Hi Draco!
It was lowered in 1981 by Carlo Noce, the most famous italian Porsche specialist of the 70`s and 80`s. He took care of the setup of the suspension but I couldn`t tell you anything more. It was 31 years ago and we have the adjustments simply forgotten...The sticker of his workshop (Sportwagen) is still on the rear bumper (on the left of the license-plate).It wasn`t modified since then.
