Im not selling it..
Went for a ride earlier, I must say it isnt as good as having it on my actual brake mounts, but it does still give me alot of stiffness, alot more than this GU is without a booster, and i prefer it if im honest to having it crammed up ontop of my mounts.
Thanks for all your advice
Oh yeah, if you was to want to do this, I wouldn't... Its only because its already done why im keeping it..
