Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive.
Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.)
*4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.

Point

・This coilover reduces the fluffiness and roll while cornering, allowing the driver to enjoy a more stable ride.
・Damper adjustment dials for testing: Front 12 click/ Rear 12 click (recommended dials)
・Note that even with the stock tire wheel (BRIDGESTONE/ECOPIA EP150), the tire and fender will be interfered before the range of motion of suspension arm.
・Note that the vehicle height (minimum ground clearance) will be lowered by 10 mm with stock tire wheels.
 Test data shows that the lowest ground clearance can be achieved even with stock tire wheels, but please note that this may not be the case depending on individual vehicle characteristics.
