The rear coil spring on my coil overs are too soft and I need to increase the spring rate.
Right now the eibach coil springs are 0800.225.0800, aka 8″ length, 2.25″ OD, 800lbs. I want to increase to 900lbs. I dont want to make the car ride too stiff, so I’m looking at the other options off of Eibach’s website.
Maybe I can go to 850lb or 875lb?
