What This Product Does:
- This is a high-density (HD) rubber engine mount in the RS / sport style, intended as an upgraded or stronger replacement to the standard mounts offered on Porsche 964 / 993 models.
- The “65A Shore rating” refers to the hardness (stiffness) of the rubber material. A Shore A of 65 gives a balance: firmer than the softest mounts, but not excessively rigid, aiming to deliver improved engine control without too much harshness.
- It is often used as a pair (one on each side of the engine) to replace worn or softer factory mounts.
- The RS style mount replaces or upgrades from the factory hydraulic or softer mounts.
- In practice, what it does: it helps secure the engine more rigidly to the chassis, reducing unwanted engine movement (twist, yaw, vibration) under load (acceleration, cornering, braking). It helps maintain drivetrain geometry, gives crisper throttle response, and improves shift feel.
- Excessive Engine Movement / “Engine Rocking” - The engine may shift or rock under throttle or when revving, particularly during hard acceleration, deceleration, or rapid load change.
- Clunks or Thuds / Transmission “Bump” During Engagement - When shifting gears, especially from neutral into drive or reverse, or when applying throttle from idle, the drivetrain may “bump” or thud due to slack from the worn mount.
- Misalignment / Drivetrain Strain - Because mounts help maintain alignment between engine, gearbox, and driveshafts, a failing mount can cause misalignment, leading to extra stress on coupling joints, CVs, or mount brackets.
- Increased Vibration or Harshness - You may feel more vibration through the cabin, floor, or pedals, especially under load.
- Noise - Metallic rattles or clunks if the engine is loose enough to hit against brackets or the chassis.
- Rubber Deterioration / Visible Damage - Cracks, splits, or separation in the rubber portion of the mount.
- Upgrading to the RS-Style Engine Mounts (65A Shore Rating) transforms how your Porsche feels on the road. Standard factory mounts are designed for comfort, but over time they soften and allow excessive engine movement, which dulls throttle response and gear changes. The RS-spec design uses a firmer 65A rubber compound, originally developed for Porsche’s Rennsport (RS) models, to deliver sharper, more connected driving dynamics without adding harshness.
- With these mounts installed, your engine and gearbox stay properly aligned, improving stability under acceleration, cornering, and braking. You’ll experience crisper shifting, reduced vibration, and improved handling precision, especially during spirited or track driving.

Solid engine and transmission mounts are a smart upgrade to any track or aggressive street car, and were installed on Porsche factory race cars. Stock mounts are made of compliant rubber, and contribute to imprecise shifting and inferior throttle response. Solid mounts create slightly more interior vibration than rubber mounts, but securely connect the engine and transmission assembly to the car's unibody, creating a crisper throttle response and shifter feel. Rennline's solid mounts are CNC machined from 6061 aluminum for strength and light weight, and come with new Grade 8 mounting hardware.
Rennline mounts install easily in both the transmission and engine mount locations for all 1971-89 911's, and in the engine mount locations only for pre-1971 911's. Motorsport Product.

The engine mount bracket, often referred to as the engine bar or engine carrier, forms a vital structural link between the engine and the chassis. It supports the full weight of the engine through the engine mounts while maintaining precise engine alignment. This ensures smooth drivetrain operation, reduces vibration and prevents unnecessary stress on surrounding components.
Whether carrying out a complete engine rebuild, replacing damaged components or restoring your Porsche to factory condition, this OE Match engine bar provides the strength, fit and reliability expected of an original equipment replacement.
What Does the Engine Mount Bracket Do?
The engine mount bracket is a structural component that
supports the rear-mounted engine and connects it to the vehicle through the
engine mounts. It performs several important functions:
- Supports the weight of the engine.
- Maintains correct engine and transmission alignment.
- Transfers engine loads safely into the chassis.
- Works with the engine mounts to reduce vibration.
- Maintains proper drivetrain geometry.
- Helps protect exhaust, gearbox and drivetrain components from excessive movement.
Without a correctly aligned engine carrier, the engine cannot be securely mounted within the chassis.
Why Does the Engine Mount Bracket Need Replacing?
Although manufactured from heavy-duty steel, the engine
carrier can become damaged over time through:
- Corrosion caused by age and moisture.
- Accident or impact damage.
- Fatigue from decades of engine loading.
- Distortion during previous repairs.
- Damage caused by failed engine mounts.
- Cracking around mounting points on high-mileage or competition vehicles.
During major engine restorations, replacing a damaged or corroded engine bar ensures the engine is correctly supported and aligned.
Symptoms of a Damaged Engine Mount Bracket
Common signs include:
- Excessive engine movement.
- Engine vibration under acceleration.
- Misaligned engine mounts.
- Clunking noises from the rear of the vehicle.
- Difficulty aligning the engine during installation.
- Visible corrosion, cracks or distortion.
- Premature wear of engine mounts.
If the bracket shows signs of structural damage, replacement is strongly recommended.
When Should the Engine Mount Bracket Be Replaced?
Replacement is advisable when:
- Carrying out an engine restoration.
- Replacing worn engine mounts.
- Corrosion has weakened the original bracket.
- The bracket has been bent or damaged.
- Accident repairs require replacement.
- Cracks or fatigue are visible around the mounting points.
Replacing the engine carrier alongside new engine mounts helps restore factory engine positioning and long-term reliability.
