Super Precise 1/10 RC Touring Car Setup Wheels

Proper chassis setup is one of the most overlooked yet most impactful aspects of 1/10 scale touring car performance. Ride height, droop, camber, toe, and tweak adjustments are only as accurate as the reference you measure from. These 3D printable setup wheels are designed to give you a repeatable, stable and highly precise reference, allowing you to dial in your car with confidence—on carpet or asphalt.

Why setup wheels matter

Using normal race wheels for setup introduces multiple sources of error:

• Tire deformation under the car’s weight
• Inconsistent tire diameter between sets
• Uneven wear
• Sidewall flex that changes camber readings

Setup wheels eliminate these variables entirely. By lifting the chassis onto rigid, dimensionally accurate wheels, you create a neutral baseline. This ensures:

• Accurate ride height measurements
• Consistent droop settings
• Reliable camber and toe readings
• Faster, more repeatable setup changes at the track

Simply put: setup wheels turn guesswork into data.

Why these setup wheels

This design is engineered specifically for precision and practicality:

• Accurate geometry
  Designed for tight tolerances to ensure all four wheels are identical in diameter and width, critical for correct tweak and droop measurement. There's a little cutout in the rim of wheel where the o-ring sits; this is where the print seam will be located so the bulb of the seam does not interfere with the o-ring and won't make the wheel slightly larger at that point.

• Fast mounting

  The hub of the wheel is slightly raised so only a few mm of the axle sticks out. This way you can very quickly screw on the nuts that hold the wheels.

• Integrated O-ring interface (62×57×2.5 mm)
  Uses a common off-the-shelf O-ring to create a controlled, non-slip contact surface.
  This prevents sliding on setup boards while adding slight damping—protecting your setup surface and improving stability during adjustments.
• Lightweight but rigid construction
  Optimized wall thickness for stiffness without unnecessary mass, making the wheels easy to handle while remaining structurally stable under chassis load.
• Designed for 1/10 touring cars
  Compatible with standard 4mm axles.
• Perfect for home, pit lane, and race prep
  Whether you’re building a base setup, fixing tweak, or comparing changes between runs, these wheels help you work faster and more accurately.

Printing notes

• Print all four wheels using the same material and settings for maximum accuracy
• PETG recommended for dimensional stability
• No supports required
• O-ring: 62×57×2.5 mm (standard, widely available) > https://a.aliexpress.com/_EG2TB5I

NOTE: There's a little cutout in the rim of wheel where the o-ring sits; this is where the print seam will be located so the bulb of the seam does not interfere with the o-ring and won't make the wheel slightly larger at that point. 

If you take setup seriously and want consistent results from your touring car, these setup wheels are a small print that delivers a big performance advantage.
