3 clutch on a GM flywheel and even though Spec recommends using a shim, mine slipped terribly and wouldn't completely engage with the shim installed so I removed it and it's perfect.

After some thought, I think I may switch to an LS7 clutch setup with aluminum flywheel. I can tell I'm gonna be needing a new clutch soon. I am hoping to avoid problems in shims, chatter, and on/off like driveability. I really liked my Stage 2 I had in my old LT1 though, but it was a full face disc.

So I'm on the edge of this back and forth. I'm thinking I may stick with the clutch, buy a RPM Speed billet flywheel, new slave, TO bearing, and pilot bearing. With this thing already broken in, it should be pretty smooth. I can have the new FW and clutch balanced before I even start the clutch install. I know I'm gonna be needing a new clutch soon. Mine is soo spongey. I'm betting its stock 100k mile clutch.
How would the RPM Speed billet flywheel and SPEC Stage 3 clutch cooperate together?

Ok I'm ready to buy the rest of the parts that I need for this clutch. I'm planning to get the RPM Speed Chromoly flywheel, new GM 01-02 Slave, New TO bearing, and new pilot bearing... I guess I'll need to buy a few shims from SPEC just in case I need to shim it.. What sort of shims am I looking for? A multi-pack or something?
Anyone have any experience with a SPEC Stage 3 or similar on the RPM Speed flywheel???

Since you are using a new flywheel you will have to break-in the parts. Remember it is all about seating the materials. I am not familiar with this brand of flywheel though so I can't comment on it specifically. We offer two shims, one is the .115" and the other is .188". You can reference the link below to determine which shim you need in advance.

Let me know if you have any further questions. Thanks!

Hmm.. After looking I see the SPEC Steel flywheel for only like $25 more. How much does it weigh? I don't want to go super lightweight aluminum, but I want a lighter flywheel. If it's lighter I'll go ahead and get the SPEC flywheel to keep the brands matched..
I guess I'll call you soon to have the shims ordered to have on hand while I install it.
And also is the throwout bearing part of the slave cylinder? I'm used to LT1 transmissions, where they are much different.. Never been inside an LS1 trans

The shipped weight of the flywheel is 26-lbs, while the raw weight, without the packaging would be 24-lbs. I have shims available. If you are buying a slave from us the bearing would be included. I have all of this on the shelf so just let me know if you need to place an order. Thanks,
