We strongly advise to make sure that every component in your chassis suspensions, steering components and subframe mounts are in good working conditions as upgrading to stiffer suspensions (especially with pillow ball tops) will make suspension play and noises more noticeable and the stronger forces applied on them will make worn out mounts and bushes wear out quickly. Good condition OEM bushes or new poly bushes upgrade along with the suspensions upgrade will insure a "like brand new" ride quality.
2017 CX 9, upgrading to the inverted coil overs with thicker struts and adjustable Camber plates was a no-brainer. You won’t be disappointed.
I only wish they gave you more spring and less adjustable threaded cylinder. I am 1/8 of an inch from maxed out of adjustment at 2” drop, and I would’ve preferred to have a bigger/more of the included higher spring rate.
Spot on spring rate and good shock valving
Worth the money. They ride nice and lower the car really nicely.
