I had a used M-10 from a CMX installed by a shop early this winter, they didnt get it in there right. I heard Fastraxx knows the M-10 real well so I called him for guidance. He gave me some measurements, I checked them and re did the rear mount, it didnt fix the problem, I called Fastraxx back, we ran thru some more measurments and stuff, he determined the skid was to far back in the tunnel and the track was getting to tight. I moved the whole thing forward almost 2 inches and whamo, it works, that guy rules. Thanks.
