These are the insert foams for Ultimate Racing. These foams are designed to fit into each of the slots of the inserts. Once installed, the insert is practically secured to the rim. This prevents the insert from moving during lateral grips, enhancing stability in fast corners.
It also prevents the insert from centrifuging, which helps the tire to centrifuge less. With less centrifugation, the car becomes much more stable during acceleration.
They can be used on most inserts, wheel brands, and compounds, but their effects are greater on soft compound wheels.
Depending on whether we want the insert to be more or less secured, they can be used in all three slots, in two, or just in one.
They are sold in bags of 50 units, allowing us to equip between 4 to 12 complete cars depending on the number of foams used per insert. Once the tire's life is over, they can be reused as many times as desired.
