Courtenay list they can do the Eibach SportLine kit:
"We can also supply Eibach Sportline springs, which lower by approximately 45-50mm on the front axle and 30mm on the rear, again depending upon model", but again, it's ony 30mm at the rear, and those are the rear springs I had on my Vectra, and it still sat a little too high.
or KW springs
2.0T-3.2, 1.9 - 2.2D 04/02 - 1130 980 35 210
which drop 35mm all round.
Any lower, and you'll probably have to look at coilovers.
