When I had lowered mine for the first time (apx -65mm), it was rubbing like hell on every corner. I had to raise it 10mm and now only rubs on full lock. There are 2 places where your car is gone rub. As you can see from the photo below, one is the random bulge in the arch lining. I just cut/grinded it away.
Second place where it might rub is the arch lip+ arch lip lining. Once again a bit of angle grinding should sort that out. But do have a play around with the coilover heights, as its sometimes better to have the car 5mm higher, then have to grind half the arch away. Personally I've spent about 4 hours just tweaking the ride height and stiffness of the coilovers. Always adjusted it, took it for a spin to my favourite big roundabout (to see if it rubs under hard cornering), and then adjusted it again if required. Has been running the same height since and its perfect.
