don't have a # in length for you, car is put away for the winter. There was very little choices in length with the design I have built, it is what it is. the length was decided by max height I could mount the upper bracket. the choice in shock design is what will make the difference. Again at this point the transfer is not hindering me,I am not spinning a tire on launch and the car 60' is a 1.40 with a clutch that was not set up write.(slipper clutch style) I am confident next year will prove to be a grate year with a few changes.
