Quickest of the 24 drivers competing in this unique week-long motor sport event, which started at WesBank Raceway in Germiston on Saturday and ends at Killarney circuit in Cape Town on Sunday, was KZN radiologist Stuart Kidgell in his immaculate Ultima, powered by a twin turbo Alfa Romeo V6 engine.
Kidgell won both the slalom-style gymkhana and a 4.5 km individual sprint around two laps of a shortened version of the 4.4 km high-speed test track and is now the overall leader of the Fidentia Fireball after three days and five events with a total time of 11 min 54.10 sec.
Second fastest in the gymkhana was Ian George in his Ford Mondeo-engined Noble ahead of Jannie Hatzi (BMW M5).
Second in the sprint was former national circuit and rally champion Geoff Mortimer (Nissan Skyline GTR, followed by former VW Polo Cup champion Tschops Sipuka in the Fidentia Nissan 350Z.
Second overall in the Fidentia Fireball and just over 36 seconds in arrears is Andre Bezuidenhout (Porsche GT2) with a total time of 12 min 30.70 sec.
Mortimer is third, just three seconds behind Bezuidenhout, while fourth is racing and rally driver Gugu Zulu in the second Fidentia Nissan 350Z (+47.9 sec), fifth Brian White in a Porsche RSR (+50.30 sec) and sixth is Sipuka (+51.20 sec).
The private battle developing between Zulu and Sipuka in the identical supercharged Fidentia Nissan 350Zs is a feature of this entertaining event for GT-type sports cars.
At this stage, with still five days of competition remaining in four cities, Zulu leads Sipuka by 3.3 sec.
Today (Tuesday) the 24 competitors travel down the east coast and through the Transkei to East London, where the next event will be on the historic grand prix circuit on Wednesday.
