Removing the unpredictability of older wheel designs that flex and deform this new wheel is designed to be much stiffer and hold its shape under grueling conditions. This helps the suspension on the car work the way it was designed to and give you much more consistent performing setups.
The winning combo in this year's IFMAR Fuel 1:8th scale world championship along with AKA's Impact tires!
In more detail:Now that AKA's closed cell foams have become a part of everyone's product line it became apparent to us that all the current wheels are too soft compared to the now stiffer inserts and the ever increasing G forces of modern 1:8 buggy chassis. The goal was to achieve a stiffer wheel without sacrificing weight or durability. Mark and Gil were able to reach this goal by first changing the face of the wheel from convex to concave. This design change helps the EVO wheel deal with the ever increasing G-loads of a modern 1:8 buggy without distortion of the face of the wheel. Next they were able to kill two birds with one stone by developing an optional internal dish which serves two purposes. The first and most important purpose is to further stiffen the wheel and especially help the inner most bead of the wheel hold it's shape. The second purpose of this dish is to block dirt from being trapped within the inner ribbing of the wheel and throwing the wheel out of balance. These design innovations allowed the wheel to be stiffer without going to stiffer and therefore more brittle plastic or increasing wall thickness which gives up clearance and adds weight at the outer edge of the wheel. The advantage of the stiffer EVO wheel shows up immediately on rough tracks, high bite tracks, tracks with large jumps and tracks with high speed sections.
