Hello. I don't have a FF1600, but thought this forum might be a good place to learn about these organizations. I have a 1983 Ralt RT-5 FSV and live within an hour of Road Atlanta. I don't know if my car is eligible to run in those organizations. I'd like to hear some comments about them. Currently I race in SCCA, mostly regional races (have had a nat'l license since '84). I enjoy it, but the vintage/historic weekends are appealing. Are those three groups completely distinct? Or do they occasionally share events? Will one or two of them be more likely to allow me to race my car? If so, would it be in a big, catch-all class? (That doesn't appeal to me. I'd like to be on the track with Formula Atlantics and similar cars).
TIA.
