Based only upon the pictures in the OP, the shock buffering springs in the two discs appear to be different. Not because the colors are different, but to me it looks like the top picture seem to have smaller coils which are wound tighter. That could just as easily be an illusion based upon two different sized pictures take from different perspective. It would be good to know though.

flywheel is irrelivent, they both have the same part number, my lnf flywheel bolted up to my gmpp clutch kit. Get it from zzp, they are the cheapest for flywheels.

For a flywheel, is it better to stick with a stick one, or lightweight?

For DD go with stock

smart. Right thing to do. Too bad your spring choice is what it is lol

09BlueBaltSS

^^^ never mind. The CM rears will fall out for you after time...troof. I was shocked when it happened to a customer. brought some used ones to install... its sort of self serve spring change...lol

Alright thanks! I'll get a GMPP clutch for my TVS and keep the stock flywheel

So to be clear, the GMPP clutch you all speak of is the LSJ Upgrade clutch available from CED?

Ecotec LSJ Clutch Upgrade Kit 19212712

I was on the fence between a stock LNF clutch and a KY Stage 3, but wanted to consider other things in between... it seems like from what you guys are saying GMPP clutch will bolt right up to LNF transmission and work with LNF flywheel while holding up to 350-380 WTQ?

c130aviator

Its unbelievable that the GMPP kit is so cheap. But I had a 600 dollar SPEC clutch for my engine build. I ended up selling it, getting the GMPP and made 420 hp on it and it never gave out. Awesome product for an unreal price.

springs falling out also have to do with incorrect shock height. I used to build jeeps and trucks before getting into my cobalt. Solid axle swapped a late model bronco, built 3 jeep wranglers with lcog suspensions, and never bought a kit, always assembled the syetem with parts of my choice. CM springs are a great dd spring, dont sell em short because someone didnt know how to set up their suspension correctly.

I have CM springs. Havent fallen out. Great ride

c130aviator

i have cm springs as well, great ride and still firm enough to feel like you are on a better than stock spring.

My CM springs are en route... Heard nothing but good things about them (except from John, but that's to be expected, they're competitors). The YYZ and CM are not even in the same category.

YYZ are great PERFORMANCE springs handles way better than stock, almost no drop...

CM is a good LOWERING spring. Decent drop. Handles close to stock.

YYZ=$322+shipping

CM=$179 shipped


I don't track my car, just drive it spirited on the street... As far as the clutch goes, I think I'll go with GMPP. It sounds like it's a little stronger than LNF stock clutch, but a bit lower than KY Stage 3 clutch... $260 cheaper than KY clutch too...

I will give you my opinion on CM Springs

I sold them and got pedder springs.

Now I'm happy

serega12

iTrader: (1)

Brand new pedders?

For now CM is good for everything I want the car to be and do. If I keep the car long enough and decide to invest in suspension, I'll get YYZ v2 (or v3 by then, who knows) and Koni Yellows.


As for the clutch, I just ordered GMPP clutch...

c130aviator

Now get rid of that k04 and be faster than you will be even happier.

This is what it sounds like when everyone thinks their parts are better than the other guys. CM is the dominant spring in the cobalt community for a reason.

vahdyx

I liked CM Springs initially, but as the days went on, I didn't like the quality of the ride anymore. I went to (yes new) Pedders springs and I was surprised how much more comfortable the ride was. Granted the rear doesn't look very low, but to me the stance isn't that bad.

You tell me what you think?



I too will be ordering my GMPP Clutch next week. I will hopefully install it next weekend. I'm gonna see if a local Cobalt owner will help me install it. I'm scared because I normally pay people to work on my car so it'll be a good learning experience, but my pessimistic side thinks it'll break or I'll install it wrong.

How do you plan on installing it?

vahdyx

iTrader: (7)

haha, no thank you. I'm perfectly happy with 360whp in my K04+. I don't wanna be any faster and if I get that bug, I'll just throw in E85 and get closer to 400whp. Speed isn't everything to me, but I do enjoy it, there's other priorities for me.

I don't think CM Springs are bad, I just didn't like them as much as Pedders, but my CM springs were significantly better than my eibach springs. I hated the ride on those.

c130aviator

360 is the most you will ever get out of the K04, you wont get near 400 with it. Go look at the dyno thread with "k04 power". Push it much harder and you will be like the ummteenth LNF with "rebuilding" in their signature.

As for Pedders I really want to try a set if they are better than CM's that is saying a lot in my opinion.

vahdyx

iTrader: (7)

I don't have a "K04" I have a K04+, they're a little different. I'm making 360 on 91 octane and I WILL get closer to 400 with E85 and no I won't be including "rebuilding" in my sig to do so.

***edit***

And in that dyno thread I am #9 (with Trifecta, now HPT) and should be #3. I'm aware of the thread and I will be the only one running pump gas in the top 5 and with E85/47 I can be number 1.

*** Back on track edit***

Which I hope the GMPP Clutch will hold

I would like to rebuild the clutch myself, but with full time work and school I'll have to pay someone else to do it. Pkus the car broke down 207 miles away from my house... That doesn't help it either.

As far as springs, CM seem to get pretty good reviews for what they are, so I'll give them a shot.

c130aviator

iTrader: (8)

i hope you hit those goals, just dont feel the header/exhaust side of that stock turbo housing will flow enough to do so. I wish you luck if you get crazy with it. GMPP clutch will hold. I have the same clutch. Edit: my dyno graph is up on the 2012 dyno thread. Waiting for mods to post it up. I will be #7 on all out power on the LSJ.
