correct pcd adapters

hi

i'm currently running a set of bbs rm's ( 15x6.5 ) but am changing to a set of d 90's, that are 16 x 6 with an et of 52.

for the right look should i get a 15mil or 20 mil pcd adapter kit?

thanks in advance

20s should put the wheels about bob on with the arch profiles, and it gives a little more meat to screw into. which you will need...

cheers pal, i'll run with that so
