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.


Explore the range

Explore ROHLER components for high-value Porsche restorations, air-cooled builds, engine and transmission rebuilds, motorsport-inspired projects and specialist workshop work at Design911. Match the Porsche model and year and, where possible, cross-check OE part numbers before fitting; renew critical consumables such as seals, clips and bolts and address worn mounts, misalignment or contamination so the underlying cause is resolved.

Balance shaft delete kit.

To help remove all the balance shaft belt and ancillary products on 944/968 which is only way to make the engine run smoother (After you’ve removed that stuff these bungs to plug up the holes on the engine, so it does leak from where the shafts used to be).

So, engine will still run without all that balance shaft belt and ancillary, maybe a bit rougher but will save a bit of engine power not having to drive all that stuff and engine weight. (Crankshaft/Camshaft timing is on a separate timing belt on 944/968)

The Porsche 996 Turbo and C4S model was designed and built with high performance braking in mind. However, this amazing platform has now become a popular vehicle for the track use. With track racing comes the needs for improved braking over what the stock 4piston 330mm brakes can handle. Brake engineering at the simplest is about how you can have clamping force over a large surface area and dissipate the heat to keep the brakes from fading. What Designtek has engineered is a Plus 1 Bracket Kit which allows you to take the factory 4piston 330mm brakes and upgrade to the 350mm OEM rotors that are found on the Porsche 997 Turbo.

This bracket kit is essentially a spacer that goes between your caliper and the wheel carrier to allow your caliper to fit over the larger rotors. The larger rotors will give you increased surface area to provide you better braking and longer pad life. Our brackets are CNC machined 6061 aluminum to keep the weight down. Since this is an important safety component, we have had the brackets hard anodized. The kit includes longer bolts needed to install as well as new washers.

Each Kit is sold as a pair of fronts or pair of rears. These kits fit all 2001-2005 Porsche 996 Turbo or C4S with standard non ceramic brakes.
