It's going to depend on the track and conditions. I was just throwing that out there because of the statement that it is "difficult" to get a TC3 lower than a 4.0:1 FDR. I run that gear ratio with 45 degrees of timing at some tracks, but it depends on the layout and how hot it is outside. Should have pointed out that I was speaking in terms of 64 pitch gears as well.
