I had a 2011 R60 ALL4 and have a set of 12.5 mm wheel spacers, and am planning on getting some 20 mm spacers for the axle it woul be best having wider than the other. Since its primarily FWD would you make the front axle get the 20mm spacers or would you go with the 12.5's in front and the 20mm's in rear bc keeps the track wider but looks like a true sportscar?

 

your all4 starts 50/50 front to rear and progressively goes to 100% front at about 80 mph IF no lateral acceleration is detected (ie turning) and if no wheel slip id detected ... either condition re-engages AWD

net of all this, in the usa, your all4 is using AWD most all the time unless you drive at 80mph or above

 

Ive always been under the impression, across multiple car communities, that spacers are really bad/hard on suspension components and everything else. Ive been really suprised at how everyone uses them here in the Mini world. I always thought you avoid spacers at all costs? Am I wrong?
