get a set of Kerscher struts... they use Eibach progressive rate springs,
Koni adjustable inserts and have a fully adjustable ride height....
get an uprated sway bar for the front and also get a strut tower bar too.

for the rear, get a mono ball setup, its similar to a 935 rear suspension
setup and gets rid of your rear torsion bars and uses adjustable coil overs.
also get a kafer cup brace to stiffen up the rear end...
