The Zwartkops based Rand Kart Club served the karters in Gauteng from 1976 until 2004 and this was certainly the most popular club in the country during that entire period.
Rand Kart Club is affiliated with the governing body, Motorsport South Africa, so Rand Kart Club membership is a good option for licensing with MSA. Membership of Rand Kart Club is free to Zwartkops practice card holders.
