Sorry I can't remember which, but it surprised me. I was messaging several sellers trying to get specs and many didn't know squat.

An important factor is knowing which of these require an specific FW, if price is important in the decision making.

ZERO clutches require a specific flywheel as they don't care. The only rule of thumb is if you are smart enough to want a lightweight one, you should match say Exedy to Exedy and not Exedy to ACT as no brand recommend missmatching brands. That may be marketing BS though.

The seller could have been uninformed and gave me incorrect information. The website (competition clutch) was also incomplete (as it still is) so legit information was pretty much impossible to find. I decided on another setup to stay reliable and streetable and it is sufficient for now. I likely will upgrade again once I've installed the "final" three parts before the tune, it just sucks not being able to see how different clutches perform without being able to experience them in person. There are practically zero people with a setup close enough distance wise and close enough to what my vehicle will be soon to be able to compare.

That statement is very difficult to for anyone to prove or disprove because there are too many variables, so its easy to make. I believe "matching" a flywheel to clutch is hit and miss mainly because of weight differences, because if they are machined to the same tolerances and measurements they should physically maintain all of the same dimensions as oem. Of course with so many sellers and so many brands its tough to get all of the pertinent details and some of us would rather be driving the car than having it sit in a garage for years deciding on the perfect setup. I use my car nearly every day so its tough getting enough FACTUAL vs opinionated information to make an "informed" decision in a timely manner. I'd rather be driving and enjoying my car than letting it rot away though so sometimes wasting a little more money is better than wasting a lot of time.

The clamping force ratings for the Sti branded clutch plates, in the SPT catalog, are the same as the ones form Exedy, at least for the 5 speed.
For the same clutch plate rating, Exedy shows the same clutch torque rating.

This applies for the 5 speeds. Then the 6 speeds have larger torque holding capacity, for the same clamping force by the plate.

The clutch torque that Exedy lists, is the torque needed to be applied to a disc (say on an engine dyno), to have it completely spin over, while engaged. It's an industry standard, I think.

I think that the flywheel torque listed, is the correct value, to be referenced.

Hi Guys,

I'm from NZ, so I'm not sure if my car is a bit different (import from jap i believe).
This site is my car:

http://www.carjam.co.nz/car/?plate=dlm447

its an 02 WRX (i believe STi, as it has a lot of STi things in it.).
Its Turbo Manual, 2L. 5 gears + Reverse (is that a 5 or 6 speed)?

I have found these two clutches and am wondering if they will work. They say they will work with the WRX, but nothing about the STi version.

http://www.rallysportdirect.com/Exed...acement-Clutch

and

http://www.rallysportdirect.com/Exed...acement-Clutch

I have searched the forums but it seems its all talking about the WRX, and not the STi.

I am trying to sources from the states as its a lot cheaper. $250 instead of $650 over here.

Any help is greatly appreciated.

Get the transmission ID of the sticker on the transmission. http://rallispec.com/tech.html This will tell you if its push or pull type, in case someone has swapped it for a different type.

ok ill see if i can get under it.

just seems odd that there is hardly any mention of an 02 WRX STi, so just wanting to make sure.

EDIT:
my chassis number starts GGB. Oakos.com/wrx/chassis_codes.htm states it's a "new age" wrx sti sports wagon, which isn't avaliable in the US.

This is getting too confusing :/

And to make it worse I do think the transmission has been swapped as my reverse light don't work. The electrician said because the plugs weren't connected as the end were different. Meaning a swap?

EDIT 2:

So this link shows my car as being 6 speed. but i know its only 5 speed. meaning they have changed this.
so its now impossible to tell what i need unless i open her up?

And to make it worse I do think the transmission has been swapped as my reverse light don't work. The electrician said because the plugs weren't connected as the end were different. Meaning a swap?

Incorrect sir. The Competition Clutches for the 06-14WRX/05-12 LGT all require the Competition Clutch LWFW be used with the clutch.

Competition Clutch manufactures their own pressure plates in house. They do not rework an Exedy. So, the bolt pattern on the pressure plate is not OEM. It will not mount to an OEM FW or any other brand aftermarket FW. Just as the LWFW will not work with any other brand pressure plate, only Competition Clutch.

The Competition Clutch kits are sold and packaged with the required LWFW.

This does not apply to 04-14 STI/07-09 SpecB 6MT or 02-05 WRX 5MT.
