CRC ZeroFlex Carbon Fiber Carpet Knife Twenty5 Chassis

CRC ZeroFlex Carbon Fiber Chassis for CRC Carpet Knife Twenty5
Calandra Racing Concepts introduces a premium carbon fiber chassis for the Carpet Knife Twenty5 pan car dubbed ZeroFlex. This material is vastly more rigid, stiff, strong and torsionally tough than standard carbon fiber materials on the market. And when comparing Z-flex to aluminum, not only is Z-flex is stiffer, it returns to flat after a big crash. Why Z-flex? Some drivers prefer an ultra-stiff, rigid chassis on high grip tracks. This is especially true at big races on CRC’s Fasttrak II black racing carpet. ZeroFlex carbon fiber is the answer! Some companies have turned to aluminum material for a stiff chassis feel on these high bite tracks. It is stiff and relatively heavy. The designers then mill out a bunch of material in an effort to lower the weight of the chassis to get the car near the minimum weight rule. They leave enough material in the aluminum chassis to provide a heavier, low center of gravity piece. The problem is, opening up those milling windows to reduce the weight greatly weakens the chassis, making it vulnerable to twisting and tweaking. And because aluminum doesn’t like to flex and return back to flat, it bends and stays tweaked or bent. Hang out with an aluminum chassis racer at a big track and the amount of discarded, curled aluminum chassis grows like an expensive pile shiny potato chips.
