hi i tryed a set of 18" alloys on my classic with an offset of 45. they seat level with the edge of the arch at the rear ,so what is the best offset to go for (my 17's are 48)cheers j (the wheels had 225/40/18 on)

 

48 to 52 are probably the most ideal offset to use.

Tony

 

will that sit the wheels in the arches in stead of level with them cheers j
