REAR SUSPENSION SYSTEM


  1. CONSTRUCTION


    1. Rear Shock Absorber Assembly


      1. Graceful riding comfort and a high degree of handling stability with a feeling of oneness with the vehicle help enhancing by the adoption of wide-bore pistons for the rear suspension support assembly.

      2. Linear, highly responsive damping characteristics have been produced from the very-low-speed range through the pressure-reducing effect of a large-bore piston and by layering several kinds of different-diameter leaf valves with clever piston shapes.

      3. Internal pressure fluctuations during the switch between pushing and pulling have been suppressed to the minimum and responsiveness has been further improved by layering different-diameter leaf valves on the piston's upper chamber side and sharing the damping force on the pushing side with the base valve side.

      4. Linear, highly responsive damping from the very-low-speed range has produced linear handling and a sense of oneness with the vehicle.

      5. High-dimensional handling stability can be achieved by combining the graceful ride achieved by a large piston bore and reducing internal pressure fluctuations.

      6. A rear shock absorber assembly made by SACHS was employed in accordance with specifications. High-dimensional handling stability and ride quality were both established in pursuit of damping.

    2. Rear Upper Arm Assembly and Bush


      1. Cast iron has been adopted for the rear upper control arm assembly, achieving higher rigidity.

      2. A ball joint has been adopted for attachment to the rear axle carrier sub-assembly, enhancing support rigidity.

    3. Rear Lower Arm Assembly and Bush


      1. Tubing has been used for the toe control link sub-assembly in order to further enhance high rigidity and reduce weight. A ball joint has also been adopted for attachment on the axle side.

      2. Pressed steel sheet has been used for rear No.2 suspension arm assembly in order to further enhance high rigidity and reduce weight. A bush with external cylinder for attachment on the member side and a pillow-ball for attachment to the axle side have also been respectively adopted, enhancing a high level of support rigidity.

      3. Front bush with external cylinder has been adopted on the rear trailing arm assembly, enhancing excellent riding comfort by enhancing front-rear compliance.

    4. Rear Stabilizer Bar


      1. A solid rear stabilizer bar with a diameter of 15.0 mm has been adopted to optimize roll rigidity.

      2. A design for the stabilizer link sub-assembly has been adopted that uses a ball joint for the upper portion and a bush for the lower portion, and attaches to rear No.2 suspension arm assembly.

      3. Self-lubricating rubber has been adopted for the rear stabilizer bar bush.

    5. Suspension Member


      1. A square-shaped rear suspension member sub-assembly with closed section construction has been adopted.

      2. A high level of rigidity and excellent maneuvering stability have been ensured for the attachment parts of each suspension arm.

      3. A cold-forged iron rear suspension member rear upper stopper has been adopted, increasing rigidity to improve the feel of direct control as a sports car.
