About Rohler

ROHLER for Porsche

ROHLER creates premium replacement and performance components for Porsche vehicles, developed for owners, restorers and specialist workshops that believe the smallest details matter. Design911 offers ROHLER products alongside genuine, OE Match and quality aftermarket options, supported by specialists who understand these cars.

The ROHLER story

ROHLER is defined by a straightforward philosophy: “Don't simply replace it. Improve it.” Its range extends from precision-machined titanium fasteners and engine hardware to carefully engineered replacement components, with an emphasis on superior materials, precise fitment and long-term durability. The understated design approach allows attention to detail to continue beyond visible parts to the hardware and engineering underneath. Premium materials. Precision engineering. Lasting solutions. ROHLER — Engineered to Belong.

Why choose ROHLER for your Porsche

Many Porsche components and fixings work in demanding conditions involving heat, moisture, road salt and repeated servicing, where conventional parts can eventually corrode, seize, deteriorate or become difficult to service. ROHLER develops more considered long-term solutions and, where the application demands it, uses materials such as Grade 5 titanium for their combination of high strength, low weight and exceptional corrosion resistance. Positioned above conventional aftermarket components, the brand combines modern engineering, carefully selected materials and precise fitment for restoration, maintenance and performance-focused work. Design911 hand-picks brands for their quality and suitability, helping customers select components for routine repairs, detailed restorations or carefully planned upgrades.

  • Premium replacement and performance components developed for Porsche vehicles
  • Precision-machined titanium fasteners and carefully engineered engine hardware
  • Grade 5 titanium used where applications require strength, low weight and corrosion resistance
  • Suitable for air-cooled builds, engine and transmission rebuilds and high-value restorations
  • Components intended to improve known weak points and withstand demanding environments
  • Fitment supported by supplied model coverage and relevant OE references

categories we stock from this brand

Design911 stocks ROHLER across the following categories for Porsche models. Check the supplied model coverage, model year, side or position, connector type and OE references where relevant to confirm the correct application.

Engine Rebuild Parts ROHLER engine hardware and replacement components are suited to planned Porsche engine overhauls, specialist workshop builds and projects where premium materials and attention to detail are priorities.

  • Internal wear can present as low or uneven compression, excessive oil consumption, persistent leaks, abnormal noises, low hot-idle oil pressure or metallic debris in the oil and filter.
  • Before committing to a rebuild, carry out compression and leak-down tests, inspect the bores with a scope and check the oil and filter for contamination or debris.
  • While the engine is apart, assess chains, guides, seals, bearings, gaskets and critical hardware to reduce the chance of a repeat strip-down.
  • Confirm the underlying cause, including overheating, oiling problems or coolant and oil cross-contamination, before installing replacement components.

Camshaft covers / Gaskets Camshaft covers and gaskets are renewed to restore reliable sealing, control oil leaks and protect the upper areas of a Porsche engine from contamination.

  • Heat cycling can harden or shrink gaskets, while covers may crack, corrode, distort or develop damaged sealing surfaces.
  • Typical symptoms include oil seepage, wetness around fasteners, burning-oil smells, smoke from oil reaching hot components and residue around the camshaft-cover area.
  • Do not rely on overtightening bolts; check cover flatness and sealing surfaces, use the correct torque sequence and renew brittle seals.
  • Inspect the breather or PCV system and crankcase ventilation because excess pressure can contribute to recurring leaks.

Engine Tuning ROHLER performance components support Porsche projects intended to improve known weak points, refine durability or complement carefully planned engine modifications.

  • Before tuning, confirm good mechanical health through compression, fuelling, sensor, cooling and oil-temperature checks.
  • Investigate hesitation, flat spots, poor idle, surging, inconsistent boost, misfires and abnormal fuel mixture readings before selecting components or calibration changes.
  • Check for boost and vacuum leaks and resolve mechanical faults rather than attempting to mask them through tuning.
  • Any modification should be considered as a complete system, with suitable supporting components and a calibration appropriate to the application.

Camshaft Covers Replacement camshaft covers are used where original covers have cracked, warped or can no longer provide a dependable sealing surface, often as part of Porsche top-end work.

  • Camshaft covers retain engine oil and protect camshafts and valvetrain components from dirt and debris.
  • Inspect for distortion, cracks, damaged bolt holes, brittle seals and persistent leaks that remain after gasket replacement.
  • Follow the specified tightening pattern and torque because overtightening can distort a cover or damage threads.
  • Check crankcase breathing at the same time, as restricted ventilation can worsen top-end oil leaks.

Interior & Accessories Interior components and accessories can refresh worn touch points, replace damaged trim or add practical storage and comfort features without changing the core character of a Porsche.

  • Common concerns include sticky switches, broken clips, rattles, sagging trim, worn surfaces, faded plastics and damaged hinges or handles.
  • Brittle plastics, ageing foam adhesives and water ingress can contribute to damp smells, mould or warped panels.
  • Many parts vary by Porsche model and year, so check compatibility details and part references carefully.
  • Use suitable trim tools and renew missing or damaged clips and fasteners to minimise loose panels and new rattles.

Front Monoball Shock Mounts (Camber Plates) PAIR

Fits:
Porsche 991.1 Carrera / Turbo
Porsche 991.2 Carrera / Turbo
Porsche 981 Boxster (inc Spyder) and 981C Cayman
Porsche 982 Boxster and 982C Cayman

These mounts will not fit GT3 or GT4 models

Designed for street and track use. Camber adjustment provides additional 1.1 degrees over OEM setup without need of upgrading your control arms to GT3 style. Will work on cars using factory shocks and any aftermarket setup designed to work with OEM mounts, this is the easiest and simplest way to gain camber. In addition, by making camber changes at the top of the strut instead of at the control arm, caster changes are minimized resulting in an easier setup and minimizing necessary modifications.


• Compatible with factory and aftermarket shock and spring kits (PSS10, KW etc)
• 1.1 degree increased camber adjustment range
• Precision monoball bearing, positively clamped in position
• Reduced camber changes & better handling
• CNC machined 

Upgrade your vehicle's suspension with this high-performance monoball top mount, designed as a direct replacement for the original OE top mount. By replacing the compliant rubber bushing with a precision spherical bearing (monoball), unwanted suspension deflection is significantly reduced, providing a more direct connection between the suspension and chassis.

The result is improved suspension rigidity, sharper steering response, and more precise handling, allowing the suspension geometry to remain more consistent under high cornering and braking loads. This makes monoball top mounts an ideal upgrade for performance driving and motorsport applications where maximum steering precision and chassis feedback are desired.

Please note that, due to the elimination of the original rubber isolation, increased road noise, vibration, and harshness (NVH) will be transmitted into the cabin. Ride comfort will be reduced, and suspension noise may become more noticeable during normal road use.

Key Features:

  • Direct replacement for the original OE top mount.
  • Precision monoball (spherical bearing) design.
  • Increased suspension rigidity.
  • Quicker, more responsive steering.
  • Improved handling and suspension geometry control.
  • Ideal for performance and motorsport applications.

Important Information:
This product is recommended for track use only. The increased noise, vibration, and reduced ride comfort make it unsuitable for drivers seeking OE levels of refinement for everyday road use.
