Just finished preparing the new class letters and numbers for the Honda. The number will remain the same: 23, but the class will be different. If you remember, I ran my Miata in CSP (C Street Prepared). The S2000 will run in TIR (Street Tire). Just in case I will need to run the car in AS (A Stock), I made these letters too. Sprayed them all black, so they're better visible on the yellow car.
Later in the year I might make a new set, in a more stylish font, something resembling the one Honda designers used to set "S 2 0 0 0" on the side of the car. So far, I could not find anything that would match it.
