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.
Delrin (Acetal) motor mounts, transmission mounts, and bushings are each machined from a solid blocks, and have either Stainless Steel or Aluminum bushings fit into the mounts to act as a point of contact for the connecting bolts when required. Delrin is an extremely strong and stiff plastic. It is commonly used in place of metal in applications where metal can not be used (magnetic, corrosion, or conducting / insulating reasons). These are much stiffer than polyurethane mounts, and it will not give or wear out. Delrin mounts should never need to be replaced, unlike the stock units which are usually considered a wear item.
Delrin mounts minimize the jumping or twisting of the motor under the hood. This movement is caused by the rotating mass of the crankshaft and transmission components. With stock mounts, the engine will twist itself in the engine bay when the throttle is opened, or during high-speed shifts. Over time, this force will destroy the stock rubber mounts. When this happens, the rubber may split or rip, allowing the engine to potentially move inches back and forth. This can destroy CV joints, other mounts, and create wheel-hop.
With our mounts, shifts will be much crisper. While pressing the gas pedal, a vehicle is much more responsive; as the motor does not lose as much torque twisting into the mounts.
At a price usually less than that of inferior stock mounts, these are not only a great performance item, but a bargain for each application.
