In Oct. last year I had the torque link and gearbox end OEM motor mounts replaced with VibraTechnics, and since then, I notice more vibration from the front end under WOT, especially in 4th or 5th gear. At cruising speed (even 100+), the car feels solid & steady, I just feel the shake when I pin the fun pedal. I had the passenger side upper motor mount changed to VT 2 or 3 years ago when the RMW shorty header was installed, and no side-effects from that. I'm kinda surprised to feel more vibration from the additional two VT mounts. (I thought the engine and car would be more stable/solid with better mounts.) Are these vibrations a bad thing, something to be worried about long-term?
