A Quick Look at Porsche

Porsche information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Porsche 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.

  • Typical reasons people replace these parts include maintaining originality, keeping factory specification, and choosing the latest genuine revisions for peace of mind.
  • Common real-world issues behind many Porsche repairs are age and mileage: oil leaks, cooling system fatigue, brake and suspension wear, corrosion and electrical faults from moisture or heat cycling.
  • Before ordering, confirm part numbers against VIN or option/PR codes, especially for safety‑critical or complex components.
  • When upgrading, decide whether you want pure originality or performance changes, as some aftermarket options may suit specific goals better than genuine.
  • For bigger jobs, replace related seals, hardware and consumables at the same time to avoid repeat labour and compatibility issues.
  • Where available, follow the manufacturer’s fitting and bedding‑in guidance to get the best performance and longevity.

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.

Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include: Common symptoms include vibration under braking, increased stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.

  • Check whether the parts are OE-equivalent replacements or performance upgrades and match this to how the Porsche is used.
  • Follow any recommended bedding-in procedure and consider replacing discs, pads, sensors and fitting hardware together where advised.

Clothing & Gifts — Porsche-themed clothing and gifts let owners and enthusiasts show their passion off the road, or make ideal presents for fans of the marque. Common symptoms include: Items may become worn, faded, damaged or go out of style, prompting replacement with newer designs.

  • Review available size, colour and material details to help choose the right item and ensure it matches how it will be used.
  • Check any care or washing guidance so garments and accessories keep their appearance for longer.

Lifestyle — To explore different Porsche-inspired lifestyle products or gift ideas. Common symptoms include: General wear from handling or display.

  • Confirm whether items are official Porsche lifestyle products or from trusted partner brands where stated.
  • Consider who the item is for and how it will be used day to day to select the most suitable style or product type.

Keyring — To choose a different design, material or model theme. Common symptoms include: Scratches, worn finishes or loose fittings.

  • Keyrings make simple, practical Porsche-themed gifts and can be matched to specific models or heritage designs where available.
  • If a keyring shows damage or looseness, replace it to avoid losing keys or further wear to finishes.

Size chart — The size chart acts as a practical reference tool for all apparel purchases. Common symptoms include:

Product Information

Genuine Porsche synchroniser ring for first and second gears in the Porsche 911 Turbo (930) four-speed gearbox, covering the supplied 1975–1988 application.


Fits:
Porsche 911 Turbo 1975 - 1988 (4 speed gearbox)

Diagram ref no: 41


What This Product Does

The synchro ring works within the gearbox synchroniser assembly to bring rotating components towards matching speeds before the selected gear engages. This product is the ring for first or second gear, not a brake band or dog-tooth component.


Functions

  • Provides friction for synchronising gear speeds during selection.
  • Supports engagement of first or second gear within the specified transmission.


Technical Details

  • Brand: Genuine Porsche.
  • Gear application: 1st/2nd gear.
  • Transmission application: four-speed manual gearbox.
  • Existing product reference: 93030230100.


Symptoms of Fault

  • Crunching or grinding while selecting first or second gear.
  • Resistance to engagement or a need to pause before completing a shift.
  • Gear clash during downshifts.

These symptoms do not confirm ring wear on their own. Clutch operation, linkage condition and gearbox oil can also affect selection.


Why Replacement Matters

A worn friction surface can prevent the synchroniser assembly from matching speeds effectively. Renewing a ring after confirmed wear addresses that component during gearbox repair. Inspect the associated engagement teeth, brake bands and selector components rather than assuming the ring is the only worn part.


FAQs

Will fresh gearbox oil repair a worn ring?
No. Correctly specified oil may influence shift feel, but it cannot restore a worn friction surface.

Does double-declutching fix the problem?
It may ease the symptoms, but it does not renew damaged synchroniser components.

Which reference should I check?
Confirm the recorded part number and the relevant gearbox illustration before ordering, as the supplied product and internal diagram references differ.

Clutch slave cylinder..
Fits:
Porsche 968 1992-95
A clutch that is engaged/disengaged via hydraulic fluid instead of a cable uses a Clutch Master and Clutch Slave Cylinder. When depressing the clutch pedal a lever is squeezed, forcing hydraulic fluid through hydraulic lines to a "slave cylinder" which houses a piston. The piston forces a push rod to engage or disengage the clutch. A clutch master cylinder that contains the hydraulic fluid sits on a support har near the clutch lever. When either the Master or Slave Cylinder fail the clutch is unable to be disengaged.
