After separating a motor mount again I knew I needed something stronger than stock motor mounts. I didn't want the harshness of solid motor mounts on a street driven car the vibration from the engine will eventuality take its toll on other parts. This modification not only keeps the motor mounts in one piece, it will also put more torque to the driveshaft by eliminating the flex in the OEM mount that is lifting the engine when it is rev. It will make a more responsive drivetrain that will responds crisper to throttle response. You also gain less wheel hop, not to mention less chances of the headers hitting the shock towers due to the engine twisting. With this modification I can now have almost the smoothness of rubber mounts and the strength of solid. I can feel a very slight vibration with the mounts being pinned, but it is not enough to be concern it is something that was expected.
New Motor Mounts
__________________________________________________
Step #1
Drill 2- 25/64" holes in each mount.
__________________________________________________
Step #2
Counter sink the holes.
__________________________________________________
Step #3
Use 3/8"x 1 3/4" Stainless
Flat Head Cap Bolts.
__________________________________________________
Step #4
Using Loctite, tighten nut until the bolt
starts to spin, plus an extra 1/4 to 1/2 turn.
__________________________________________________
Step #5
Grind the bolt head flush with the mount,
then paint mount to deter rust.
Now you have a motor mount that is solid without the vibration.
