The Tamiya Porsche 959 is one of the most iconic RC car kits ever released. First launched in the 1980s, it captured the heart of enthusiasts with its striking body shell and advanced all-wheel-drive chassis. Even decades later, these kits are built, raced, and collected. But like any RC car, parts wear out, break, or simply need upgrading. Finding the correct spare parts can be a challenge, especially since the model has seen several revisions. This guide covers everything you need to know to keep your Tamiya Porsche 959 running at its best.

Understanding the Tamiya Porsche 959 Chassis
The Tamiya Porsche 959 is based on the CC-01 or, in some variants, a custom chassis. Early versions used a specific wheelbase and suspension layout. Later re-releases often include updated parts like oil-filled shocks or different gear ratios. Knowing which version you have is critical when ordering spare parts. The kit number (usually 580??) helps identify the exact variant. Common numbers include 58038 (original) and 58481 (re-release).
Key Differences Between Versions
- Original 58038: Used plastic bushings, friction shocks, and a two-piece wheel design.
- Re-release 58481: Comes with oil-filled shocks, ball bearings in the gearbox, and updated tires.
- Limited editions: May feature special body colors or aluminum parts.
When sourcing spare parts, always confirm compatibility with your specific chassis version.
Common Parts That Need Replacement
Tires and Wheels
The unique low-profile tires on the Porsche 959 are a wear item. Original Tamiya tires are hard to find, but aftermarket options from companies like Pro-Line or JConcepts offer direct replacements. The wheel design is also specific; you need wheels that fit the 12mm hex hub used on the CC-01 chassis. Many users convert to standard 2.2" wheels for better tire selection, but that requires hex adapters.
Gears and Drivetrain
The gearbox in the 959 uses nylon and metal gears. The differential gears, main spur gear, and pinion gear are common replacements. The stock gears can strip under high-torque brushless motors. Upgrading to a full metal gear set is a popular option. Tamiya offers hop-up gear sets, but third-party machined gears are also available and often more durable.
Shocks and Suspension
Original friction shocks are basic. Upgrading to oil-filled shocks (Tamiya part 50583 or similar) improves handling drastically. The suspension arms and C-hubs are made of plastic and can crack on impact. Tamiya produces replacement arms, but aftermarket aluminum parts are stronger. Ensure the shock length matches: the 959 uses 56mm rear and 60mm front shocks typically.
Bearings
The original kit uses plastic bushings. Replacing them with ball bearings (Tamiya part 50503 bearing set) reduces friction and improves rolling efficiency. Many aftermarket sets are available specifically for the CC-01/Porsche 959. Do not forget the bearings inside the gearbox and differential.
Body Parts
The iconic Porsche 959 body is made from polycarbonate. It cracks at mounting points over time. Genuine Tamiya replacement bodies are occasionally reissued but sell out fast. Aftermarket bodies from other manufacturers may fit with minor modifications. Lexan body posts and mounting hardware are also common spares.
Electronics: Motor and ESC
If your kit still has the original silver can motor, it will eventually wear out. Tamiya still sells the standard RS-540 motor, but any 540-size brushed motor works. For brushless upgrades, you need a sensorless brushless system with a 540 can. The ESC is a separate component; many enthusiasts replace it with a modern unit for better throttle response.
Where to Find Tamiya Porsche 959 Spare Parts
Genuine Tamiya Parts
Tamiya continues to support many of its classic kits. You can order genuine spares through specialized RC hobby shops. Official Tamiya parts are labeled with part numbers starting with “OP” (option parts) or numbers like 50503. Always look for the official Tamiya logo to avoid counterfeit parts.
Aftermarket and Hop-Up Parts
Several companies produce upgrade parts for the CC-01 chassis that fit the Porsche 959. These include:
- GPM: Aluminum shocks, steering knuckles, and motor mount.
- Yeah Racing: Lightweight aluminum parts and bling parts.
- Futaba: Aftermarket servo saver and steering sets.
Check compatibility: some aftermarket parts are designed for the CC-01 and may require slight modification to fit the 959’s unique chassis layout.
Specialty Retailers
Some RC hobby stores specialize in vintage Tamiya parts. They stock NOS (New Old Stock) parts that are no longer in production. These are valuable, but often expensive. Online forums and dedicated Tamiya groups can also help locate rare parts.
Maintenance Tips to Extend Part Life
- Keep it clean: Dirt and sand accelerate wear on gears and bearings. Use compressed air to blow out debris after each run.
- Check mesh: Proper gear mesh between the spur and pinion prevents stripping. Use a piece of paper to set the gap.
- Lubricate: Use silicone grease on seals, white lithium grease on metal gears, and light oil on bearings.
- Avoid overloading: The 959 chassis isn’t meant for massive jumps. Drive within its limits to prevent breakages.
- Store properly: Remove batteries and keep the car in a dry place. Sunlight can fade and embrittle the body.
How to Identify the Correct Part Number
Tamiya prints exploded view diagrams for all its kits. You can download the manual from Tamiya’s website or find it on RC database sites. Look for the part number next to each component. For example, the steering knuckle is often part number 50502. Double-check the version: some parts changed slightly between the original and re-release. Cross-reference with online forums if unsure.
Final Recommendation
For casual running, stick with genuine Tamiya spare parts for critical drivetrain components like gears and differentials. They offer good durability and drop-in fit. For high-performance driving or bashing, consider upgrading to aftermarket aluminum parts for the steering and suspension. Always match parts to your specific chassis version. Keep a few common spares on hand (tires, bearings, and a set of suspension arms) so you don’t have to wait for shipping when something breaks. Join online Tamiya communities to stay informed about re-releases and new aftermarket parts. With proper maintenance and the right spares, your Tamiya Porsche 959 will stay on the road for many more years.
