I have an 08 cobalt sport. full bolt ons now, but going sc as soon as I save up money for the clutch. This is my first stick car so I've never dealt with clutches before so I have some questions. I plan to only run stock pulley, and car is a DD. I won't be racing it all the time.
- I wanna get a Spec stage 2 clutch. Is spec good? Is there a better recommended clutch?
- Is it ok to use the stock flywheel, or should I get aftermarket? I hear lightweight is no good though. If stock, it must be resurfaced correct?
- Does trans fluid need to be drained when changing a clutch? If not is it recommended to change fluid anyway? Especially if I'm going sc.
- I should use Mobil1 Dexron ATF synthetic blend for the F23 right? It says on the mobile website "Mobil DEXRON-VI ATF is a high performance, synthetic blend automatic transmission fluid formulation designed to meet the stringent service fill requirements of GM’s Dexron-VI specification."
- What is TOB and do I need it? If so where do I get it?
- Clutch definitely needs to be re-bled correct? (sucks if yes I just bleed it 2 months ago what a pain in the @$$ lol)
- Do all new clutches come with an alignment tool or do I need to buy one?
Anything else I might need to know?

ya id go stage 2 then...i know of 4 guys personally who have had specs fail on them including myself and spec did nothing for any of us. but clutchmasters is a much better clutch
whooooooooa I don't have that kind of money nearly $800 and not including shipping that's how much I paid for my sc kit! No way I can't spend that kind of money for clutch masters absolutely not. I don't even have that kinda money after spending that much on the sc kit! Any other recommendations? It's bad enough the spec 2+ is nearly $500

I don't find that many posts with failing specs. In fact the most recommended clutches i've seen said in search was spec.
What about my other questions?

most come with an alighment tool
spec did not come with a new tob while the clutchmasters did.
no u dont need to change or drain ur tranny fluid to change the clutch
yes it will need bled after you are finished
it really dont matter to me with wat clutch u buy haha but im just saying a ton of people have had trouble with a spec and few have had problems with clutchmasters or kentucky clutch. if u want ky clutch u have to call and see if they even offer one for the f23

No one with a ZZP Clutch review yet huh man. Its between ZZP or Clutchmasters for me. ZZPs is way pricey, but there's gotta be a reason why it's pricey hopefully.
$854 plus shipping and install for the ZZP.
But I figure an extra $300 isn't that bad for reliability and performance over the clutchmasters, but then again, if clutchmasters does what I want it to do, feel stock and be reliable then why spend the extra money.

and the stage 1 is constantly outta stock for zzp. i work off tips i cant afford an 800 dollar clutch it'll take months to save up not to mention bills i have to pay on top of trying to save. It took me 2 years to save up $800 for the sc kit... I'm thinking of just saying f it and stay with stock clutch. Buddy with 2.2 has 85k on stock clutch, just SC'd with 2.9 and its holding up fine even at the track so why stress my self out over the clutch now?
Questions left:
- Is it ok to use the stock flywheel, or should I get aftermarket? I hear lightweight is no good though. If stock, it must be resurfaced correct?

i agree ive had nothing but problems with my spec stage 3+ and light weight flywheel. Come to find out my light weigth flywheel is made wrong and thats y i kept blowing out slaves. Over all it does hold the power but to many head aces. Some pepole have do not probs with the set up. i have but i guess im the unlucky one lol this is on my lnf. i think if u stick with the stock flywheel and use the spec stage +3 clutch and pressure plate u will be fine.
Either fmywheel has its ups and downs so its ur choice
Tob is the throwout bearing which engages ur clutch when u hit the pedal and yes u need one
All I k ow about the tranny fluid I remember it is automatic tranny fluid but not positive on wat kind

Kentucky Clutch Stage 3
Six puck Kevlar/Ceramic
Stock flywheel
Stock slave cyl.
Installed slave that came with kit, but it was a bad slave and leaked. Had dealership install the stock slave and it's been great since. Engagement point is great, just like stock. Clutch has been very streetable since day one, except when the slave was leaking. Love the clutch!

I think the exedy stage 2 would be good for you. I have nothing but high praise for exedy, just wish they made something to hold my power
I don't think so, if they had adj. zzp rod they could move it down if it was a problem
