Genuine Tamiya Parts vs. Aftermarket Options
Tamiya still produces many parts for classic kits like the Porsche 959, but availability varies. Genuine parts ensure perfect fit and original performance. Aftermarket parts often offer improved durability or customization. Here’s what you need to know for each major part category.
Chassis and Frame Parts
The 959 uses a resin monocoque chassis (part no. TC-01 or based on the RC version, depending on your kit—the static display kit differs from the RC version). For static kits, the chassis number is usually printed on the sprue. Common replacement parts include:
- Main chassis tub: Genuine Tamiya #94078 for the RC version; for the static kit, check the manual for the specific number.
- Battery holder and motor mount: These are often interchangeable with other Tamiya 1/10 scale cars, but double-check screw spacing.
If you’re missing the original chassis, aftermarket carbon fiber upgrade chassis are available from companies like Yeah Racing or Hot Racing. These reduce weight and add stiffness, but require some modification.
Body Shell and Decals
The iconic Porsche 959 body is the most visible part. Genuine Tamiya polycarbonate bodies are hard to find but occasionally restocked. Aftermarket bodies from bodies manufactures like Pro-Line or JConcepts offer lexan versions that are lighter and easier to paint. Decal sets from MCI Racing or Killerbody provide accurate reproduction decals for the 959’s Gulf- or Rothmans-style liveries.
Compatibility tip: Ensure the wheelbase (usually 257mm) matches your chassis. The 959 has a distinctive sloping roofline; cheap knock-off bodies often have poor proportions. Stick with reputable brands.
Drivetrain: Gears, Differentials, and Drive Shafts
The Tamiya 959 uses a four-wheel-drive system with front and rear differentials. Parts that commonly wear out:
- Spur and pinion gears: Genuine Tamiya #50680 (spur) and various pinions. Aftermarket steel gears from Robinson Racing or RW Racing last longer but are noisier.
- Differential gears: Tamiya #53613 for the RC version. Upgrade to ball differentials (e.g., Tamiya #53549) for smoother action.
- Drive shafts: Universal joints (Tamiya #53840) are more durable than dog bones. Aftermarket CVDs from MIP or Tekno are stronger.
Upgrade recommendation: Switch to a slipper clutch if your kit didn’t include one. It protects the drivetrain on high-torque motors.
Suspension and Steering Components
Stock plastic suspension arms can flex under power. Replacement options:
- A-arms and uprights: Genuine Tamiya #94079 set. Aluminum options from GPM or Integy add rigidity.
- Shocks: Tamiya oil-filled shocks (#53921) are a direct upgrade. Aftermarket shocks from TRF or KYOSHO may need adapter spacers.
- Steering linkage: Plastic tie rods bend easily. Titanium or steel turnbuckles from Tamiya (#53696) or Team Associated are solid upgrades.
Electronics and Motor Mounts
While not strictly Tamiya, the 959 RC kit often leaves room for aftermarket electronics:
- Motor mount: Aftermarket aluminum mounts dissipate heat better. Ensure it fits the 540 motor pattern.
- Servo saver and servo horn: Stock plastic horns strip. Replace with aluminum ones (e.g., Tamiya #53973).
Where to Source Hard-to-Find Parts
Tamiya’s official parts distributors (like Tower Hobbies) stock many items for the 959. For discontinued parts, try:
- Specialty hobby shops that carry vintage Tamiya kits.
- Online forums like TamiyaClub.com or RCTech.net: members often sell spares.
- Facebook groups dedicated to Tamiya kits. Use specific search terms like “Tamiya 959 gear set WTB.”
Avoid generic “toy parts” sellers—they often mislabel items. Compare part numbers from the kit manual.
Common Mistakes When Ordering Parts
- Assuming all Tamiya 1/10 parts fit – The 959 has a unique wheelbase and suspension geometry. Some parts from the Porsche 934 or 935 may not match.
- Ignoring revision numbers – Tamiya revises parts over years. Check if your kit is an early or re-released version (differences in chassis part numbers).
- Buying full kits just for one part – Often more expensive than searching for the specific spare.
Final Recommendation: Start with Critical Wear Items
If you’re restoring a used 959, prioritize drivetrain and suspension parts—these take the most stress. For a new build, invest in a quality set of shocks and a steel spur gear to avoid early failures. Always keep a set of spare screws and bushings (Tamiya #50500) handy. Stick with genuine Tamiya for hard-to-replace pieces like the body or chassis, and consider aftermarket for performance upgrades. With the right parts, your Porsche 959 will run smoothly for years.
