As I saw some people complained the new Z suspension was TOO SOFT, I would like to take some deep look at it!!!
Believe it or not, after I take some research from Internet, I can guess the ride frequency of the car!!!
First, I check the spring rates of RSR Ti2000 DOWN springs for the car which are usually 10-20% stiffer than OEM springs. 10-20% stiffer springs usually increase higher 5-10% ride frequency. I also have my own excel sheet to calculate the ride frequency of the car...You can reference the below video. (Actually, I'd already have my own calculate formula and data before I saw this video!!!
After I saw this video, I confirmed my existing formula and data were correct!!!)







When I bought it in around 2020, it's only around 3250USD!!!)
