GPM front adjustable spring dampers for the Tamiya DF-02 are engineered as 75mm alloy assemblies to provide consistent damping and service life. The design uses robust alloy collars and mounting screws to maintain setup under repeated running. Adjustable preload lets technicians and experienced hobbyists tune ride height and initial response for specific track conditions.
During installation confirm correct thread engagement and clamp seating to prevent movement under load. Establish a baseline spring preload and refine in small steps while testing on the intended surface to achieve predictable handling.
