Point
Utilizing characteristics of SUV, slight lowering the vehicle height provides mature and stylish low style without the stereotypic images of tall height vehicle.
Unstable cornering which is typical of SUV is maintained, and this product is able to withstand the FA20 engine performance both for sports and street driving with the selected spring rate.
With this product, the vehicle height is adjustable to the stock level when the vehicle height is required to be properly set to drive on a snowy road. (Front: -4mm of stock)
Increase the spring rate to suppress a sinking degree of a vehicle body when loading many luggage into a vehicle.
