I went with Yokohama Advan A052 265/35/18 up front and 295/35/18 in the rear, 10x18" ET 28 up front and 11x18" ET 44 in the rear. Rubbed through the rear wheel liner because of Tiergarten at the Ring but that was with stock dampers/lowering springs, 3 people in the car and pretty much full tank.
With slightly stiffer suspension and not so much dead weight it will be fine. Looks the business as well. Went with this setup to be able to use MDM at the Ring without tripping the DSC so easily.
