Arrowmax AM-040911 1/10 F1 Foam Rear Tyre Rim, 25 Shore Carbon  [AM-040911]

1/10 F1 rear foam rim

This is an RC-scale foam tyre rim intended for 1/10 formula F1 style cars, supplied as a pair for rear position use. The part uses a 25 Shore carbon-infused foam compound, a soft profile suited to higher mechanical grip demands on short, technical tracks.

Fitment and installation follow common foam-tyre practice: carefully glue the foam tyre onto the rim, trim excess material for a clean seat, and check concentricity before final mounting. Use light balancing and incremental testing to evaluate how the 25 Shore compound changes corner entry and traction.

In setup terms this rim and compound act as a tuning variable rather than a universal solution: softer 25 Shore foam increases contact conformity but will alter wear and steering feel, so pair changes with incremental adjustments to ride height, toe, and roll stiffness to find the target handling balance.
