CUSCO 6A1 64S CN Coilover suspension kit SPORT S for SUBARU WRX STI (VAB)

Adoption of large-capacity "mono-tube shock". Authentic full-spec with 24-step damping force adjustment that satisfies a high level from city driving to circuit driving.

• monotube shock absorber
• 24 steps of damping force adjustment
• Newly developed CUSCO SPORT "Blue spring" adopted
• Full length adjustable vehicle height adjustment
• Ram type (inverted type) shock absorber
  *Front strut type only
• Compatible with high grip radial tires

Monotube shock absorber

• A structure in which the shock absorber body is a single cylinder. By increasing the diameter of the piston and improving the valve, etc., it generates a delicate damping force from minute inputs from the road surface, and follows even faster piston speeds. In addition, since the cylinder (tube) is in direct contact with the outside air, it has excellent heat dissipation and exhibits stable damping force characteristics.

24 steps of damping force adjustment

• 24-step damping force adjustment of ultra-precision special needle valve that enables precise settings from city riding to circuit driving

Full length adjustable vehicle height adjustment

• "Overall length adjustment type" that does not change the suspension stroke even if the vehicle height is lowered. Both fine vehicle height adjustment and high ride comfort are achieved.

Newly developed CUSCO SPORT "Blue spring" adopted

• The double shot peening process has increased the strength and greatly improved the resistance to settling, and by making the tolerance extremely small, we have made it possible to set more precisely than ever before.

Upper mount

• The strut type front adopts a camber adjustable pillow upper mount, and other than that, a camber fixed reinforced rubber upper mount is set. A center lock pillow upper mount (sold separately) can be installed on vehicles with no upper mount. Newly developed CC pillow upper mount (camber and caster independent adjustment type) is available as an option for some front strut type models.

Ram type (inverted type) shock absorber

• Only the strut type uses a ram type shock absorber in which the piston rod extends downward from the main body. It is effective in reducing unsprung weight, is strong against lateral G, and has excellent heat dissipation.
