Honestly, it's been a couple years, and I can't recall for sure. I seem to recall that it interfered with the knuckle. Graves may have made changes since I got my rearsets, as they were an early short-run they did for some race teams. They had a few extra sets and posted up on this forum, so I pounced on a set. Point being, they may have made alterations before selling them in larger numbers.
Then again, I did that on my Gen4, and may have just stuck with it 'cause it's easier to clean. Sorry, I wish I had a for-sure answer for you.
