The Kyosho AKA13121SR soft red foam insert is intended for 1/10 off-road buggies that need extra traction and predictable feel. The soft compound increases the tyre footprint on loose and hard-packed surfaces, giving drivers more control when steering and accelerating out of corners. It is compatible with LAZER series tyres and wheels.
Designed to withstand regular running, the EVO Impact R insert keeps its form under load while offering the compliance needed for better grip. That balance helps reduce mid-race changes and keeps lap times consistent across heats.
Made to work with LAZER series components, this insert fits into common tyre assemblies and helps stabilise handling across different track types. The Kyosho AKA13121SR is a practical upgrade for weekend racers and serious hobbyists tuning their suspension and tyre choices.
