The noise I've heard on YouTube videos does not sound like a vibration it's like a chattering no engine would transmit that sort of noise without being well and truly fucked.
It sounds like something is not releasing enough like the clutch plate etc .
I could live with he vibration but I could not sit in a car at the lights that chatters like the videos on YouTube.
Has anyone fitted a ttv kit using there sprung clutch plate and cover and flywheel.
