Advice on Clutches for 05 Wrx

milocas · 02-12-2013, 12:38 PM

Alright I've done research on clutches and what not.. But my current clutch has about 60k on it and want to upgrade it or at-least have one when it does. There's no symptoms of it slipping, Just want to be ready. It currently has a exedy clutch and stock flywheel. I've search on the pros and cons of a light flywheel, but in reality, i rather not deal with noises and retain my stock flywheel and just resurface it. Now, Im currently modded with 16g, sti pinks, TBE, intake, Headers pushing about i wonna say 300 to the wheels, Give or take 50. I daily drive this car, street race here and there, NO Auto-x! But the clamp force for me wont really matter as i can take the beating. Im looking for a clutch that'll last awhile and hold my power.
Currently looking at ACT clutch, Number ACT SB3-XTSS. Is this clutch going to provide me what i am looking for? Thanks.

Anybody?

Torque is low enough on the 2.0L that you don't need much. I ran a stock clutch with an 18g @ 20psi on E85 for a long time, but don't street race or do any real straight line power shifting at all. It was definitely putting out more power than any car with pinks can.

With the 5MT as sensitive to shock loads as it is, you want to use a stock clutch as long as you can. pinks on pump gas isn't going to push enough to kill a stock clutch quick. Replacing clutches > replacing transmissions. Stock is best if it works for you... and it should. As a bonus, the Exedy branded version of the stock clutch (KSB03) is <$200.

OEM Clutch

Any disadvantages to using a OEM grade clutch rather than a upgraded one?

Inability to hold high torque load without slipping.

At a price of more stress on your gears.

Stick with OEM or stage 1

OEM will hold anything you're going to do with STi pinks.

An upgraded clutch will grip better, and slip less when you are shifting quick... but that will also shock your transmission more. I personally know someone who killed their 04 tranny with a 16g on pump gas less than a month after he upgraded his clutch. There's a reason people are recommending you stay with OEM. It may wear out sooner than a grippier clutch, but clutches are a lot cheaper to replace than transmissions.

Just note of caution, I recommend using the OEM Subaru clutch - not the "OEM" Exedy clutch. The Exedy can cause transmission noise on decel that depending on your personality may be OK or drive you crazy. I'm the latter - I deal with it but wish I spent the extra money on the Subaru part.
