About EPS

EPS for Porsche

Based in Miami FL, EPS was born by the desire to produce quality Porsche products to solve some of the issues that poorly manufactured parts left the consumers to address. For over 35 years, we have offered products that are both upgrades and permanent solutions to catastrophic failure of crucial parts. From the initial assessment to continuous improvement, we select the best suppliers and make it our aim to progress together and create innovations in the automotive industry.

Choosing the Right Fit for Your Porsche

Where EPS is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • EPS components are typically chosen to restore steering and suspension function when wear starts to affect feel and safety. Real-world reasons include fixing play, reducing noise, and returning the car to predictable handling.
  • Steering play, knocking, clunks on lock, wandering, uneven tyre wear, and vibration. Issues are often worsened by worn bushes/top mounts or poor alignment.
  • Allow for a full alignment check after suspension or steering work, and consider replacing parts in pairs where it affects left/right balance.
  • Inspect adjacent joints and bushes at the same time, as multiple worn parts can overlap and mask the true source of noise or play.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Engine Rebuild Parts — Engine rebuild parts are typically changed during a planned rebuild or when symptoms point to internal wear such as low compression, heavy oil use, persistent oil leaks, abnormal noises, or contamination found during inspection. Renewing critical components while the engine is apart reduces the chance of repeat strip-downs and helps restore long-term reliability.

  • Confirm you really need a rebuild by checking compression, leak-down results, borescope inspection, and oil/filter condition before committing.
  • Plan to replace chains, guides, seals, gaskets, hardware, and other hard-to-access wear items "while you’re in there" to make the most of the labour.

Engine Tuning — Porsche engine tuning parts are used to improve drivability, throttle response, and power delivery, or to support hardware changes such as intake, exhaust, or forced induction upgrades. Owners also turn to tuning to smooth out flat spots and poor running once the mechanical condition of the engine has been confirmed as healthy.

  • Before tuning, verify good compression, stable fueling, correct sensor readings, and that there are no boost or vacuum leaks; tuning cannot fix mechanical faults.
  • Monitor coolant and oil temperatures and data logs after changes to ensure the calibration remains safe for how the car is used.

Suspension & Axle — Suspension and axle components are replaced to restore handling precision, ride comfort, braking stability, and overall safety. On Porsche models this often means renewing arms, bushes, dampers, and joints when age or mileage leads to knocks, wandering, or uneven tyre wear.

  • Expect symptoms such as knocking over bumps, uneven tyre wear, vibration, pulling under braking, and sagging ride height when suspension parts are tired.
  • Have the alignment checked after significant suspension work and consider replacing items in axle pairs to keep behaviour balanced side-to-side.

Track Control Arms FRONT — Front track control arms are replaced to bring front suspension geometry, steering feel, and braking stability back to factory intent. Switching to an EPS arm can also be part of a broader front-end refresh where sharper response and durability are desired.

  • Typical signs include knocking over bumps, vague steering, pulling under braking, uneven tyre wear, and shimmy or wandering at speed.
  • Always budget for a proper four-wheel alignment afterwards and inspect related parts such as drop links, top mounts, and track rods at the same time.

Track Control Arm REAR — Rear track control arms are renewed to maintain stable rear wheel alignment and predictable handling, especially under acceleration and mid-corner load. Worn bushes or joints can let the rear of the car move around, which is noticeable on both road and track.

  • Look for rear-end steer sensations, instability over bumps, uneven rear tyre wear, knocking from the back, and poor traction when accelerating.
  • After rear arm work, a geometry check is essential, and it is wise to assess other rear links and subframe bushes because multiple worn parts often share similar symptoms.

62mm Flange IMS Bearing Upgrade Kit for “Closed” Engines with Full Ancillaries – The Ultimate Eternal Fix for Porsche 987.1 Boxster / Cayman Tiptronic Models

MUST USE OUR BORING TOOL IN ORDER TO INSTALL - 
the boring tool can be purchased or rented from us

This IMS bearing upgrade kit is engineered specifically for Porsche 987.1 Boxster / Cayman Tiptronic cars with M97 intermediate shaft housings. This version is the Eternal Fix, a patented and significantly stronger alternative to ball-bearing-based designs. The kit includes a 62mm cylindrical IMS bearing with thrust control, plus all required ancillaries—hardware, exhaust clamps, sleeves, seals and fittings—ensuring a complete and professional installation.

