Clutch talk
Well I'm now looking for a clutch to install by the end of this year.
What are you guys using these days?
Currently my set up is a stock c5 LS1. Motor mods will happen within the next 2 years such as cam and valve train etc.
So I drive my C5 on a daily and do some pulls from time to time and car is holding up pretty good.
I read the ls7 is a good way to go but what do you guys think of the Luk LS7? Correct me if im wrong but isn't LUK an OEM?

An LS 5 series? Fking sweet man. E39? I've got a friend with an E39 530i Sport 5MT who's looking for something like that. Car has over 180K and it won't die. But if it does I have to convince him to go LS.
Got any pics or info?

I've had an LS7 clutch and flywheel for about 10K miles now and I'm very happy with it. A little stiffer than stock but I really like the feel. I'm at about 342 rwhp, so there's plenty room for more if I want.

I'd suggest getting a lightweight flywheel with the ls7 clutch/pp combo cause that thing weighs a ton. An aluminum flywheel brings it down to the weight of a stock ls1 clutch. Several vendors sell an LS7 clutch kit with aluminum FW.

I'll vouch for my setup being factory street easy while also being able to handle power.
MacLeod RST which is rated to 800tq and easily upgraded to eat status if needed. Soft pedal like new.
Finanza lightweight 11lb flywheel. Rev matching when shifting is instant now. I've seen no issue off the line. Though now I am near to finishing a new used with a blower, so results may change.
Definitely recommend:
Tick remote bleeder
Tick master cylinder (pedal remains light, engagement becomes adjustable and way less travel)
Remember to replace or upgrade the torque tube couplers
And if not already done, an MGW shifter and Gripper **** put you in good contact with the machine.
For $1 and ten minutes or less of time, go ahead and do the anti venom mod. Single ring makes it perfect. M20x3/4" copper washer on the detent plug. Takes the notchy out of finding gears.
Aaaand... You're good.

I have the ls7 clutch on a stock ls6. I DD it and have ~5k on it. Works great, no slip and it feels like the stock LS pedal felt. Do yourself a favor and get the remote bleeder and tick master cylinder. Great feel and adjustable settings with the tick MC. If I were to do it over again, I'd get the Al flywheel.

I have zero hands on experience with LuK. That said, I hear very good things about them for oem style replacement. It's a good price for the kit. Just get a remote bleeder and at least a new slave cylinder TOB at the same time.
Double check that it comes with the flywheel. The ls7 is dished and our factory ones are not. The picture showed one but I did not check the item description......

This exactly. In my 6.0 LS BMW the 18lb steel flywheel revved quickly but was uncomfortable to get going, you'd have to blip it a couple times to get the big heavy body off the line at a red light. Not launching it mind you, just regular driving. It was also annoying when shifting slowly through the gears because the revs would drop below the point appropriate for the next higher gear, so you'd have to give it a tiny blip if shifting slowly, bring the revs back up.

The only detail which stands as unproven and would vary by car/driver is the 60 foot dig. Common sense would suggest that more rotating mass revving prior to launch would equate to more force hitting the drive train and tires, but I have never seen real world comparison of an average of several launches before/after on a car with everything else being equal. Still... Maybe worth .1?no way of knowing.

What is that flywheel originally intended for? Says it won't fit my 97 vette? I've been trying to decide between the luk ls7 clutch and just a standard luk clutch. for everyone with the luk ls7 clutch, did ya'll have to do the air gap measurement? Did you guys get an adjustable master cylinder? Thanks.
