Aftermarket polyurethane motor mounts greatly if not eliminate wheel hop entirely. The urethane core that replaces the softer rubber keeps the motor from rocking as torque is applied. This sends the energy that would otherwise be wasted rocking the motor, to the wheels instead.
In this case a Nemo's stiff mount was used. It was tested at C-Street at the local autocross. After two runs a considerable difference was noticed when compared to other Neons with factory mounts which were experiencing wheel hop at the start and while exiting corners. At Watkins Glen, the mount seemed to help turn-in and the car felt more predictable on the edge. Gone was the 'wind-up' of the motor and driveline during downshifting at high speeds. Overall, the mount has few shortcomings.
Increased vibration is an issue with some people. The harder material transmits motor vibration as well as it limits it's movement. The vibration can be felt in the steering wheel and seat, and if any piece of trim is prone to rattle, it will. However the compromise is worth the increase in performance.
Required tools for installation
- 15mm socket.
- Six inch extension.
- Rachet
Procedure
Average time for installation is 10 minutes, very little mechanical aptitude is required.
- Remove the two nuts and one bolt that secure the mount to the frame of the car.
- Then remove the bolt that passes through the center of the mount, holding the motor. The nut is permanently welded to the mount.
- When installing the mount, the bolt that passes through the mount and the bracket off the motor (the long bolt) must be started first.
- Install the two nuts and the remaining bolt.
