ok, browsing some forums i`ve noticed people removing the face of the bbs lm wheel and "rear mounting" it as such.. as below :

rear mounted face




front mounted face





i`m wondering, if my wheels have an offset of 42, and i remove the face from front mount, and make it rear mount, although i`m getting more lip on show, just how much am i adjusting the actual offset by?

i reckon it`ll be a case of mount the wheel, see the fitment, strip and rebuild the wheel and test fit. but i thought i`d ask

 

I read somewhere that it would be subtracting 5mm to the offset so you would be at +37

 

many thanks mar
