High Capacity Mono-Tube System for highest grade performance in coilover systems with 24-step damper adjustments.
With performance potential taken from our SPORT R model, the Sport S has been optimized to accommodate street use with alternate and ideal spring rate and shock valve retune.

Designed for use with performance radial tires for street use, and optimization for daily use with milder tires while seeking performance to the highest levels.

Tuned for the street, depending on the model, upper mounts are compliant sports rubber design, for the rear. Double wishbone suspension systems are featured with both front and rear rubber mount.

Large capacity pistons provide the highest level of control between damper requirement of various load speeds, registering a superb range of consistent performance and stability of comfort.

Mono-Tube Damper System
By using a very high quality, high capacity valve system, the system will allow efffective damping of low to high rate of motions effectively. Since the mono-tube design allows shell case walls can dissipate heat directly, heat related inconsistencies are eliminated.

24 Step Damper Adjustment
From Street to Casual Motorsports, 24 step adjustment can accommodate a wide range of use with optimization of vehicle dynamics.

Separate Height Adjustment Bracket
Fine tuning of ride height is possible without alteration of spring preload or stroke range changes. Assuring full and ideal stroke performance, even with lowest of ride height settings.

NEW Cusco Original "Blue Spring"
Double Shot Peened and designed with anti-sagging manufacturing methods, the Cusco Blue Springs are uniquely precise and consistent, offering a much more acccurate tuning goals.

Upper Mounts
Strut Type applications are packaged with adjustable camber, rigid upper mounts. For others a more street oriented hard rubber bushings are supplied.
For applications without upper mounts, a center-lock rigid upper can be optional.
Also for exacting needs of motorsports, an adjustable camber and caster control upper is also optional.

Ram Type Damper Layout (Inverted Piston)
For strut type applications, the front suspension feature an inverted ram layout, positioning the case and piston inverted and allowing the case to become the structrural support. This design like many high-end cars, allow for a huge improvement in rigidity and precision under high loads of braking and cornering.
This design also acts to better cooling, and reduction in unsprung weight for suspension components.
