The clutch on my 2000 Z28 is slipping badly. It's the original clutch with 106k miles on it. I plan to install the following components:

12570806 - LS6 Clutch Kit With Pressure Plate, Disc & Flywheel
24264182 - Slave Cylinder / throw out bearing assembly

Questions:
1. Is it advisable to replace the Master cylinder also or is the stock 2000 one good enough?
2. Can original (106k mile) flywheel just be resurfaced, or do those typically wear enough that it would warrant just being replaced?
3. Any other parts needed to complete this job (other than clutch and trans fluid)?

Any input would be appreciated!

If you haven't bought your clutch etc I might have all you need except throw out bearing I'll make a good deal on.

The stock master will require replacement

Can you PM me with what you have and price?

Thanks.

Thanks. Can you elaborate? Is the stock '00 master cylinder a weak point that would typically fail after a lot of miles? Any improvements with the later '01-02 master cylinder?

The OEM master cylinder has trouble shifting at high RPMs. If you're just daily driving the car you'd probably be ok with a drill mod on the stock unit, but IMO the tick unit is one of my favorite mods, it completely changes the car. Also do a remote bleeder, you'll thank yourself later.

What black said. I went through several stock masters. Including two 02's. Then I sprung for a tick. The F body clutch hydraulics were hamstrung to protect the Barbie 10-bolt from the LS1/T56 one-two punch. As long as everything is brand new it's ok for a while, but that's about it.

Centerforce

If the flywheel isn't warped or damaged, you should be able to have it resurfaced to flat. You should do this any time you replace the clutch and make sure that it's being resurfaced on a qualified flywheel grinding machine rather than a lathe or blanchard grinder or a handheld electric or pneumatic grinder (Yes, people try that).

Is the ls6 clutch sold without the new flywheel? I suspect mine is in good shape, but may be more trouble than it's worth to have resurfaced

Have you considered like a monster stage 1 or other kit that comes with a new flywheel?

Centerforce

It depends on which Centerforce clutch you want. The DYAD systems come with everything (pressure plate, clutch discs, floater, flywheel, bolts, etc.) but the Dual Friction, DFX, and LMC clutches can be purchased as a pressure plate and disc but don't come with the flywheel, which we do make as well in steel or aluminum.

Part numbers if you want to look up pricing on any sites:

LS1/LS6 flywheels:
700142 (Steel, 29.7 lbs.)
900142 (Aluminum, 13.1 lbs.)

DYAD:
04614842

I can get part numbers for the LS6 Dual Friction, DFX, and LMC clutches (Click here to see applications/characteristics for them) if you want them. We have 12" (for forced induction and nitrous) and 11" (for NA) clutch discs/pressure plate setups.

I think I have all the part numbers for the clutch swap on my '00 Z28. I'm going to go with all stock/GM parts. Is anything else needed other than what's listed below?

Master Cylinder (01-02 upgraded): 12570277
Slave Cylinder (01-02 upgraded): 24264182
LS6 Clutch, Pressure Plate, Flywheel: 12570806
Pilot bearing: 14061685
Pressure plate bolts (quantity 6): 12561465
Flywheel bolt (quantity 6): 11569956

don't waste your time on an OEM master for the fbody.

CoolAid

I get that there is a sycophantic following for the $325+ Tick, but the stock master doesn't need to be replaced. Especially from the sounds of this not being a heavily beat on or frequently drag raced car.

You can get an entire LS7 clutch setup including slave, pilot bearing and rear main cover for under $470 from the right place with the right p/ns if you are interested. All you'll need to add from elsewhere is 6 of those flywheel bolts you already listed.

I hear you, but some of us have gone through several stock masters in a short period of time, and the tick master resolved it once and for all.

After three GM master replacements in 12 months - and the PITA that is hitting those firewall holes - I had no problem forking out for the tick to NEVER have to worry about it again.

Call me sycophantic all you want, but my own personal experience made me a fan of tick.

Flywheel and pressure plate bolts are reusable, to save a little coin, but new ones are relatively cheap insurance.

Just make sure to use thread sealer on the flywheel bolts if reusing them.

Is GM part # 12570806 (LS6 Clutch kit) identical to LUK 04-905? I've seen conflicting information on this, so just want to try to understand that. Preferably anyone that's installed this LUK part, it would be good to hear firsthand that it is in fact the same. I believe LUK was the OEM supplier for clutches so my guess is it's the same.

LUK 04-905 is about $100 cheaper than GM 12570806 and the LUK kit also includes an alignment tool, throwout bearing (but not slave), and flywheel bolts.

The Luk 04-905 is the LS7 clutch kit.

Others have said that as well (hence my question), but on LUK's site, they list LUK 04-216 as the clutch for '06+ Z06 (LS7).
