I would say they are too wide, esp. the rear.
By the time you have fitted adapters they will be sticking out of the arches. Have you lowered the car, and how, on
coilovers?
I have 19x8" front alloys ET45 with 10mm spacers and these clear the
coilovers by a few mm and are just tuck inside the arch nicely - any wider (i.e. with the thicker adapter you will need AND the thicker alloy) and you will be clearly outside the arch too much and it will look silly as well as being illegal I believe.
