Conical washers for rear trailing arms

These are required if you’ve upgraded your R53 trailing arms to the lighter R56 alloy trailing arms.

Also this stainless steel conical washers allow you to fit R53 coilovers onto your R56 or JCW GP1 MINI. This ‘fills the gap’ between the R53 rear strut and R56 trailing arm, due to the R56 strut / shock having a built in bushing at the base of the strut, which extends into the trailing arm.
