Product Information

Engine Mount HD RS Style Uni-Ball Centre.

Experience uncompromising drivetrain control with the HD RS-Style Engine Mount featuring a Uni-Ball Centre — the ultimate upgrade for high-performance Porsche 964 and 993 models.
Engineered for motorsport precision, this mount combines the robust RS-style housing with a spherical uni-ball bearing core, replacing the standard rubber insert. The result is near-zero flex or deflection under engine torque, ensuring sharper throttle response, improved gearshift accuracy, and stable engine alignment even under extreme load.

What This Product Does:

In a uniball (spherical bearing) design, the elastic rubber center is replaced (or augmented) with a metal bearing that allows rotation and articulation but eliminates flex / deflection.
This gives a much more direct mechanical interface—engine motion under load is significantly reduced compared to rubber alone.
Because the spherical joint has very low compliance, the mount becomes much more rigid in the direction of torque / twist (longitudinal / rotational direction) while still permitting the required articulation in other axes.
This variant is often preferred for track, clubsport, or dedicated performance cars where precision and rigidity matter more than comfort.

Symptoms Of Worn Or Failing Engine Mounts:

Excessive Engine Movement - When accelerating, decelerating, or cornering, you may notice the engine rocking or shifting more than normal.
Clunking or Knocking Noises - A distinct thud, clunk, or metal-on-metal noise when shifting gears or during abrupt acceleration/deceleration indicates the mounts are no longer isolating movement properly.
Vibration in the Cabin or Steering Wheel - As the mount deteriorates, it loses its ability to absorb vibration from the engine.
Poor Gearshift Precision - Engine movement causes slight misalignment in the drivetrain, which can result in imprecise or “notchy” gear changes.
Unstable Handling or Driveline Feel - Excessive engine movement shifts the vehicle’s center of gravity and can create a “loose” or unsettled feeling during hard cornering or braking.
Visible Wear or Fluid Leaks - The original Porsche mounts are hydraulic on many 964/993 models; when they leak fluid or collapse, engine support is compromised.
Rattling or Exhaust Misalignment - Worn mounts allow the engine to sit lower or twist, which can cause contact between the exhaust system and underbody components, leading to rattling or vibration noises.

Why This Upgrade Version Matters:

Maximum Rigidity / Minimal Deflection — virtually no unwanted movement, giving optimal drivetrain alignment and responsiveness.
Sharper Response & Consistency — throttle, shifts, and engine behavior are more direct because the engine is “locked down.”
Better Repeatability — especially in motorsport, lap after lap the behavior remains consistent.
High Load Handling — in high torque / high cornering environments, the mount retains its shape under stress.
Precision Feel — the driver senses a closer mechanical connection, improving control feedback.
