Got one in mine as it came with it.

pros,

handle high HP

handle a shit load of abuse(high rpm launches)

last a long time still going after 5 years of use

well built and engineered

no slippage

con's

gearbox breaker (no spring dampers or give)

bitch in stop start traffic

I thought more torque loading etc that the clutch lets through (quad vs triple) would mean more stress on the gearbox (physics), unless it has damper springs etc to take up shockloading. Still punishing gearbox though.

OS GIKKEN STR twin sounds good.......

Yeah i thought the same thing, Kier wilson explained it to me and showed me the differance between the clutches. Somehow the quad plate puts less effort on the driveline than the triple. if indoubt feel free to give Willalls a call, they had the trpiples in both there GTR's and now run the quad's as they found them easier and more friendly to drive. YEs they are the OS distributers here in S.A and would try to make a slae off the quad rather than the triple but i got the quad at the same price.

Fair enough, main thing is as long as you are happy with it, go with it.

I'm happy with my os triple as it has lasted so long (daily driver, 380ish RWHP) and only one busted g box so far, 3rd gear.

well the number of plates has very little bearing on driveability at all.

two equal clutches. both puck type. both metallic friction material. both same pressure plate. both solid centre. one is a tripple, one is a quad. I can tell you now they will both be the same to drive.

things that affect driveability of a clutch:

force of pressure plate

type of friction material used

style of plate (full face, puck type etc)

sprung/dampened centre

saying a quad plate is easier to drive than a tripple is still a useless statement. there are hundreds of types of each clutch. if I had a sprung centre, full faced, 1000kg pressure plate tripple plate. and on your advice that a quad plate will be better went and bought one. and it was solid centre, puck style plate, 1600kg pressure plate which do you think would be easier to drive? and kinder on the gearbox?

exactly. :) my point is. saying quads are better than tripples for driveability is not acurate. of all the factors in clutch design it probably has the least impact on driveability. and yes I've driven plenty of singles, quite a few twins, a number of triples and a couple of quads. I had an OS tripple in my GTR for over a year, and an OS twin in it for about a year.

so you guys wouldn't recommend a triple plate for daily driving? What power will a streetable twin plate hold up?

I converted my solid centre HKS twin plate to a sprung centre. Absolutely transformed the car (was a bitch to drive previously in stop start traffic) and seems to be surviving 400 rwkw abuse OK.

yep, massive difference between solid/sprung centre clutches.

and ookami, like i said, it depends on the type of tripple we are talking about.

if you are talking OS solid centre, puck style, tripple then no, it's no good for daily driving. if you are talking full face, sprung centre tripple, with a not too extreme clamp force then yes, it should be fine for street use.

Just get Jim to make you a clutch if your worried.

Tough as nails, great for street driving

best advice anyone could give you....

i daily drive my GTR, jim berry built mine.. it is a single plate button with a carbonics plate.. bites HARD.

and considering he built it cheaper than what a stock replacement costs... can't go wrong

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
