    Anyone have any experience using the Zoom HP Kevlar clutch? I am getting ready to order a kit, and it is between the Centerforce Dual Friction and the Zoom Kevlar. I had been leaning heavily towards the CF DF until I read on some Chevelle and GTO forums that a lot of folks are having some quality control issues with the newer CF stuff. I know the Zoom Kevlar is popular with the Mustang crowd, and supposedly Kevlar has some great holding force and wear life, but I don't want to be a guinea pig. :rolleyes:

    Have you looked at the McLeod 12" that bolts to the stock GM 11" bolt pattern?

    Good call, I was just reading about that clutch over at Team Chevelle.

    The more I look into it the more I think the 12" McLeod stuff is the way to go. Light pedal pressure, works with stock flywheel, and huge increase in friction area.

    It will be a bit more pricey, but it will have better holding force then just about any other clutch option available short of a dual disk setup, and with the bigger clutch disk it should handle a lot of abuse. :3gears:

    I just requested a catalog from them, but I have read the best way to figure out what you need is to call and they will give a recommendation based on your vehicle. I'll be making that call tomorrow. :Brow:

    I know I'm not directly giving you the answer you want but I just put in a new centerforce dual friction clutch this past july. The only problem I had was that I used the stock pivot ball which was too small and never gave me the correct pedal height nor feel. Finally 2 months later everything binded up and I had to drop tranny and bell housing to install a lakewood adjustable pivot ball. I basically set the height by visually making sure the pivot ball was about a quarter inch highter then the stock ball. Then I put bellhousing on block and made sure the fork throwout bearing assemble wasnt touching flywheel but just a fraction off of it, as soon as you barely push fork it would touch clutch disc. Then i bolted everything up. Once the throwout bearing self aligned I guess, still felt funny till I pushed the pedal up and down a few times and something snapped into place, then the pedal was perfect. still feels great and I havent done any adjustment of the adjuster rod which by the way leaves plenty of room for adjustment, with the stock pivot ball it was all the way at the end with no room for adjusting. Pedal effert is good and the clutch holds perfect. Hope that helps if you go that route.

    Nothing is set in stone yet and the only reason why I have been shying away from the Centerforce is the upswing in problems I have been reading about. I have had experience with the CF in my old Mustang and in my Father-in-laws (Joecool) 69 Camaro. Both worked flawlessly, but both were behind small blocks.

    I really like everything about the CF except when I read about a guy having to put 3 of them in his GTO before one worked correctly. That and the problem they seem to be having with the centrifical weights not returning to center, causing vibrations, and odd ball clutch problems.

    Hearing that your not having any problems is good news and will make me think a bit more, even though I am strongly leaning towards the McLeod assembly.
