Nonamedude Posted March 4, 2020 Share Posted March 4, 2020 I had an Exedy Stage 1 clutch and Exedy Stock WRX single mass flywheel installed along with Group N Transmission and Engine mounts (kept stock Pitch mount). The deceleration noise is significant. You say had. Did you change something that decreased the noise? Link to comment Share on other sites More sharing options...
ashwinearl Posted March 4, 2020 Share Posted March 4, 2020 You say had. Did you change something that decreased the noise? Sorry 'have' . It was installed just recently. I am still getting used to it, but it doesn't really bother me, and even like that 'raw' sound. The problem though is the magnification of pre-existing dash rattles and the other rattles through the car. Link to comment Share on other sites More sharing options...

Yea the main rattles bothering me are the left radio bezel and the passenger door speaker grill. I'll get around to them all eventually Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Max Capacity Posted March 4, 2020 Share Posted March 4, 2020 Thinking about this more, I seem to recall I noticed the decal noise the first time shortly after I had the OEM DMFW removed back about 2007 and replaced with a LWFW Spec FW. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

chato Posted March 5, 2020 Share Posted March 5, 2020 (edited) think this is clutch noise, I have the same exact thing. first thought it was my trans getting ready to grenade, had a backup so swapped it, and had the exact same noise. did a 6mt swap with new clutch and its still there but quieter (went from LWFW to stock STI). do you have stiffer trans bushings and or shifter bushings? that plus the SM/LW flywheel seems to really amplify it.

xt2005bonbon Posted March 5, 2020 Author Share Posted March 5, 2020 I do have a groupN 'dogbone', and I believe groupN trans bushing. But interestingly, this exact set up was on the car before the swap and it did not exhibit much decel noise. Link to comment Share on other sites More sharing options...
Max Capacity Posted March 5, 2020 Share Posted March 5, 2020 May be one of us should call Spec Clutches and ask one of the sales reps, what's their "drivability" package do for the Spec 2+ clutch. I wonder if its something to do with issue ? Or just allow you to drive at a lower RPM in a higher gear ? 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

xt2005bonbon Posted March 5, 2020 Author Share Posted March 5, 2020 mmh. now that I think about it. There is one difference between before and after: the throwout bearing. Before, it was an OEM like bearing. Now, I am using a TSK3 kit. Not sure if it makes a difference at all though. Link to comment Share on other sites More sharing options...
Max Capacity Posted March 5, 2020 Share Posted March 5, 2020 I don't have the TSK3 kit and my wagon has been noisy for 12 years. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

xt2005bonbon Posted March 5, 2020 Author Share Posted March 5, 2020 Mine was good too. Put it just in case the TOB grenades one day. Link to comment Share on other sites More sharing options...
chato Posted March 5, 2020 Share Posted March 5, 2020 Bad TO bearings tend to make noise when the clutch is depressed in my experience Link to comment Share on other sites More sharing options...
chato Posted March 5, 2020 Share Posted March 5, 2020 FWIW, I think its the whiteline crossmember bushings that are really causing most of the NVH on my car. If you search exedy clutch noise, there's no shortage of links about it from other cars. Link to comment Share on other sites More sharing options...
