Hello to all back from a long vacation and glad to be back in the 550 beast. Just had a quick ? what is the exact offset for 20" wheels? I have heard the right offset for the F10 is 32 to 40 mm for the front and 35 to 40mm for the rear. I bought some wheels and the front offset was 35mm and they rubbed on the front brake caliper. I am about to get some other wheels and really want to do it right the first time in. Thanks for the help gentlemen and ladies..
