Introduction: Team Associated engineers sought to lower the CG and weight and improve handling on un-groomed outdoor tracks. The heart of the buggy is the new RWB/FWB adjustable weight bias chassis design. The innovative system allows the driver to run either configuration with the motor rearward for more traction, or shift the center diff and flip the center dogbones to run motor forward for more steering. Features: New RC8B4.1e RWB/FWB adjustable weight bias chassis design to tune rear grip vs. steering New low CG and lightweight aluminum front and rear shock towers New shorter 16mm front and rear shock bodies for lower CG and lighter weight New 6-hole 1.4mm front and 1.5mm taper rear machined shock pistons included with emulsion shock cap seals New 3-hole rear suspension arms with updated rear anti-roll bar geometry for both smooth and bumpy tracks New molded RC8B4
