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.
Currently I have noises(or chatter) during deceleration(or downshift) and I hate it. Everytime I hear the noise, my heart stops a bit.
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.
