This disc brake adapter worked perfectly to upgrade my front disc from 180mm to 203mm. Unfortunately the adapter does not come with screws so the correct length screws must be obtained separately.
I needed a 160mm to 203mm brake rotor adapter, as i only had a 160mm to 180mm adapter. This product fits the bill perfectly, and at one of the lowest prices of any adapters on the internet.
