benkei Posted February 10, 2011 Share Posted February 10, 2011 My Supe is equiped with a OS Giken Triple Plate Clutch. I feel this clutch is a little over kill in my almost BPU'd Supra so I've been reading up on them to find out what it is I'm dealing with! Now it's backwards from a standard clutch as they can either be 'push' or 'pull' clutches... So what is mine? I've heard nothing but good things and possitive feedback about this clutch. It would be perfect for a big single or a big powered Supra. I don't think I'll ever be running enough power to warrant such a hardcore piece of equipment! It also has a lightened flywheel too! From my experience of driving with it, I can say that it's a lot easier to use than I was expecting. When booting it I feel confident that the clutch is handling the power with ease, and when changing gear it's smooth, after a little practice! But the pedal is heavy! And it's quite noisey too, sounds like it needs a new clutch or something! start-stop diving is awkward, and that's mainly what I use the car for! After reading up on other people's experiences, it seems that changing back to an OEM clutch can be a pain! And an expensive one, which makes me think that I'm best to just stick with it. But I don't know if it's just not suitable to my style of driving and for a daily runner with around 400bhp! Also, does this kind of clutch affect MPG? I'm finding that the Supe is a LOT thirstier than I was expecting, and I'm trying to see what kind of things are contributing to that, see if I can alter or change things to improve it! Can I get some feedback from you guys Quote Link to comment Share on other sites More sharing options...
Jurgen-Jm-Imports Posted February 10, 2011 Share Posted February 10, 2011 you will need stock flywheel, clutch and bearing..(possibly might need fork too the slave cylinder is like stock on yours.. but OS giken is expensive so most likey you will come out with £ if you swapped over.. i have a customer that has stock clutch and is going to go single in summer so maybe (you can do swap with him ?)

Nic Posted February 10, 2011 Share Posted February 10, 2011 Definitely overkill, I'd sell the clutch assembly and go back to a stock flywheel with up-rated clutch cover and disc. Quote Link to comment Share on other sites More sharing options...
benkei Posted February 10, 2011 Author Share Posted February 10, 2011 I've been looking at maybe getting an uprated clutch, so that it can easily cope with BPU and last a while. I read OEM can cope with upto 500bhp? There are so many different clutches! Thanks Jurgen, that could well be a viable option! Quote Link to comment Share on other sites More sharing options...
Nic Posted February 10, 2011 Share Posted February 10, 2011 An OEM clutch will cope with general BPU driving. If you want something with a little more bite CW supplies uprated OEM clutch covers and discs. Quote Link to comment Share on other sites More sharing options...
benkei Posted February 10, 2011 Author Share Posted February 10, 2011 I may get an OEM clutch and see how that goes, then when that needs replacing get something a little tougher! May hit CW up and see what he suggests. Thanks Nic Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted February 11, 2011 Share Posted February 11, 2011 The Giken uses an expensive movement reversal kit to turn the stock pull clutch operation to a push type bearing. In the swap quite a few original bits will have been removed and probably lost or binned. The cost to buy the missing bits new, APART from a stock flywheel and whatever clutch you buy is about £220. I do an uprated stock clutch to use with the stock flywheel, which your car WILL NOT have as the Giken uses it's own one piece lightweight flywheel. I supply overhaul kits fand spare parts for all Giken clutches and LSD's, (try getting that sort of stuff for other makes...), but really a triple plat is overkill, and a needless expense in terms of maintenance. Being a cerrametallic clutch it's really for competition usage, and will wear rapidly on the road. My uprated clutches: I use the stock, brand new driven plate, as it is correctly balanced, doesn't judder and will hold all but mega torque highly modded engines or cars used for drag racing. I modify a stock brand new cover to give more clamping force. The reason I tooled up to do these is some of the aftermarket US clutches I have fitted SEEM to be built from used cover assemblies with reground friction surfaces, and a stronger spring. I have had hellish trouble getting these to fully release, because due to this seemingly thinner cast iron friction face, the geometry of the clutch goes to pot, and being a pull type clutch (the hydraulics pull the bearing away from the engine, rather than the more normal push type) it is a lot harder to effect a cure. For 455 pounds plus VAT , you get a brand new driven plate, a brand new modded cover, and a brand new release bearing. I would rather fit myself so any complaints are down to me, I see a lot of clutches damaged by people without the right gear (a ramp and transmission jack, plus correct circlip tools and fitment) or clutches fitted to patently *uggered flywheels. I will do a supply only if you feel competent to tackle the job or are using a bona fide garage to fit the clutch Toyota use a dual mass flywheel (the flywheel is in 2 parts, an inner and outer assembly, damped in the middle) which is now showing signs of wear causing a lot of rattle when idling or on very light throttle openings. For God knows what reason they are charging about £270 + VAT for a new one, they look more like they should be over 500 to me, but don't say anything :-) The very similar LUK dual mass flywheel on Maseratis is nearly £1000 + VAT.... So if the flywheels old enough or abused enough to be scored it should be replaced. Fitting by myself will cost £175 + VAT. Reply privately if interested please.
