Hello Jukka.
I`m Mario from middle Germany.
I have a V8 3,6 From 11/88.
It is lowerd approx 50 mm in the front, the rear is standard.
The Springs are from K.A.W.
The mounted wheels are 8 X 17 rims with 235/45 tires.
At the front the space between the wheel and the fender is all around the same.
The lowering of 50 mm allows the the daily use without problems.
I have not made pictures since i lowerd the car.....

Do you have in your car automatic level contol in the rear?
I think my english is not better

best regards
