Tokico's new D-Spec adjustable struts and shocks are now available for the 2005 Mustang.The D-Spec (damping specific) series of dampers has an extra wide range of adjustment, far surpassing the range of the Illumina series. This wide range makes the D-Spec suitable for street-driven cars, autocrossing, drag racing, and road racing.
The D-Spec has the capability to be such a multi-use product by virtue of its sophisticated piston and valving design. The D-Spec has a unique variable-aperture bypass that is controlled by a single adjustment knob.
The adjustment changes both rebound and compression damping simultaneously. The D-Spec is infinitely adjustable between the full-stiff and full-soft positions, through seven full turns of the adjusting knob.
The D-Spec dampers are only sold in full sets of two struts and two shocks. Each set includes a manual offering pointers about how to adjust the dampers.
