Voca Racing brake caliper adapter for mounting a 4-piston Stage6 R/T caliber or equivalent at the rear. The adapter can be used on both models with rear disc and drum brakes, however, it will be necessary to mount rear wheels with disc brakes, such as Yamaha Aerox and others. As the adapter is not mounted on the original brackets, but is screwed on differently, it is necessary to drill two holes in the block to be able to mount it. Mounting instructions are included.
