Tell us your favourite South African track — as a racer or spectator — and why (corners, vibe, facilities, visibility). Examples: Kyalami, Killarney, Zwartkops. Also: what are the best up-and-coming race weekends in 2026 for spectators (series + venue + month if you know), plus tips like where to stand, what time to arrive, parking, ear protection, and any family/kids advice. One track + one 2026 recommendation per reply is perfect.
