Using the same design as the standard TLR wheels, the Stiffezel front wheels have been molded from stiffer composite, which allows the wheel to flex less under higher load. During testing, the team has found these wheels to create more consistency high speed, while adding more steering in longer, high load turns. The best analogy used by a tester was, "The Stiffezel front wheels make it feel like I tightened a servo saver, even though the 22's don't have one."
