Point

・This coilover reduces the fluffiness and roll while cornering, allowing the driver to enjoy a more stable ride.
・Longer front springs (L=250) are used for ride comfort. By changing to shorter springs, the lowering range can be increased.
・Damper adjustment dials for testing: Front 12 click/ Rear 13 click (recommended dials)
・If the front shock body length is extended beyond the maximum allowable length, the lower arm and stabilizer will be interfered.
