The meets here in toronto have dwindled down due to cold weather... so no one else has heard or experienced my setup... That said, I have only had it for less then a month, so it's not like I have forgotten how the stock clutch felt.
There are no added vibrations in the cabin, like I said, there is a very limited audible feedback when at idle(my turbo blanket added that) and when the ac is on it is just a tinny bit louder. 1/4 volume(pretty low on the dynaudio) completely covers that up, but all be told, I find that it adds another character dimension to the car experience.
On the weekend I drove for 2 days a well running mk4 jetta TDI. and my wife mentioned that that my car is really refined and silent compared to that.
Again, no chatter or noise while the car is moving.
The car has a cool little extra sound attribute when leaving from a standstill, reminding you it is not a stock clutch. I like it.
And yes gear noises are present when decelerating, because racekar
As soon as I'll get to meet with some forum members who drive manual/southbend clutches, I'll bring it to their attention to make their own comments on this thread.
I know lots of folks are curious/ worried, just ding my part to help the community.
