The latest ROAR and IFMAR rules don't allow for a lot of body tuning, mounting it forward will help a little. You could try trimming the rear spoiler a little at a time. For our little group, I doubt anyone would object if you bent a bit of lexan between 45' and 90' and glued or servo taped it into the gap between the front fenders. I don't think you will be happy with the 8HD, sorry.
