5,5" you can make flywheel/clutch lighter that 7,25" setup. But whit 5,5" its so hard to start move. also if you are going to drift those clutch, its so ON/OFF you will kill you trannie whit dorifuto clutch kicking. If you will drift look clutch where is springs.

yeah a sprung hub clutch is key to minimizing driveline shock...but drifting is a competition to see who can do the most harm to the motor vehicle anyway...Right???


Really the only reason you are looking at smaller than stock clutches is to reduce mass in the driveline, if you're gonna do it DO IT get the smallest you can afford that has a sprung hub unless you have a dogmission or severly stout tranny, basically just pick your failure point tranny or clutch

clutches are cheap.. stick with a "regular" clutch to save the more $$ tranny.

Even a dog box will die a quick death with what drifters do to them. in many ways they're more fragile than a synchro tranny, so you gotta be careful.

A 5.5in clutch will suck for drifting, if you plan on clutch kicking at all.

With a rotating assembly that small and light, there's not enough inertia to shock the rear tires out of traction when you clutch kick, aka it will just do nothing.

Many drifters that have gone with lightened flywheels and all that all went back to a heavier flywheel and clutch setup because of that reason.

Exedy Hyper single. By the time you spend money on a good clutch and flywheel combo your in the same price range.

thaks for this info i think iwill go with 7.25 and im not sure what matrial i should use any input on this too i was thinking carbon w/ semi matalic

[Matt93SE]

So everyone here tells you NOT to run a small clutch if you want to drift, and you're asking us which small clutch to use?

[Markku Kiviniemi]

I will use 5,5" and i dont think its weight issue, its just so hard for tranmission. Becose its so solid, ON or OFF. So trannie will be fuse and stock box is not that good. Team experience over 10 damaged trannies tell that for us. I have totally difrent kine of box, im now worried at rear diff and axsels. Carbon disc is one bad choice for drifting when doing cluct kick, those will blow. Really good for track use.

Why have you decided that 7.25" is better for your application than a stock-size setup?

Sometimes, simpler is better. Trick stuff can be cool, but there are often problems which are overlooked or unforeseen because one falls into the "trick trap" and only thinks about the advantages of a setup.

Not to mention replacement parts will be expensive, because it's not as common as stock.

Honestly, the Exedy Hyper Single is a great clutch. Many people who has drifted or road raced their cars with them have nothing but good things to say about them.

It's a lighter clutch assembly than stock, but still has the inertia for you to break the tires loose when you clutch kick, but will still allow the car to rev up quicker than the stock clutch, just not like a 7.25" or 5.5" clutch would.

Exedy, Os giken, ORC, HKS etc etc all of those are really good and they make clucht/flywheels set what is much nicer for trannie. Those are really light weight. Flywheels is pure porn, molocrome cnc parts.

My view for weight/size is not reason for trannie break down. Less weight quiker respons, but revs drop much waster when you lift up. wich is not good for drifting, but make gear brake easyer. I have many friend who is using 7,25 or 5,5 clucht and all of them had problem whit nissan oem trannie, then they have chainge tremek T56 or TK600. No more trannie problem, but now rear diff pinjon ring or axles or diff axles joint is kiving up. All who have this problem is driving drifting and more of this they break down what better tyres they are using.

i also plan to do a lil time attack with my car as well and talked to a few clutch companies as well and they say for what they have seen 7.25 would allow me to be to do both 8in is what they advise but they said 7.25 would work too so i chose the smaller i havenet made a full choise yet im still shoping around
