Supplied as a matched rear pair, this rim is intended for 1/10 formula-style RC cars. The AM-040911 employs a 25 Shore carbon-infused foam to boost surface conformity and rear traction on technical circuits.
Mounting follows standard practice: use a foam-compatible adhesive to secure the tyre to the rim, trim excess foam for a perfect seat, and verify the wheel runs true. Perform light balancing and incremental track checks to assess the compound's impact on handling.
Consider this rim a setup tool: the softer 25 Shore foam improves grip but changes wear and steering feedback, so make modest adjustments to ride height, toe, and roll stiffness when switching tyre compounds.
