Frequently Asked Questions
- What is a shim used for in RC cars? — Shims are precision spacers used to fine-tune the spacing and alignment of components in your RC vehicle. They are commonly used to adjust bearing preload in the drivetrain, create proper clearance in the transmission, and ensure suspension components sit at the correct angles for optimal performance and handling.
- Why would I need replacement shims for my RC model? — Shims may need replacement if you're rebuilding your RC car, adjusting setup for different driving conditions, or if original shims have become worn or damaged through use. Having spare shims in various sizes allows you to make precise adjustments without having to disassemble large sections of your vehicle.
- How do I know if this shim size is right for my RC car? — The 12.1x19.5x0.3mm dimensions are specific to certain ARRMA models and applications. Check your vehicle's manual or assembly guide to confirm which shim sizes are required for your specific RC car. Having multiple shim sizes in your collection gives you flexibility for tuning and maintenance.
- Are these shims compatible with other RC brands? — While these are ARRMA shims designed for ARRMA vehicles, the 12.1x19.5x0.3mm size may work in other applications. However, for guaranteed fit and proper function, it's best to use shims that match your specific RC vehicle's requirements and manufacturer recommendations.
- How many shims do I need? — This depends on your specific build and which areas you're working on. It's wise to have several of each size you use regularly, as shims can become lost or worn. Most RC enthusiasts keep a small collection of various shim sizes in their workshop or toolbox for convenience.
