I did engine and tranny mount together, as recommended on my stage 2 T7 9-3. On a chilly morning, the vibration is significant until they warm up a bit. After that they are fairly smooth for poly mounts. The shifter feels immediately better. It even sounds better with a satisfying (but plasticky) click at gear change. Both powered and un-powered turn-in drastically improved which is a pleasant surprise. I need to avoid leaving the TCS on when people are watching. A spirited snatching of second gear causes a panic response from the TCS module resulting in some embarrassing noises from the stock diverter valve and glazed flywheel (not my fault) followed by a dead spot that lasts for about 50 feet before trying to boil the meats again.

More power to the ground at the moment of acceleration/ deceleration, no question. Also these are beautiful parts...so sad to hide them under your car. Finest mounts I've ever owned in a two decade car habit!
