24mm Shaped Inner Sponge, Tire Insert Pair

These 24 mm shaped inner sponges are designed for use inside rubber tires on 24 mm wheels, adding a tuning element that changes how the tire supports itself on the track. Supplied as 2 inserts, the set is built for medium narrow tires and uses a green color code to identify the medium firmness setting quickly during setup. The internal shaping matches the tire cavity more closely than a plain ring, so the insert supports the tire from within as load shifts through acceleration, braking and corner entry. Medium firmness sits between soft and hard options sold separately, giving a balanced starting point when the goal is to adjust grip without moving to either extreme. The data also notes a direct handling trade-off: a tighter insert delivers less traction, while a softer insert increases traction and also increases tire wear. Compatibility covers a wide range of on-road chassis including TA07 PRO, TA08 PRO, TA06, FF-04 EVO, FF-03, TB-03, TB-04 PRO, TB-Evo.6, TB-Evo.7, TC-01, TRF419, TRF419X, TRF420, TT-02 TYPE-S, TT-02 TYPE-SR and F103GT. The inserts are used in combination with medium narrow tires and wheels, including available tires 51023, 51049, 53433, 53705 and 54256.
