The ACX G8X Strut Tower Brace is engineered to deliver exceptional rigidity and improved handling by reducing chassis flex during hard cornering. Designed through advanced generative, cloud-based modeling, the system is optimized to be one of the lightest and strongest braces available.

Direct Metal Laser Sintered (DMLS) aluminum mount points use cutting edge additive manufacturing to create CAD refined organic geometry that cannot be produced through traditional machining. The combination of generative designed aluminum and a carbon fiber center section results in extreme strength with minimal weight.

IND partnered with AptusWorks to create a unique version of this brace featuring matte carbon fiber with titanium hardware included by default.
