Not 100% how low it is, I just tweak it here and there to get the perfect fit.
These are ET12 with 5mm Eibach spacers all round, 235/35/19 front and 265/35/19 rear. You have to roll the rears though, but if you had a 255/35/19 on the back there'd be no need to. And yes they do clear Brembo's, £1770 for the set.
This is my summer set up, you can see with a 255/35/19 rear there's plenty off room, so no need to roll.
There do run aggressive so if you don't mind your rear wheel poking out 10mm, do it!
