The sophisticated Illumina adjustment system was designed to provide precise tuning of street suspensions, offering the ability to set up your car’s handling for a variety of driving environments. The track-tested Illumina Series has proven to offer excellent dependability during the prolonged harshness of racing conditions, along with long-term durability in street use.

Damping Force Adjustment
With a choice of five settings from the softest (#1) to maximum control (#5) the Illumina Series allows drivers to easily change the balance, overall handling and ride quality for everything from daily driving to autocross or even drag racing. To change the damping force, simply insert the Illumina adjuster (part #TO 00102) into the top of the rod, and turn it to any of the five numbered settings.

Rebound And Compression
Damping force adjustments alter both the rebound and compression damping rates simultaneously, for consistent control.

Application - Specific Damping
Each shock or strut application has its own specific damping curve shape and range, precisely tailored to the vehicle.

Advanced Adjustable Valve Design
Illumina uses TOKICO’s sophisticated multi-stage, variable-aperture piston and valve system, combined with a five-position bypass shutter-valve. A crisp shutter-valve detent allows quick, sure selection of the five settings.
