Ride Height

		Factory *2	Test data	Adjustable range High – Low *3	Drivable range High – Low *4
FRONT	Ride height *1	654	←	681-615	681-615
FRONT	Against stock	-25	←	0 to -66	0 to -66
REAR	Ride height *1	651	←	678 to 618	678 to 618
REAR	Against stock	-26	←	1 to -59	1 to -59

*1. Height from the road surface to the fender arch.
*2. Height at the factory is the data tested at HKS with the setting of Full Kit. (HKS’ recommended setting.)
*3. Adjustable range (However, the lowest value may not be road legal.
Even within the adjustable range, the car body, arm, etc., may come into contact. In such a case, it will be hard to drive.
Damper oil leakage or any other problems caused by low ride height settings from the factory setting will void the warranty of the product.)
*4. The drivable range is that there is no contact with the car body or arms, etc. (However, a change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.

■ Points

For the facelifted (late) model, the shape of the front upper mount has been modified; consequently, we have switched from a design that reuses the stock rubber mount to a reinforced rubber mount specification that incorporates a dedicated upper plate.
Rather than simply applying the settings used for the pre-facelift model, we have recalibrated the suspension specifically for the facelifted model, utilizing the latest tuning techniques to ensure optimal performance suited to the vehicle’s evolution.
When using stock tires and wheels, setting the front shock body length to 313mm or less will cause interference with the fender during full-lock steering and full-bump compression; please exercise caution if lowering the vehicle height.
Similarly, setting the length to 301mm or less will result in interference with the inner fender during full-bump compression.
Units are shipped with the ride height set for the automatic transmission (AT) version introduced in the facelifted model; for manual transmission (MT) vehicles, adjusting the height to our test specifications will yield the best performance.

*1. When changing the front spring rate, the free length of the spring changes from 200mm to 220mm. Please note that this reduces the available range for lowering the vehicle height (adjustment range); kindly acknowledge this before placing your order.
