If you've got the coin, get the Exedy.

LOL I don't have that kind of coin. I have about 3k to do upper and lower pulleys, clutch with slave, motor mount, trans mount, shifter, and tune. I do all my own work except the tune (i don't have the software yet)

McLeod RXT or stick with the complete LS7 kit.

Or the McLeod RST

http://www.mcleodracing.com/products/RST+Twin+Disc.mcl

This is the one I'm going with for a street use. Handles 800 HP and strongly recommended by my local speedshop.

Ok on the RST and RXT what do you use for flywheel and slave cylinders?

Many have installed the RXT and rave of the results - I'm sure some forum warriors disagree with my choice using the RST. I haven't touched mine yet. My parts list includes using the steel flywheel (33lb) and the LS7 slave - The flywheel choice is strictly for drivability.

So just a stock style ls1 flywheel and an LS7 slave?

This is the McLeod flywheel I was suggesting:

The LS7 slave or aftermarket equivalent can be used. Here is the aftermarket:

Again, I haven't installed this yet but this is my direction.

The RST and RXT are nearly the same, with the RXT having different friction material so it will handle a little more power and launches. I got the steel flywheel as well with the RXT. They're still a little pricey, but these have been abused by a lot of people and everyone raves about them. I have yet to put mine in though. Hit up Fuzzy...he already installed his and can give honest feedback.

I have the RXT in a supercharged vet that gets severely abused and that has been going well so far this summer. I also put the RST in the V (06) but had to pull the trans back out right away before getting many miles on it (synchros are going out in the trans as well). I put aluminum McLeod flywheels on both setups. If your slave is in good shape use it, Tick makes shims for it to get the proper A dimension. McLeods customer service is top notch and very helpful.

I need a point of clarification please..... So as I read through numerous threads about clutches it looks like an LS1 flywheel and mcleod twin disc with ls7 throw out bearing will fit? Is this correct? Can someone who has it please confirm?

I have a parts list b/c I'm going this route - it's on my jumpdrive at work. If nobody responds by tomorrow, I'll share my clutch parts list on this thread.

That is the same combo that I have about to go in...if you can wait a few days/week I can get you confirmation. Trans won't be here until then.

That would be great if you could do that.

That's fine I don't NEED one right now it just slips if I'm really out thrashing it. Thanks

Get a Monster Dual Clutch!!

I'll be putting mine in after next weekend.
I have a 18lb FW and Monster says this setup weighs less than my previous setup. Less rotating mass....yay!

Plus it looks amazing, and that's all that really counts....

Monster left such a bad taste in my mouth, I will never use nor recommend them.

To be fair, I used their "puck" clutch and from all the info I could gather, puck clutches will chatter.

NO KIDDING!

Here is what I got for my troubles:

1. Chatter never went away resulting in two sets of rattled apart spark plug wires that fell apart when unplugged.

2. Chatter caused headers to vibrate loose, resulting in leaks and blown header gaskets.

3. Was embarrassing to drive, at least from a stop.

4. Although they were not torn apart, I replaced the motor mounts as I knew they got stressed.

Ya I'm replacing the puck style Stage 3 with the twin. Should be night and day difference.

Yeah I have looked at them but read to many bad things about monster to use one....... Granted I have heard lots of good things too but......

I went with the LS9 and it feels like stock.

The chatter was so bad with the Monster I couldn't wait to yank it, after giving it a year to "break in".

I have a Mcleod twin RXT....U need to get THEIR slave with their self adjusting ring...Their slave came with a long self bleeder..cost $540.00 just for slave to make an RXT work...:alchi: Call them.....

ps: I think the Mcleod was a waste of $$$$$. The clutch chatters badly...I have to start off in 2nd. gear.......Thinking about getting again the KATECH CLUTCH......

I think there are different outcomes with the McLeod RXT (and RST). I was leaning towards the McLeod RST but changed directions and thinking the LS9 Katech clutch. It has more to do with street drive-ability and the prices are not so much different.

I have the same clutch. Got a slave and bleeder from O'Reilly's was like $100. My clutch chattered a bit at first. But now not really. Not sure if its my driving or the clutch. I will say though it likes to grab so there isn't much feathering the clutch. You want it in or out... I wouldn't call mine a waste of money at all.

I love the guys that create a new account to trash a product. Fortunately, it's easy enough to match you (http://ls1tech.com/forums/17495328-post23.html) to your (http://ls1tech.com/forums/17496177-post25.html) similarly amusing (http://ls1tech.com/forums/17433734-post16.html) tales of woe on LS1Tech (http://ls1tech.com/forums/17521411-post5.html).

I'm sorry that you don't know how to install a clutch and wasted $550 on a premium slave trying to rectify the fact that you or your mechanic can't assemble the clutch OR install an engine OR wield a torque wrench. But that's no reason to try to potentially mislead other CTS-V owners.

The McLeod RXT is a spectacular clutch. I've been running it for about 500 miles now, and while it will certainly give me a touch of chatter in the first one or two engagements given just the right combination of temperature and humidity, that's an unavoidable characteristic of twin disc clutches that you either need to learn to accept, or plan on never exceeding 650 RWHP.
