If you are looking for the best, buy Bilsrein
I have owned my 1993 LS400 for many years. I converted from electronic controlled shocks years ago due to the price of maintenance and repairs on them. I tried several combinations of shocks and springs bur even the top brands left the car feeling mushy. These Bilstein Sport shocks have transformed the cars handling. It feels firm and corners flat without being harsh. They are worth every penny.
Excellent handling and ride quality!
Replaced my stock springs with the Eibach Pro-Kit. At the same time changed my shocks/struts with Koni STR.T's. Combined my mustang handles better and rides more comfortably. This is the best of both worlds without compromise!! It may not have lowered the full 1.5" but my goal was ride and handling, not lowering - so I think it looks great and more important functions!!