Fits:

  • Porsche Boxster 987 2.7L 2005 -08/08
  • Porsche Boxster 987 S 3.2/3.4L 2005-08/08
  • Porsche Cayman 2.7L 987C 2006-08
  • Porsche Cayman S 3.4L 987C 2005-08

Designed for “closed” engines, this IMS solution must be installed using a dedicated boring tool, allowing the bearing assembly to be pressed directly into the back of the engine without full teardown.

The Early 987.1 engines using the 62mm closed bearing are particularly vulnerable to IMS wear, lubrication issues and axial loading. The EPS cylindrical bearing design eliminates these weaknesses by separating axial load from radial load, making this the only true long-term IMS cure rather than a temporary replacement.

What This IMS Upgrade Kit Does

This advanced IMS upgrade:

  • Permanently eliminates the weak factory-style ball bearing
  • Uses a patented cylindrical roller bearing with dramatically higher load capacity
  • Separates axial and radial loads to prevent premature bearing overload
  • Improves lubrication via a dedicated oil-pressure feed kit
  • Protects the intermediate shaft and cam drive system
  • Allows installation without full engine disassembly (when used with the correct boring tool)

Includes hardware, sleeves, exhaust clamps and seals for a complete upgrade

Designed for long-term reliability and motorsport-level durability.

Why the Original IMS Bearings Fail (Especially on 62mm Closed Engines)

Typical causes include:

  • Ball bearing fatigue, leading to sudden collapse
  • Axial load overload, which ball bearings cannot handle
  • Oil contamination or lack of sufficient lubrication
  • Heat cycling and material fatigue
  • Seal degradation, allowing lubrication to escape

Design limitations of the early intermediate shaft system

Closed-style engines are especially susceptible because the bearing is not easily inspectable and operates under higher load.

Why the Eternal Fix IMS Upgrade Is the Best Solution

This patented system offers:

  • Over 12× the load capacity of traditional ball-bearing IMS solutions
  • True separation of radial and axial loads, preventing roller overload
  • A bearing that does not rely on side-loading, unlike conventional cylindrical or ball bearings
  • An oil-fed outer race, ensuring stable lubrication
  • A lifetime-capable design, not a service interval part
  • A 5-year warranty for confidence and peace of mind
  • Compatibility with closed engines using a precise boring tool

It is engineered to outlast the engine itself, making it the ultimate preventative upgrade for Porsche 987.1 Boxster / Cayman, manual cars.

Why IMS Bearings Fail in Porsche M96 Engines

Common causes include:

  • Lubrication starvation, leading to ball bearing scoring
  • Seal degradation, causing grease loss and overheating
  • Contaminants entering the bearing assembly
  • High engine speeds, accelerating wear
  • Age-related material fatigue
  • Inadequate internal lubrication flow in the early intermediate shaft design

Symptoms are often subtle—or non-existent—until severe engine damage has occurred.

Why the IMS Bearing Should Be Upgraded

Upgrading the IMS bearing provides:

  • Prevention of catastrophic bearing failure
  • Significant extension of engine lifespan
  • Peace of mind for owners of 986 Boxster models
  • A stronger, more stable bearing with improved lubrication path

62mm Flange IMS Bearing Upgrade Kit for “Closed” Engines with Full Ancillaries – The Ultimate Eternal Fix for Porsche 997.1 Tiptronic Models

MUST USE OUR BORING TOOL IN ORDER TO INSTALL - 
the boring tool can be purchased or rented from us

This IMS bearing upgrade kit is engineered specifically for Porsche 997.1 Tiptronic cars with M97 intermediate shaft housings. This version is the Eternal Fix, a patented and significantly stronger alternative to ball-bearing-based designs. The kit includes a 62mm cylindrical IMS bearing with thrust control, plus all required ancillaries—hardware, exhaust clamps, sleeves, seals and fittings—ensuring a complete and professional installation.

Fits:

  • Porsche 997 MK1 Carrera 2 3.6L 2005-08
  • Porsche 997 MK1 Carrera 2S 3.8L 2005-08
  • Porsche 997 MK1 Carrera 4 3.6L 2005-08
  • Porsche 997 MK1 Carrera 4S 3.8L 2005-08

Designed for “closed” engines, this IMS solution must be installed using a dedicated boring tool, allowing the bearing assembly to be pressed directly into the back of the engine without full teardown.

The Early 997.1 engines using the 62mm closed bearing are particularly vulnerable to IMS wear, lubrication issues and axial loading. The EPS cylindrical bearing design eliminates these weaknesses by separating axial load from radial load, making this the only true long-term IMS cure rather than a temporary replacement.

