We’ve got a TaG class at a tight, twisty track, with speeds reaching 55-57 MPH at the end of the straight.
Right now, TaG Lite has X30 at 370# and Rotax at 365#. Many of our drivers are bolting on fifty pounds of weight.
For a light driver, is there a good starting point for a fair weight to run a KA100 against the X30s? Would 310# give an advantage in some places and a disadvantage in others?
