Eibach's Pro-Kit is their premium suspension product. These are sport lowerings springs, stiffer than the factory springs, they improve handling while lowering your car. Eibach have a drop of 0.8" front and 0.8" inch rear for years 2016+. Suitable for factory shocks.
Eibach designed one spring for the ND and they list it as fitting both the soft top and the RF model, which it does, but keep in mind that Eibach designed their springs for an even drop front and rear on the soft top model, and in our experience the RF with additional rear weight does squat more in the rear - which you see reflected in the lowering numbers Eibach quotes for the RF. We have not tried these springs here, but our concern is that in RF with two adults in the car there will be an obvious rear-biased "squat" to the ride height.
