Fun anecdote;
The last car that had the Eibach system was my 1988 Mustang LX 5.0 HO. I had the shocks and struts replaced and got a call from the tire shop asking about the suspension. For the Fords they had a circumference tape with two marks, one for stock, one for GT front sway bars. My bar was much larger than the GT. The mechanic said; "I guess we should put in the performance struts then?" and I said; "Yeah, that's probably a good idea."
The system dropped the car about 1 1/2", it had a nice, mean stance all the way around. It was great on a smooth road but you felt everything! I used to joke that I could feel it when I ran over a dime. It stuck to the road almost as well as a go-cart. The coast of California is well known for it's strong gusty winds. Most cars sway, but not the Mustang. I had to look out at the grass and trees to tell if the wind was blowing hard.
That was a fun little car.
