Default I'm new at the clutch business.

I plan to put a head/cam upgrade on my 02 SS soon, but I want upgrade the clutch first. It's the stock M6.

I've heard people say upgrade to LS6 or LS7 clutches. What does that mean?!

I'm shooting for 550rwhp and 500rwtq after I finish my upgrades, so I need a clutch that can stand up to the task.

Opinions please!

Thanks

I've heard people say upgrade to LS6 or LS7 clutches. What does that mean?! The GM clutches used in cars with those engines with higher horsepower engines had pressure plates with a higher clamping force and therefore the ability to withstand the extra torque. The LS6 engine puts out a GM advertised 405 flywheel horsepower and the LS7 is 505.

I'm shooting for 550rwhp and 500rwtq after I finish my upgrades, so I need a clutch that can stand up to the task.

Opinions please!

Thanks
If you're goal is to be laying down 550/500 at the rear wheel, that translates roughly to somewhere in the neighborhood of 650 hp at the flywheel, so I would say you might want to forget the LS7 piece and start looking at a dual disk unit. There are several different brands to choose from.

I've had great success with the McLeod 800 clutch.

My engine is not quite what you intend, but it's fairly strong.

The pedal feel is pretty much stock. An increased surface area
really helps transfer the power. There is a noticeable difference
when slipping the clutch, and power shifting.

My car went from chirping the 1-2 shift to fish tailing, and even
chirping the 2-3 shift. Not ideal for racing, but it really highlights the
amount of slip I used to receive on a stock clutch.

Here is a comparison of the disc overlay:

The more aggressive you go with the clutch, the more driveability you lose. So first, you need to figure out what exactly you are doing with your car. Are you planning to race your car at the track? If so, then how often?
As for the LS6 clutch, it is nothing more than a stock replacement clutch. The LS7 is a stock clutch for a 2005+ Vette, which is a little better than the LS6. Still not going to handle the power you plan to make.
I offer a complete line of LSx 12inch clutch kits, see the link in my sig. My Stage 1 kit is a step above the LS7. The site has a good FAQ to help answer some of your questions. Hope this helps!

Hey, there you go. There's one good option right there.

Hey, Jason! What's up?

You need to answer the following questions:
1) How important is a light pedal?
2) How important is lack of clutch chatter?
3) How often are you going to be at the track?
4) How much money do you want to spend?

I would definitely NOT buy an LS6 clutch. LS7 is cheap and will hold 450+ RWHP but race much at the track and it's not the best option. A twin disk clutch will hold a lot of power, drive like stock (no chatter and and have a light pedal) but they're not cheap. Monster is a popular and affordable clutch lately but it's a puck style that's more prone to chatter and will have a little bit stiffer pedal. I would also recommend that whatever you buy to definitely replace the slave cylinder with a new GM piece and also upgrade your master cylinder to a Tick adjustable unit.

RPS carbon twin disk just got some good comments recently from one of the mods here who installed it in his car.

Ok a light pedal isn't a big deal, but the chatter is what I don't want. I'm not going to be at the track much, but I do want to kill any Mustang I might meat at a red light. Money is not an option.

Thanks for the info on the LS clutch upgradesand everything else.

I have looked at dual disc set ups, too. I guess I just haven't made my mind up yet.

If you don't want chatter at all then I would go with a full-faced disc. Spec makes a stage 3+ and a few others make some lower stages that are full-faced. However since you want 500+ RWHP then I would stay with a stage 3 or larger so you're going to be limited on single-disc clutches that don't chatter. The other option is a dual - my McLeod twin doesn't chatter at all and it drives like stock (except it actually holds my power). You can actually run a McLeod RST twin that's good to 800HP with a stock LS flywheel to save a little coin. I spent around $1200 for the dual with a billet steel flywheel, pilot bearing, and slave cylinder. I'm waiting to beef up my differential a little bit before I take it to the track and test out the new clutch.

Ok cool. I like the idea of a twin disc setup with the stock flywheel. Being flexible to add a little more power later on without having to beef up the clutch again is great too!

A twin disc is complete overkill for what you have.

It is for now but he did say he wants to be at 550+. Hell I'm not even at 500RWHP and I'm very happy with my decision to go with a twin. There are other factors to buying a clutch besides how much power it can hold. Speaking of which is Monster ever going to release their twin?

It might be overkill, but I'd rather have overkill than a blown clutch I just dropped a grand on. I just want reliability and to know that my clutch isn't going to crap out when I need it most.
