Eibach Pro-Kit Lowering Springs
I had a buddy install them for me. He had both rears done in about 35 minutes with no problem but once he took the front's off he couldn't do it. The reason was because the shocks compressed and with the Eibach spring being shorter there was no way to push the shock threw the spring. I then had to take them his friends shop that had the correct machine. Other then that I love the looks of them and the ride is so much better.

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.
