These upgraded front motor mounts are for various Porsche models.
The stock mount is prone to failure, and has been known to fail at less than 30,000 miles. It is hollow and not very strong. The photo of a mount below was taken out of a stock Boxster S and has been completely ripped in half. The movement was very noticeable from inside the vehicle.
Our mounts make the engine sound smoother and shifts are much crisper than stock. With the 6061 Aluminum / 60A Durameter Polyurethane mount, there does not seem to be any added vibration on an otherwise stock car, but the car will feel much more stable and stiff in the back. Pressing the gas pedal, the car is much more responsive, as the motor does not lose as much torque into the mounts.
The solid Delrin mount is for those who need or want even less movement and do not mind added vibration (perfect for a track car).
Either mount is installed just as the stock mount. Installation takes about 90 minutes, with floor jacks, a socket set, and a press to remove the old mount. The mount does not include the mounting bracket, only the insert replacement.
For the street mount, fit the polyurethane sleeve into the bracket first, then fit the Aluminum center into the polyurethane sleeve.
Stock mounts from Porsche will not survive long, especially with "spirited" driving, but either of these mount options should last the life of the vehicle.
Standard shipping charges will apply to the rest of the world.
