We've decided to go with a quality lowering spring instead of coilover for the 2016+ Civic Si and Type R as they have electronic damper. Electronic damper is great as it allows an easy change to feel and ride quality. Lowering springs will provide better performance and overall looks compared to stock springs.
Drop - Front - 0.9" / Rear 1"
Spring Rate (Front) - 3.1K
Spring Rate (Rear) - 4.5K
NOTE** Professional installation is required. No instructions are included. Thorough knowledge of suspension is necessary. Alignment is needed upon completion. Rear camber kit may be needed as well.
Available for both 2016+ Civic Si (Coupe/Sedan)
