Point

・This original suspension does not comply with the Japanese Traffic Road Law due to the low fog lamp height. For your reference, we have posted the data when the fog lamp height is adapted. Please be careful before equipping,
・The product is set up with the matching approach to characteristics of CROWN. 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 CROWN is a torque-full 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 damp force adjustment.
・New internal components allow for a wide range of settings with a large amount of damp force adjustment 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!
・If the rear shock body length is less than 368 mm, the arm lock happens
・We recommend that you install the product after matching the dimensions of each car model to the dimensions at the time of testing.
・Calculated from M4GT
●About modification at the time of installation
Cutting rear interior is required to install the damper adjustment.
If the spring is affected, it is necessary to remove some of the rear inner fenders.
