A’PEXi proudly introduces the S1 Damper line, developed by a team of A’PEXi engineers and professional racing drivers. Riding quality and handling performance are not mutually exclusive. Almost all coil over suspension systems are designed for track use, but are not well matched for street use. In fact, most are sprung and dampened improperly for street use, which not only gives a harsh and unpleasurable ride, but also hurts grip performance when the suspension cannot conform to the terrain. To address this gap, A’PEXi proudly introduces the S1 Damper line, with a specifically selected recipe of spring rates, oil and valving for hi-performance street cars that double as weekend track machines. 100% made in Japan, with precision Japanese components. 

Characteristics

• Both front and rear have 20 steps each to adjust damping force. All vehicle types have damping force quick adjuster as their standard equipment. If the vehicles have quick adjuster located below the rear speaker board, wire dial is included as standard equipment. This makes quick damping force adjustment in street damper possible.

• Selecting the most suitable damper system for the suspension structure. On top of the traditional single cylinder sports shock absorber, for the vehicle models that could shorten the damper, it adopts dual cylinder to ensure the stroke volume. To fit the purpose of street damper, the most suitable structure is chosen for every vehicle.

• High quality material. Strut type bracket have chosen to use steel for its strength. Galvanizing the metal to create rust-preventing to en...

• High quality material. Strut type bracket have chosen to use steel for its strength. Galvanizing the metal to create rust-preventing to ensure durability. Erected type adopts strong aluminum alloy to achieve both strength and light weight.

• Upper mount. Upper mount is also chosen to suit specific vehicle’s suspension structure. The reinforced rubber mount is the best to lower the noise which is needed in street driving but provides sporty handling. The front of the strut type is using high strength pillow upper mount that its camber angle can be adjusted.

• A full length adjustment without affecting the amount of stroke.
• Φ65 spring is best for street and winding roads drive.
• Suitable for overhaul inspection.
• Single cylinder type, inverting type Φ40, erected type Φ45 piston fitted.
