Nemo's Stiff Motor Mount
The modified front motor mount that Nemo produces should, in my opinion, be factory stock on all ACR's. When people say it reduces wheelhop, they really mean that it eliminates it. The urethane core that replaces the softer rubber keeps the motor from rocking as torque is applied. The only way I've been able to attach any numbers to the improvement that mean anything is run the mount in C-Street Prepared at the local autocross and see if anyone notices. After only two runs, people are asking about the launches, wondering why everyone elses Neon is hopping the wheels at the start and while exiting corners. Within minutes I've been 'protested' for cheating. To put the advantage into perspective, many people loosely follow the rules at a local level and are allowed to compete anyway. Camshafts, head work, and many other rule-bending modifications are ignored because they don't make that big a difference. Every Neon owner there, even those who went to Nationals this year, was interested in the mount.
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. I don't find the vibration objectionable, but I'm willing to accept a little vibration if it means a better performing vehicle.
Installation is simple, a 15mm socket, a six inch extension,
and a rachet is all that is needed. No jack 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 mound, capturing the motor. Note that the nut is welded to the mount, it doesn't come off...
When installing a mount, the bolt that passes through the mount and the bracket off the motor (the long bolt) must be started first. Then install the two nuts and the remaining bolt.
Average time for installation is 10 minutes, very little mechanical aptitude is required.
