SCCA released their revisions for July and the Model 3 now has a proper classification. D Street: https://www.scca.com/downloads/41816-2018-07-30-solo-rules-book-2e-reduced/download Page 150. Seems fair to me for the TM3 LR. However, it doesn't differentiate between the LR, Dual Motor or Performance. If they don't correct this in time for Nationals, a P3D owner with a little skill might want to consider giving it a shot.
