The Ultimate Guide to Porsche Speedster Parts

Restoring or maintaining a Porsche Speedster—whether it’s a classic 356 Speedster or a modern 911 Speedster—requires a deep understanding of the parts that make these cars special. From body panels to engine components, the right parts not only preserve authenticity but also enhance performance and reliability. This guide covers the essential Porsche Speedster parts you’ll need, where to find them, and what to consider when making your choices.

Understanding Porsche Speedster Parts Categories

Porsche Speedsters have unique parts that differentiate them from standard models. The most sought-after categories include bodywork, interior, mechanical, and electrical components. Each category demands specific attention to match the original design.

Body and Exterior Parts

The Speedster’s iconic low windshield, cut-down doors, and distinctive rear deck are often the first areas needing restoration. Key body parts include:

• Windshield frames: Original Speedster windshields are notoriously rare. Reproduction frames are available from specialists like Stoddard and Restoration Design, but ensure they replicate the exact curvature and mounting points.
• Doors and doorskins: Speedster doors are shorter than coupe versions. Full door assemblies or skins can be sourced from suppliers such as Porsche Classic or aftermarket fabricators.
• Rear deck lid: The Speedster’s rear deck has a distinctive hump for the engine cover. Reproduction fiberglass or steel lids are common, but steel is preferred for authenticity on 356 models.
• Bumpers and overriders: Original bumpers are heavy chrome units. Lightweight reproduction bumpers are available if you’re building a track-oriented car.

Interior Components

Speedster interiors are minimalist but require precision parts:

• Seats: The classic Speedster seats are thin-shell buckets. Reproduction upholstery kits from companies like Autos International or GTS Classics can restore them to factory spec.
• Dash and gauges: Original 356 Speedster gauges are difficult to find. Repro gauges from North Hollywood Speedometer match the look, but consider sending your originals for restoration.
• Carpet and vinyl: Period-correct materials are crucial. Suppliers like World Upholstery offer kits specifically for Speedsters.

Mechanical Parts

Engine, transmission, suspension, and braking components are often interchangeable with standard models but require attention to detail:

• Engine parts: For 356 Speedsters, the 1.6L or 1.8L pushrod engines are common. Pistons, cylinders, and camshafts from JE Pistons or Web Cam are popular. For 911 Speedsters (e.g., 1989 model), use OEM Porsche parts for reliability.
• Transmission: The 356 Speedster used a 4-speed or optional 5-speed. Rebuild kits from Elfrink or ZF are available. For 911 models, the G50 transmission is robust but parts are still available from Porsche.
• Suspension: Bilstein shock absorbers and torsion bars are common upgrades. Original-style rubber bushings from Elephant Racing maintain comfort.
• Brakes: Disc brake conversions are popular for 356s. Use kits from CSP or PMB Performance that bolt on without modification.

OEM vs Reproduction: What Should You Choose?

One of the biggest decisions when sourcing Porsche Speedster parts is whether to go original equipment manufacturer (OEM) or high-quality reproduction.

OEM parts – These are genuine Porsche components. They guarantee fit and longevity but are often expensive and hard to find, especially for the 356 Speedster. For example, an original Speedster windshield frame can cost thousands of dollars and take months to locate.

Reproduction parts – Many aftermarket companies produce parts that match OEM specifications. Brands like Stoddard, Restoration Design, and Porsche Classic (for certain items) offer excellent alternatives. However, quality varies. Always ask about materials (e.g., steel gauge for panels) and fitment before buying.

For visible parts like trim and emblems, try to source OEM NOS (new old stock) if possible. For mechanical parts where function is primary, reproduction is often acceptable.

Where to Find Porsche Speedster Parts

Finding the right parts requires knowing the right suppliers. Avoid generic marketplaces; instead, focus on specialized retailers and clubs.

Trusted Suppliers for 356 Speedster Parts

• Stoddard: A leading source for 356 parts, including body panels, rubber seals, and engine components. Their catalog is comprehensive.
• Restoration Design: Specializes in steel body panels for 356s, including Speedster-specific items like doors and decklids.
• Porsche Classic: Offered through dealers, but limited to certain new old stock parts. Good for hard-to-find OEM items.
• Vintage Speedster Parts: A niche vendor focusing solely on Speedster trim and interior bits. Their rubber seals and weatherstripping are top-notch.

Suppliers for 911 Speedster Parts

• Porsche: Many parts are still available through dealerships or online retailers like Suncoast Parts. Use your VIN to ensure compatibility.
• Pelican Parts: Carries OEM and aftermarket parts for 911 models, including Speedster-specific items like seats and badges.
• FVD Brombacher: German specialist for Porsche parts, with emphasis on performance and restoration.

Online Communities and Forums

Join the Porsche 356 Registry or Rennlist forums. Members often sell parts or can point you to reputable sources. The classifieds on these sites are goldmines for NOS parts.

Tips for a Successful Restoration

Restoring a Porsche Speedster is a labor of love. Here are practical steps to streamline the process:

1. Create a Parts List: Start with your car’s VIN and the specific model year. Each year had subtle differences, especially for 356 Speedsters (e.g., 1955 vs 1958). Use parts catalogs from Stoddard or Porsche to identify needed items.
2. Budget for the Expensive Bits: Major items like engines, transmissions, and bodies will consume most of your budget. Set aside funds for unexpected finds like corrosion in the chassis.
3. Verify Fitment Before Buying: Reproduction parts sometimes vary. Ask suppliers about their return policy. If possible, borrow or test-fit before committing.
4. Consider Upgrades: Modern brakes, electronic ignition, and better cooling are common upgrades that won’t affect the car’s value if done reversibly. Keep original parts in storage.
5. Document Everything: Take photos during disassembly and keep receipts. This helps if you ever sell the car and useful for future maintenance.

Final Recommendation

For any Porsche Speedster project, prioritize authenticity and safety. Start by securing the major body and mechanical parts from reputable specialists like Stoddard or Restoration Design. For hard-to-find OEM trim, scour forums and parts meets. Always balance cost with originality—your Speedster will reward you with driving pleasure and potential appreciation. If in doubt, consult a Porsche restoration expert before buying expensive parts. With the right approach, your Speedster will turn heads for decades to come.
