Point

Ground Clearance: 98mm
The spring rate and dampening force were selected by placing priority on handling under sports driving and upgrading the factory setting. This product generates the gradual movement without being too peaky with the load control range especially for FR. Its supple movement stimulates tire grip and smooth riding that provides sufficient comfort for daily driving.
