Centerforce vs. Ram vs. LS7 I am looking for a clutch that will hold ~420ish rwhp and solve my sticky clutch issues. I am VERY torn because there are so many good/bad threads about every clutch made lol! I don't go to the track and still have a 10 bolt. I am told the spec stage 3 would snap my puny 10 bolt. I want it to last awhile and I only do some mildly aggressive street driving. Right now I'm considering 3 clutches: 1-ram power grip(non-hd), 2-centerforce df(12") and 3-LS7. Not sure about the ram.......I haven't heard quit enough good things about the centerforce to put me over the edge........and the LS7 is still too new and kind of heavy. Any recommendations?

He said it still sat a little low but engaged fine up in the high rpms. He did not have an adjustable master.
I'm going to install mine with the shim of course, and get a 1000 miles on it before I decide whether I will need the adjustable master or not.
Hopefully not. :fingers crossed:
BTW, figure the aluminum is a good 15 lb weight loss (13 vs. 28 comparing old ls1 flywheel wieghts, assume they are similiar) so even with the 8 lb heavier clutch it'll still be a good drop. Actually, I was anticipating this so hoppefully the maladys that people typically have with the alum fw (bog, hard to launch) will be minimized.

Does this Shim come with the kit?
Where does one locate the proper shim?
Which lightweight flywheel is best to use with it?
Who is speaking from experience and who here is just recycling someone elses information?

I'm speaking from personal experience, but I just bought the parts and Next Level Performance did the install. As already stated, I had the Fidanza LS2 flywheel (p/n 198171) installed with my LS7 clutch. NLP already had the shims in stock, they are not furnished nor available from GM nor Fidanza. I heard the shim comes in a pack from SPEC, but I believe they're all the same thickness, ~.0150.
The only lightweight flywheel I know of for the LS7 is this unit. Perhaps something else has arrived on the market in the last few months? I was using a Ram HD the last two installs with their 18lb billet flywheel. I can't tell the difference in that 5lbs, but I don't drag race either.
Per NLP's success with the latest GM hydarulics, they recommended I remove the McLeod adjustable master I had been using the last few years (and completely rebuilt less than a year ago) and go back to stock hydraulics and I requested they bore out the master line.
I still don't particular care for the engagement point. It hasn't come up during the course of break-in for me as others have reported.
Steve (aka MeentSS02) - you're somewhat close to me so if you were curious about checking it out in person, I'm sure we could arrange something
Edit: There's a guy at Speed Inc (John, maybe?) who has the same setup as I but used an adjustable master instead of the shim. I was tired of the clutch pedal height and couldn't decide which was the bigger hack - the adjustable master or the shim. I decided on the shim because I wanted the brake and clutch pedals to be at the same height when released. I could get the engagement point where I wanted it with the Mcleod, but then the clutch pedal was 1/2-3/4" higher than the brake and I didn't care for that.

I think I'm gonna get the LS7 clutch. I drove a car with one in it last week, and it was perfect! It grips like crazy and the pedal pressure was as light, if not lighter than my late model LS1 clutch. No chatter and very smooth engagement. It drove just like a stock LS1. There also seems to be quite a few guys with serious hp, abusing these clutch's with great success. I'm sold!
