Car just looks like it is sitting high I'm afraid to lower it too much for fear of dragging the front spoiler on my driveway 
Rear wheel
Front wheel

back in the day Bruce Anderson used to recommend fender heights of 25 1/2" front and 25" rear, That would provide a slight nose down stance
16 w/ 205/55 and 225/50 were o.e. fit on most SC & Carrera, It appears that you have 7 & 8 x16 which is a nice upgrade but doesn't effect suspension specs
'75-'83 US 911 had unnaturally high suspension spec
normal is 108+/5mm front and 12+/5 rear, but depending on intended use lower has been spec'd requiring other mods to accommodate depending on how low the car is
if you lower yours do include a corner balance
