5 Puk Or 9 Puk

[bugger]

Hi all,

I'm looking at Exedy Clutch...

but what's the difference between the 2 clutches???

5 puk or 9 puk is better?

I do not want any jerk when I down gear, that's one of the most important issue.

help is appreciated.

Cheers.

5 puk or 9 puk refers to how man pads there is on the clutch face.

If u dont want the jerk on downshift, blip the throttle in the downshift (when clutch is in and just b4 u put it into the next gear)

[bugger]

I know what you mean.

But does the 9 puk or 5 puk have this problem? must I really step on trottle before I downgear???

what's the difference in terms of 9 puk and 5 puk?

I know the number of plate, but in terms of jerking?? or easier driving??

[blind_elk]

The jerking on downshift is basically independent of pucks. It's all a matter of driving style. The blip is called "heel-toeing'. The reason you get the jerk is that the engine and gearbox are not spinning at the same speed for the gear you are selecting. Heel-toeing matches the engine speed to the gearbox (road) speed.

Oh,

so is all BUTTON clutches require a heel-toe to prevent jerking???

i'm looking at ceramic button clutches.

so, what's the difference between 5 puk and 9 puk?? apart from more plates.

[blind_elk]

All clutches (not just 5 / 9 button pucks) benefit from heel-toeing on downchanges.

I think the more buttons, the more of a pig it is to drive generally.

generally its the more buttons the more driveable it is,

3 puck is going to be far worse to drive then a 9 puck

as u can see, the more puk's the greater contact area on the flywheel and easier to drive it will be.

Thanks guys...

What's the difference between Cushion Button and just Button clutches???

sprung center. Notice neither of the clutch plates shanef has shown have the springs in the center.

what's the use of the sprung center?

is it easier to drive???

[shanef]

it cusions the initial bite a bit. also some say its easier on the drivetrain.

on the flip side, it takes away a bit of the feel u get.

feel???

can you define 'feel'??? LOL..

well, an idiot with clutches is like that.

[Simon-S14]

feel is best described as where in the peddle travel the clutch starts engaging and how suddenly.

With OEM clutches... they have no feel really... once you get a button you'll learn all about feel for the clutch

thats for sure..

I use an Exedy Hyper Carbon Twin plate.....kinda crazy if u drive it in heavy traffic.

Currently, I have a ceramic clutch in my car, but i can ride the clutch without stalling.

i heard that ceramic button clutches cannot ride the clutch right???

why is this so???

is there different kind of ceramic clutches???

[Simon-S14]

riding or prolonged slipping of the clutch will quickly kill a ceramic clutch, due to the nature of the materials they quickly heat up and cause damage to the surfaces.

Avoid slipping a ceramic/brass button clutch at all costs!

[bugger]

ok.

i guess i have a final question.

Out of the clutches below, which one is the easiest to drive??? and when I down gear, there will not have a shudder...

-5 puk ceramic button

-9 puk ceramic button

-cushion button

select one from the above. the main important point is that I do not want the car to shudder when down gear...

Cheers.

[Simon-S14]

Hear this

ALL CERAMIC/BRASS MATERIALS WILL SHUDDER ON DOWNSHIFT IF ENGINE REVS ARE NOT MATCHED!!

Its due to the nature of the materials used...doest matter how many pucks or whatever. if you do not rev match, then your pretty much slipping the clutch everytime you downchange.

But, as for most driveable.. a 9 puck cushioned button will be the most driveable

[kudos.motorsports]

Hong, going back a few posts a cushioned clutch has nothing to do with a sprug center rather a cushioning between each side of the clutch plates. A conventional button uses a single sheet of metal with puck either adhered or riveted to it. The Cushioned plates use two plates with a "spring" in-between. This "spring" takes the initial shock of the engagement rather then other driveline components such as gearboxes and diffs

Bacially if the vehicle is mainly a daily driver, and a puck clutch is your preference, I would strongly suggest using a cushioned item.

The sprung center is purely a sound/vibration dampener.
