This product is an RC-scale rear foam rim supplied as a pair, intended for 1/10 formula-style models. The AM-040911's 25 Shore carbon foam gives a softer tyre profile that improves contact with uneven or technical track surfaces.
For mounting, use established foam-tyre methods: glue with a foam-safe cement, trim the tyre for a clean seat, and check concentricity before final installation. Carry out progressive track tests and minimal balancing to observe handling changes introduced by the softer compound.
Use the rim as a setup variable rather than a universal upgrade: softer foam will alter steering response and accelerate wear, so adjust ride height, toe, and anti-roll settings incrementally when changing compounds.
