I never got my Gmax up to 45. I had it at 40. I decided to wait until I wear out my MT to play with it more. I sold it just so it wouldn't sit around and I found a F6B rear wheel this time. The Gmax was on a regular Wing wheel.

I don't remember hearing any feedback from the buyer of my Gmax. He's a member here but doesn't post a lot. I hope it's working out for him.
