This is the AKA Racing pair of 1/10 scale Stadium Truck Soft Closed Cell Inserts, (2).
AKA Racing is without a doubt the leading pioneer when it comes to closed cell inserts. These inserts were designed increase the vertical impact absorption while decreasing the lateral deflection of the tire, therefore providing better handling in the bumps.
Hollowing out the inner circumference or using softer foam like other companies do leaves your car or truck feeling squirmy, with a less than accurate feeling through the bumps- Not to mention the loss of durability. Gil Losi and Mark Pavidis knew this compromise was not the solution. The solution they found was the addition of lateral grooves to the inner diameter. The lateral grooves allow the insert to flex vertically to absorb the large impacts while still maintaining lateral stability and overall durability AKA inserts are known for. No compromises. The result is a more predictable handling car without giving up durability.
