The alloy subframe models have their mounting position a lot further back,if you try and mount 50mm systems on a steel subframe the SP hangers wont work.The other problem is the mounting points on the can itself are in a different position to(they`ve sort have been moved round the pipe circumference)If you have a 45mm high level system you can use those mounts,but you`ll have to mount the brackets behind the subframe as the offset is different.
