PROLINE Impact Blue Foam Inserts Pair 26mm for Micro/TC For RC Car

The Pro-Line Impact Blue Foam Inserts (Part No: PL6170) are specialized high-performance internal supports designed for 1/10 scale Touring Cars (TC) and larger Micro-scale vehicles. These 26mm wide blue foams are recognized for their firmer density and consistent cellular structure, making them a top choice for racers looking to eliminate tire "roll" during high-traction asphalt or carpet racing.

Key Features:

• Precision 26mm Width: Perfectly sized for standard 1/10 scale Touring Car tires, ensuring edge-to-edge support across the entire tread surface.
• Impact Blue Firm Density: The "Blue" designation indicates a medium-firm density that provides excellent sidewall stiffness. This is crucial for maintaining a flat contact patch during high-G cornering.
• Long-Lasting Shape Retention: Unlike standard "stock" foams that can crush or disintegrate over time, these high-grade foams are engineered to maintain their rebound and structural integrity through multiple race cycles.
• Reduced Tire "Ballooning": The firm internal pressure helps stabilize the tire carcass at high RPMs, which is essential for modified-class brushless racing where speeds can exceed 60mph.
• Micro-Scale Versatility: While primarily for 1/10 TC, their dimensions make them an ideal "upgrade" foam for various 1/14 to 1/16 scale micro vehicles that use 26mm wide rims.

Pro-Racing Tip:

When installing these into 1/10 Touring Car tires, ensure the foam is centered perfectly before gluing. If the foam is "bunched" on one side, it will cause the wheel to be out of balance, leading to vibrations at high speed. Pro-Tip: For maximum consistency, many professional racers "massaged" the foam inside the tire for a few minutes before gluing to ensure the foam has fully expanded into the tire's beads.

Note: These are "Open-Cell" foams, which provide a more progressive feel compared to "Closed-Cell" inserts. They are highly recommended for technical tracks with lots of tight transitions.
