The Kyosho AKA13121SR soft red insert is crafted for 1/10 scale buggies and aimed at improving grip and tyre conformity. Its soft profile helps the tyre follow ruts and bumps, delivering steadier lateral control without being harsh on the tyre carcass. It integrates easily with LAZER series tyres and wheel setups.
Constructed from a durable foam compound, the EVO Impact R insert balances softness and longevity for repeated race days. The material choice reduces unpredictable slips and keeps consistent feedback to the driver, making setup changes easier to evaluate.
Optimised to suit LAZER series chassis and tyre assemblies, this insert supports predictable handling and repeatable lap times. For club racers and hobbyists refining their setup, the Kyosho AKA13121SR is a straightforward way to tune front and rear balance.
