Response from Eibach regarding their springs below, interesting to note that the front is only about 7% stiffer than OEM and the rear retains factory spring rate.
Justin,
The front rates had a slight bump in rate from factory 186 lbs/in to the Eibach rates at 199 lbs/in.
We kept the rear rates same as stock which was tested at 350 lbs/in. Yes…the springs are longer.
As you lift the vehicle you will have less rebound travel so in some cases where there is a lot of
articulation you may notice the shock topping out. The only way to change that would be to find
an aftermarket shock with more travel.
