Cool, I already have Mazda/Exedy bearings.

 

Beginning to test prototypes of our new line of 949 Racing brand performance clutches. Much burlier, higher capacity than the F1 line and about 2-3x the price. Started from scratch designing these so they'll be exactly what I want in an affordable race clutch. Will start a new thread with details when we get further along in development. Looking to have stuff ready to ship around the first of the year. Until then, the F1 is a good value for a modest increase in capacity over the stock clutch.

 

I have put about 8k miles on a stage 2 F1 clutch, and honestly, to me, it feels exactly the same as stock. I also got the lightweight flywheel which is pretty cool, but the clutch feels pretty puss. And maybe it was just me, but it seems like it has taken forever for it to break in fully.

If I had to get another F1, I'd definitely go for the stage 3.

 

Sounds like I'm getting the 6-puck.

Did that guy who was saying he was putting in the F-1 stage 3 ever did?

Emilio, how much do you think the 1.6 stage-3 will hold?

 

nubins is holding almost 300 wtp mine started slipping around 250 still for the $ it isnt bad at all

 

I’ve had no complaints whatsoever from my ACT Extreme 6 puck in the 1.6 L version with a 7 lb Fidanza flywheel.

Launches just fine and is holding 320 ft-lbs of RW torque.

I am skeptical that the sprung hub helps the transmission though. With this much torque the springs bottom out and when they do I think the movement makes it so it can behave more like a slide hammer than a suspension.

I still want a twin however.

I won't be any where near that.

so is the general consensus that 6 puck discs in general don't need to be broken in as long as a full face disk?

(If I had to guess, it'd be because of the reduced amount of actual friction material?)

7lbs, Bbundy? Is that a two piece aluminum - how fast do revs drop?

 

The actual weight of the off the shelf 1.6l Fidanza flyweel is 7.4 lbs. It is aluminum with a steel friction surface. I have zero issues with being able to daily drive it. Most people stall my car a couple times when they first try to drive it but quickly get the feel for it. I can’t remember exactly but I think the whole clutch and flywheel assembly was like 18 lbs or about the same weight as the stock 1.8 flywheel by itself. It is still heavier with more MOI than a 949 racing twin though. I am definitely not afraid of going lighter.

FWIW I also tried a Spec Stage 3+. It juddered like crazy made it hard to drive without looking like an idiot and it wouldn’t hold my torque.

I put the F-1 6 puck in yesterday. Dropping the tranny was a major PITA. Those of you with BEGI-S kits take note: the down pipe cannot be removed without the turbo being removed, which cannot be removed without the manifold being removed after its all in the car.

After it was in (and swearing subsided), the clutch pedal fealt nearly stock, real easy. And even brand new, if you slip it just over 2,000 - it was as smooth as glass. My friend, who's accustomed to 6-pucked FC's had to make the first drive and after that, it was clear what the clutch's trick was. This is my first 6-puck and even I think it's easy.

It holds out of the box (but I haven't dropped it yet, going to give it some time).

Long term quality remains to be determined, but thus far - this clutch appears to be budget win.

 

Emilio, did you stop selling the F1 clutches?

Luis, how is your clutch doing/
