RCD-RCT-FMB Foam Buster for RC Tire Break-in Machine (RC DISCHARGER)

RCD-RCT-FMB Foam Buster for RC Tire Break-in Machine

Foam Buster attachment tuning helps you unlock more grip by dialing in your tire inserts. Above all, the goal stays simple: create a better internal fit so each tire responds the same on track.

Maximize your traction by perfecting your internal tire setup. Moreover, when your insert and carcass work together, the car feels calmer, turns harder, and holds speed through the corner.

Specifically, this tool targets 1/10 scale on-road and 2.2″ off-road tires. Consequently, you can optimize the relationship between the foam insert and the tire carcass without guesswork.

How it improves tire compliance

First, you break in stiff foam inserts in a controlled way. As a result, you increase the critical air gap inside the tire.

Then the carcass flexes more naturally and follows the track surface. Therefore, you gain a larger, more stable contact patch, especially mid-corner.

In addition, consistent insert break-in helps you avoid one tire feeling “dead” while another feels “free.” For background, you can review tire construction and carcass behavior and see why internal support matters.

Key features

• Versatile optimization: Works with 1/10 Touring Car, VTA, and 2.2″ Off-Road tire sizes and common foam densities.
• Grip optimization: Breaks in inserts to increase the air gap for better compliance and faster “ready” feel.
• Enhanced side-bite: Helps the carcass deform correctly under load for stronger corner support.
• Pro-level consistency: Helps all four tires match in internal feel, so balance stays predictable.
• Seamless integration: Fits and runs with the RC Discharger RC Tire Break-in Machine.
• Durable construction: Uses quality materials suited for repeated pit use.
