Following the information shared and advice offered on this thread I have purchased two sets of 20mm hubcentric MTEC wheel spacers off eBay.
I have a 2006 X5 30d MSport with the 20" OEM factory rims. I'll be fitting these 20mm spacers to all fours corners of the next coming days and will share my findings/experiences.
(oh yeah, will be doing wheel balancing and full alignment at the same time).
