The Kyosho AKA13121SR is a precision foam insert made for 1/10 scale buggies. This soft red insert focuses on improved contact with the tyre, helping to boost grip and lateral stability without sacrificing responsiveness. It is built to pair cleanly with LAZER series setups for straightforward fitment.
Made from resilient foam, the EVO Impact R soft red insert resists breakdown while providing predictable traction across different surfaces. Its softer durometer smooths out bumps and aids tyre conformity, giving drivers more confidence through corners and over ruts.
Specifically matched to the LAZER series, this insert nests neatly in the stock tyre and supports consistent handling from qualifying to mains. Whether you are tuning for grip or tyre wear, the Kyosho AKA13121SR is a practical upgrade for competitive and club racing alike.
