Which Flywheel, Pilot Bearing, Release Bearing and Clutch?
So, I've been going back and forth over whether to swap to a 700R4 in my T5 Formula. I've decided to stick with the T5, and I need a flywheel, clutch, pressure plate, pilot bearing and throwout bearing.
I'm just wanting a good Stage 1 clutch. I had a Centerforce in it for over 20,000 miles, and was happy with it, although it looks like the Centerforce throwout bearing failed. I'm going to need a new flywheel, pilot bushing, release bearing and clutch, and I want to get the best of each (within $$$$ reason).
THE CAR:
Exhaust and 3.42 posi aside, she's a stock L03. Makes 170 RWHP. Don't plan on ever getting over 300 RWHP, if that.
I'm not gonna race her, I don't do burnouts. I just want her to be my daily driver.
FLYWHEEL:
I'm thinkin I want to go back with a stock one. gmpartsdirect.com lists 2, but I don't know which would be correct. Both say " Without 305-g." Not sure what "without 305-g" means.

The aftermarket choices are a lot cheaper, but I'm a little concerned over quality.

PILOT BEARING:
I want to run a roller pilot bearing. Is there a better one than Dorman?

THROWOUT BEARING:
A buddy of mine raves about Hays self-aligning throwout bearings. Is that the way to go?

CLUTCH DISC AND PRESSURE PLATE:
I was thinking about the Spec Stage 1, But I only need the disc and pressure plate. I don't see them listed separately. https://www.summitracing.com/parts/s...model/firebird
a) Is that the best choice?
b) Where can I buy them separately?
Any advice is appreciated.

Is the clutch bad or just the TOB ? At 20k miles you should still have plenty of meat on it. Personally, I'd replace the TOB, inspect clutch, if nothing wrong, send it.

The clutch disc and pressure plate are OK, but when the throwout bearing failed, it left some grooves in the arms of the diaphragm on the pressure plate. The weights on the pressure plate were kinda janky, too.
I sent the disc and pressure plate back to Centerforce. They said they should be OK, and the issue I had with the weights were because the pressure plate wasn't bolted to a flywheel. I torqued the pressure plate to the flywheel and exercised the pressure plate several times, but some of the weights still didn't move as freely as the others.
The flywheel has been resurfaced once, and the teeth got chewed up pretty good by a mis-installed starter.
I've also been fighting both an engine vibration and a driveline vibration for years; it's why I had the transmission rebuilt in the first place.
With all that, I don't want to have to pull this transmission out again, so I'm going to start fresh with all new everything.

UPDATE:
Just talked to Ryan @ Hawk's. I've dealt with him before; he's never steered me wrong.
He's big on RAM clutches.
Here's their flywheel he recommends: https://www.hawksmotorsports.com/198...5-clutch-only/
Here's the clutch kit: https://www.hawksmotorsports.com/82-...-1-clutch-set/
He said he can do it without the pilot bearing and the throwout bearing so I can run the ones I want.
Thoughts?
