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.

3 puk - http://clutchnet.com/photos/3button_solid02.jpg

5 puk - http://www.mpautoparts.co.nz/images/PukPanel.gif

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

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 :rofl:

thats for sure..

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

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. :thumbsup:

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

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 :laugh:

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.

If you need any further information or pricing on Genuine Exedy Clutch Kits drop me a line.

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
