That is why those springs set the rear ride height on the high side. One of the things I learned during the evaluation and measurement of stroke and motion rations was that the FD was basically running on the bump stops with the Eibach and H&R springs.
The FD's rear tends to jack down on big whoops on the street and bumps. The major complaint on all the suspension setups was the behavior of the rear suspension. Decent ride quality, good spring rates, quiet. The last setup was my former favorite - Koni shocks with Tein H-Tech springs (~400f/300r).
Need some more miles and testing to make sure. All of them lacked something - too soft, too stiff - but mostly a poorly valved shock coupled with springs not tailored for a refined ride quality that allows the car to work over all kinds of roads as well as smooth track surfaces. I've tried about 8 different suspension setups over the last 15 or so years of FD ownership. After years of thinking about having Shaikh at Fat Cat Motorsports build me a set of custom valved Bilstein shocks, I finally did it.
