I see that now. Since I have run in DSP last year, I only looked in both DSR and DSP classes, and the NA Crossfire is in both of those. If you are running street tires and stock, then they classed the Crossfire in FS. Interesting. I'll be running in DSP again this year.

Find a NASA club. They have a different classing method, and the Crossfire stock is at the bottom of E. You can do a lot to the car and never leave E. I won E my first year, modded the car and moved up to D, and won D the second year in that class.

Good luck.
