So with everyone that has smfw. Do you guys also have any rattle/resonance/chatter type noise when accel on first or 2nd gear under 3500rpm or so?
The reason i ask is, i just installed my smfw with poly trans mount, now it sounds like a stripped race car inside with all the noises. Most noticeable is when accel in 1st gear lower rpm.

It's your trans mounts. Anytime I did poly, even with a stock dual mass, all the gear noise came right into the cabin.

Thx for the reply. The transmission shift so positive now. Just click right into gear. Maybe i will see if i can get use tonthe noise. If not i might have to swap back to stock or m3 ones.

Yeah I usually recommend m3 mounts for my customers and 335is engine mounts. I had Ireland Engineering trans mounts in my e30 and it sounded like a WRC rally car