What This IMS Upgrade Kit Does

This advanced IMS upgrade:

  • Permanently eliminates the weak factory-style ball bearing
  • Uses a patented cylindrical roller bearing with dramatically higher load capacity
  • Separates axial and radial loads to prevent premature bearing overload
  • Improves lubrication via a dedicated oil-pressure feed kit
  • Protects the intermediate shaft and cam drive system
  • Allows installation without full engine disassembly (when used with the correct boring tool)
  • Includes hardware, sleeves, exhaust clamps and seals for a complete upgrade

Designed for long-term reliability and motorsport-level durability.

Why the Original IMS Bearings Fail (Especially on 62mm Closed Engines)

Typical causes include:

  • Ball bearing fatigue, leading to sudden collapse
  • Axial load overload, which ball bearings cannot handle
  • Oil contamination or lack of sufficient lubrication
  • Heat cycling and material fatigue
  • Seal degradation, allowing lubrication to escape
  • Design limitations of the early intermediate shaft system

Closed-style engines are especially susceptible because the bearing is not easily inspectable and operates under higher load.

Why the Eternal Fix IMS Upgrade Is the Best Solution

This patented system offers:

  • Over 12× the load capacity of traditional ball-bearing IMS solutions
  • True separation of radial and axial loads, preventing roller overload
  • A bearing that does not rely on side-loading, unlike conventional cylindrical or ball bearings
  • An oil-fed outer race, ensuring stable lubrication
  • A lifetime-capable design, not a service interval part
  • A 5-year warranty for confidence and peace of mind
  • Compatibility with closed engines using a precise boring tool

It is engineered to outlast the engine itself, making it the ultimate preventative upgrade for Porsche 997.1 Tiptronic cars.

IMS Bearing Upgrade Kit with Full Ancillaries – Essential Reliability Upgrade for 997 Porsche M96/M97 Engines

This IMS bearing upgrade kit includes everything needed to replace and enhance the intermediate shaft bearing in Porsche M96 and early M97 engines. Designed for early 997.1 manual models, this complete package includes the upgraded bearing assembly, new hardware, seals, exhaust clamps, sleeves and all required ancillaries to streamline installation.

Fits:

  • Porsche 997 MK1 Carrera 2 3.6L 2005 (engine code M96.05)
  • Porsche 997 MK1 Carrera 2S 3.8L 2005 (engine code M97.1)**
  • Porsche 997 MK1 Carrera 4 3.6L 2005 (engine code M96.05) 
  • Porsche 997 MK1 Carrera 4S 3.8L 2005 (engine code M97.1)**
**Engine (3.8) number up to M97/01 68509790 has the older IMS bearing (this product fits) and Engine number from M97/01 68509791 has the larger revised IMS. (this product does not fit)

The IMS (Intermediate Shaft) bearing supports the intermediate shaft that drives the camshafts. When the original bearing design deteriorates, it can fail without warning—leading to catastrophic engine damage. Upgrading to a modern, precision-engineered bearing significantly improves durability and long-term reliability, making this kit one of the most important preventative maintenance investments for these Porsche models.

What the IMS Bearing Upgrade Kit Does

This complete kit:

  • Replaces the vulnerable original IMS bearing with a fortified, precision-engineered alternative
  • Reduces friction and improves lubrication stability
  • Protects the intermediate shaft from premature wear
  • Prevents metal debris contamination inside the engine
  • Restores confidence in long-term engine reliability
  • Includes all necessary hardware, clamps, sleeves and seals for a seamless installation

Designed to meet the demands of both road use and high-performance driving.

Why IMS Bearings Fail in Porsche M96/M97 Engines

Common causes include:

  • Lubrication starvation, leading to ball bearing scoring
  • Seal degradation, causing grease loss and overheating
  • Contaminants entering the bearing assembly
  • High engine speeds, accelerating wear
  • Age-related material fatigue
  • Inadequate internal lubrication flow in the early intermediate shaft design

Symptoms are often subtle—or non-existent—until severe engine damage has occurred.

Why the IMS Bearing Should Be Upgraded

Upgrading the IMS bearing provides:

  • Prevention of catastrophic bearing failure
  • Significant extension of engine lifespan
  • Peace of mind for owners of 996/997/986/987 models
  • A stronger, more stable bearing with improved lubrication path
  • Reduction in maintenance costs over time
  • A complete installation solution thanks to included ancillaries

This kit is essential for any Porsche owner planning long-term stewardship, spirited driving, or engine rebuild work.
