I installed the Zeta CRD on my 2017 MX5 RF in December 2020 (3 years and 12k miles). After watching some videos and reading everything on the Miata Forum (including all of Jerrick’s posts) I decided to install them in my garage. The installation went well. I adjusted the height to 13.75″ ride height. I did not want to go too low due to potholes and driveway clearances. When I switched out from the 17″ wheels to 16’s I adjusted the dampening. The Zeta CRD coilovers are everything I was looking for when I started researching suspension mods. The spring rate is perfect for spirited street driving and puts a smile on my face every time I get in the car. The coilovers reduced the body sway just enough for me to skip adding new sway bars. I would recommend the Zeta CRD coilovers to anyone. I am sure the high performance crowd will want to move up to the more expensive options by Meister or others but for me these are perfect.
