The chassis is updated for the narrowed rear suspension setup. A corner bulkheads are mounted 8.4mm closer together. A corner arm mounts move the inner pivot pins 2.5mm closer together, which with the bulkhead positioning produces more rear traction and improves the stability of this vehicle. The chassis additionally features a unique, revolutionary front flex modification using a removable aluminum brace. The chassis is narrower to boost chassis flex and create more traction and steering. The narrower framework also prevents chassis rub during cornering to greatly help eliminate the feel associated with automobile â�stoppingâ� in mid-corner. Adjustable weight roles on both edges of this chassis offer quick & easy fat stability adjustment. CNC-machined from 5mm premium Swiss 7075 T6 aluminum.
