go Have a 02wrx wagon with 120 don't know prevous owner changed clutch but i do have clutch shutter would that mean its still the original?
My other question is if i replace it with stock oem will that take away the shutter?

 

My guess is it's the second. Mine first only lasted 65k.

 

I'm still on the factory clutch at 227K Miles and counting.

Chances are that yes, a new clutch would probably help resolve the issue when coupled with a new flywheel (or at least a resurfaced one, but I personally prefer just getting brand new stuff for wear & tear items).

 

I'm at 98k fully modded stock clutch.

 

I'm on stock clutch at 113k with 300+ awtq for 20k miles so far.

 

It could be that the previous owner had mods and put in a heavier duty clutch. Most "stage 1" clutches will shudder some, I know for a fact if I don't let it out just right, my ACT HDSS does the shudder.

 

It could easily be original clutch.. Normally when a clutch starts to wear out is starts slipping. Shuddering could mean mechanical failure somewhere in the clutch pressure plates. If you decide to replace it make sure you get a genuine normal Subaru wrx clutch.. Don't get a heavy duty racing clutch or what ever or we will see you back here in a few weeks asking about gear box replacement.. With the power of a rex and AWD the cheapest weak link in case something breaks should be the clutch...A new gearbox will cost a LOT more...and like someone else said.. get your fly wheel machined. Gives nice smooth grip and makes it lighter at the same time.. ;0) ...

 

My stock 02 clutch had shudder, but mostly when cold, rarely when warmed up.

I replaced it at 145k. Very possible it's original clutch unless the original owner was driving hard on it all the time.

 

This part should be added to the Bible. Forever and ever amen.

 

i loved my act hd street clutch. My STi had only like 280 awhp, but always felt good on consistant autox launches

 

Replaced My OEM on my Stage 2 2005 STI at 95K with ACT HD & Streetlite Fly wheel. Shudders a bit, but very Solid Clutch- Very Happy with it.
