On the street our new mounts have had no real impact: engine or transmission noise is no better or worse than it was with our original mounts. Perfect! When autocrossing we noticed that it was easier to spin the tires when launching: this indicates more of the Cappuccino’s torque is being transmitted to the tires and not into deforming rubber mounts. This is exactly what we want! No increase in noise or vibration but better power transfer. We highly recommend these mounting kits as they are well priced, improve the performance of the Cappuccino, but don’t negatively impact its street manners.
