What is the difference between Illumina adjustable shocks and HTS/D-Spec adjustable shocks?
A. There is no difference in terms of quality. Both series allows the owner to make adjustments to both rebound and compression damping simultaneously. Illumina series allows the owner to select from 5 settings for the rebound and compression damping. HTS/D-Spec series is a multi-use product thats the result of sophisticated piston and valving design. It utilizes a unique variable-aperture bypass, which is controlled by an adjustable slide valve. Between soft and maximum stiff settings, the adjustments are infinite and are easily made with the adjuster key. Both series are excellent for performance driving such as autocross, time attack, and drag racing.
