These bushings defintly do there job. Shifting is smoother and bucking inbetween shifts and when flooring it have became less noticible. The engine feels connected to the frame, it move MUCH less now. Down side is the NVH inside the cabin. Noise is increased while getting into first gear, around 1100 RPM, after that its smooth and the noise is gone. Auto transmissions will vibrate more at a stop then manual cars. Also when the AC is on you can notice more noise at a stop. Overall i like the product and the noise is worth the performance to me.
