Bmw Wheels On A Gs300

[oldskulwagon]

Good afternoon, want to give my extra set of wheels to my sister who has a 99 GS300.

BMW fitment Beyern mesh wheels.

19x8.5 et 40 front

19x9.5 et 45 rear

center bore is 72.56mm and bolt pattern is 5x120

Would like to ask you guys where to get hubcentric spacers. Also for the tire fitment gurus, what size spacers can I get away with to fill up the wheelwell.

Thanks in advance for any help.

Erick
