FX400 with stock flywheel
 

I recently installed CF driveshaft, lightweight crank pulley, perrin 3" exhaust, perrin rear shift bushing, perrin transmission mount, and FX400 with lightweight flywheel. This was my first mod in my life, and I was very upbeat about it.:happyanim:

Currently I have noises(or chatter) during deceleration(or downshift) and I hate it. Everytime I hear the noise, my heart stops a bit.:brokenheart: Everyone which including manufacturer says it is normal for performance clutch. I did not want any noise from my FRS which I am planning to keep forever(or least 15 years)

I posted FX400 for sale but I decided to try something else to see if this fix will remove the noise.

update on 0827 Nov 14, 2014: I switched back to stock crank pulley, and chattering is reduced about 10~20%. Also drivability of my FRS is increased. I am thinking about FX400+stock flywheel this weekend to see improvement on chattering. Thanks to Crosscharge!

another bump

Mine is stock so I cant help you too much.

This thread mentions that lightweight crank pulley + lw flywheel can wear bearings out prematurely.

FX400 does not fit into stock FW. The CM LW FW is required.
