Hey all, in the midst of getting my clutch done. I'm getting the stock flywheel lightened and balanced and going with the Cup clutch disc.

I'm torn on the pressure plate. I'm going to have Vitesse stage 2 for power, car will see the road course as well as the street.

I don't want a heavy effort pedal, but I also don't want to do this job twice. How are the manners of the KEP stage 1 plate? Pedal effort still fairly light?

Chime in please!

it appears that the clamp point is different but the diaprame is the same so the pedal feel is good from most accounts the sacrifice is the pressure plate has slightly less travel so it genrally wont take a full thickness cup disc of about 9.3mm..
so your options are get a second hand cup disc of about 8..8mm get a clutch net disc
try a new standard disc . .
or have one made ... there is realy no need for them to be expensive .

all the spec clutches are just upgraded linings and this is genrally the cost effective way .
if you are willing to spend a bit of time getting the cup disc to work with the KP pressure plate it will work well ..
you will need to machine your flywheel for less preload . or have shims cut to space your pressure plate out a tad.

Stock flywheel (no special machining), Spec 1 friction plate, KEP PP. I have never had any issues driving forwards. Sometimes it chatters in reverse, but who ever reverses. Pedal feel perfect, engagement point as stock.

No complaints

The KEP is going to be a bit stiffer then stock. I'm not sure how picky you are on this. The best thing to do is go for a stiffer PP (KEP 1) and then a more mild disc (go to clutch net for this). This combo will allow a friendly streetable shift, and it will allow you to slip the clutch. What you don't want is the on/off of a aggressive clutch disc. I really do like the factory lightened flywheel, good choice.

The stock feel is abnormally light. With the KEP I would rank it as same pedal effort as a normal car! Really, it's not bad at all.

I am using a similar setup, KEP stage 1, 930 disck and lightned stock. I like it very much.

Doh !!?! but there was a thread a cuple of weeks ago saying that a Kep plate wont open up enough to release a 930 cup disc
any tricks like putting a cap on the end of the slave rod ??

I believe that's with a lightweight aluminum flywheel.

I believe the main issue with KEP + 930 disc is when the thrust bearing is worn resulting in lots of axial crank play, or a Fidanza is used.

I'm now using the PP/disk combo from Southbend Clutch and am pretty happy with it so far. It feels virtually stock, but the PP has been reworked for more clamp and they use their proprietary "feramic" material on the disk. By default, they put their material on a standard 951 disk (the kind with the little damper spring that break) so I sent them a new cup disk and had them re-line it with their material. It's held 20psi on my 3 liter with no problems, and "feels" pretty much stock.

Tom, you say you're "Pretty" happy...any reason not to be 'Very' happy? Those Southbend products seem to enjoy a good reputation.

I am indeed 'very' happy with it, if not 'super' happy.
What's not to like -- holds all the power I've thrown at it, but feels like a factory car....

Would your set-up using the "feramic" lining be the equivalent of their stage 3 HD kit do you think?

I installed a KEP stage 1 a few weeks ago and pedal effort is slightly more than stock, but not significant by any means.

I had trouble getting the 930 disk to release due to its thickness. Everything checked out fine (axial crank play, fork wear, etc.). The KEP engineer I spoke with wasn't sure why the combo works for some but not others. Anyway, I put in a 951 cup disk and it works fine. I haven't driven the car much since then to gauge chatter and such.

Cup disc, KEP Stg 1 PP, Spec alum flywheel. Love it.

KEP I, 930 disk, lightened stock FW - pedal effort is just slightly stiffer than stock and most certainly streetable.
