For drivers focused on lap consistency, the Kyosho 92035-56 KC Molded Inner Foam offers a dependable insert option. This pack of four yellow foams is made for 1/10 on-road tyres and helps the tyre maintain its intended profile, improving grip through corners. The 56mm size fits many standard tyre models used in club and national racing.
The molded construction resists deformation so the tyre footprint stays predictable under load. That stability translates to crisper steering and more stable exits. These inserts are a sensible swap when you need repeatable handling between runs.
Try these inserts alongside changes to tyre compound and shell stiffness to find the best balance for your track. They are quick to install and make it easier to compare different setups without changing the tyre itself.
