So I'm planning on making some suspension setup changes for this next auto x season. Currently running Fortune Auto 500 series coilovers with 8K springs in front and 5.3K in the rear. I will be picking up a Strano rear sway bar and some RE71R tires in 245/40/18 for the next season. I keep seeing a few people here stating a higher spring rate for the rear is better for this car. So if that is true what coilovers would do the job better than my current ones?
