Engine Mount HD RS Style, 75A Shore Rating. Porsche 964 / 993  ❭  96437504381

Upgrade your Porsche’s powertrain stability with the HD RS Style Engine Mounts — precision-engineered replacements inspired by the legendary 964 and 993.
These high-performance mounts use 75A Shore durometer rubber, offering a significant increase in stiffness over standard or hydraulic mounts.
The result reduced drivetrain movement, crisper throttle and shift response, and more consistent handling under load.

• Excess engine movement or shift under acceleration or deceleration
  
• Clunks, knocks, or bangs when shifting or when the engine “settles”
  
• Increased vibration, especially at idle or low RPM in the cabin
  
• Misalignment of driveline (axles, driveshaft, transmission) under load
• Premature wear on exhaust, wiring, hoses — anything connected to the engine that gets stressed when it moves

• Sharper Throttle & Shift Response - Stiffer rubber minimizes drivetrain lag and flex.
• Reduced Engine Twist - Keeps drivetrain geometry stable under load.
• Improved Handling Balance - Less movement means more predictable chassis behavior.
• Enhanced Durability - 75A compound resists collapse and fatigue over time.
• Track-Tested Feedback - Ideal for RS conversions, spirited driving, or track use.
