My stocker has finally givien up the ghost. Not that I'm totally surprised about it or anything, but I just don't know what to get now.

I'm soliciting suggestions. IF you have one, please include a vendor where said clutch can be pruchased.

I'm at about 400hp crank on the bottle, 340 off.

TIA for any help.

Edit: Also, would it be a good idea to replace the TOB now? Or can I wait since I only have 27k miles on the car.

Definitely replace the TOB. It's a cheap part, but the consequence if you don't change the TOB with the clutch, is if it goes....the labor involved is basically a clutch replacement.

Whatever clutch set you get, make sure it's a sprung design.

Try looking at brands like Centerforce, ACT, Clutch Masters, etc.

That's the thing. The TOB for the WRX is NOT a cheap part.

Good point about sprung hub. I guess it's also worth noting that I want a full face disk since this is a street car.

let me rephrase....

In the event of a TOB failure after a new clutch install, the cost to replace the TOB far exceeds the initial cost of installing a new TOB the first time.

i agree, the cost of the part plus cost of labor is less that cost of the labor, part, and labor again.

have you considered Exedy for the clutch?

I have 2 quick question:
1. What is TOB?
2. How do you know when your clutch is dead? I had a manual for a while, but got rid of it before it needed a new clutch and my other car was automatic.

1) TOB = throw-out bearing. Here is a definition:

2) You will feel it start to slip. You change gears but the clutch lags in actually engaging it.

Try an Exedy clutch, it's organic holds good power and smooth. Feels like stock, and Exedy made your factory clutch as well. Lastly, they include the release bearing for free as many of you know is expensive. They also offer a chrome-moly flywheel (which is probably the same as the Sti unit since Exedy makes the flywheels for many companies). If you're not using an ATS carbon clutch, the Exedy is what I recommend.

SHIPPED.. not slipped. ;)

The clutch I ordered is (surprise) an Exedy. It's not an actual Subaru part, but is the same clutch as stock without the markup.

Aussie,

Don't worry - you're not the only one seeing things. I read it the same way twice after I hit the "quote" button. Had to back up out of the reply really quickly. :D

What about these "STi" clutches for the 5 speed?

RST-1000kit STi Fast Road Clutch Kit
Complete clutch kit includes: 230mm STi organic clutch disc, 850kgf STi RA pressure plate, release bearing, pilot bearing, and clutch alignment tool. Provides more positive clutch engagement and higher torque capacity for lightly tuned engines. Segmented kevlar clutch disc withstands higher temperatures then stock while maintaining smooth clutch engagement.

RST-1002kit STi Performance Clutch Kit
Complete clutch kit includes: 230mm STi organic clutch disc, 1050kgf STi Sport pressure plate, release bearing, pilot bearing, and clutch alignment tool. Higher spec. version of the RST-1000kit with a high clamping-force pressure plate to handle the torque output of moderately tuned engines. Kevlar clutch disc withstands higher temperatures then stock while maintaining smooth clutch engagement.

RST-1001kit STi Competition Clutch Kit
Complete clutch kit includes: 230mm STi 3-paddle sprung center ceramic clutch disc, 1050kgf STi Sport pressure plate, release bearing, pilot bearing, and clutch alignment tool.

RST-1007 STi Twin Plate Clutch Kit
Multiplate clutch raises torque capacity over stock without significantly increasing pedal effort or clutch shudder. Smooth clutch takeup minimizes destructive driveline shock.

Impreza WRX w/ 5MT Gearbox -- $2005

Do you think these are Exedy also?

man, I would be really leary of putting a clutch with an unsprung hub in the wrx. They cause a lot of shock to the trans and driveline..granted the materials used on the disk can help if they dont grab 100% on engagement ie dont use a metal puck disk...

will an STI 6speed clutch fit a wrx 5speed????
