I have owned 3 G11s and 4 GM8s and with each of these mounts I have always made sure to include this upgrade. Why you ask? The answer is simple, These are great additions making the grip and rotation of each clutch easier to manipulate ( I also like the way the look, Beefer). Naturally, you can keep the stock knobs but I highly recommend you step up and buy a set of these Babies, YOU will love em!
