Point

・Arm locks when front case length is less than 212 mm.
・The product is set up with the matching approach to characteristics of SILVIA. By making the suspension suppler, it tracks better with the road surface, which reduces unnecessary movement and improves the ride comfort on the street.
・In sports driving, the car's movement can be easily felt by actively shifting the load, and the control can be safely enjoyed by suppressing abrupt movements at the limit range. It is also recommended for beginners to practice sports driving.
・Since SILVIA is a highly sporty rear-wheel drive vehicle, we put effort on rear stability and have set the rear suspension to a weak understeer setting. If you want to move actively to oversteer, please tighten the rear dial.
・New internal components allow for a wide range of settings with a large amount of dial variation.
・Due to the installation of insulator springs in the front and rear, it is easy to adjust the vehicle height.
・High durability of 3-year/60,000 km coverage has been achieved by reviewing internal components.
・Please experience the evolved HIPERMAX!
