The bill-topping Bridgestone Production Car championship races produced close competition and varied results.
The opening race saw polesitter Michael Stephen (Engen Xtreme Audi S4) leading all the way, to finally win from local hero Johan Fourie (ADF BMW 335i), plus the Sasol Audi S4 entries of Hennie Groenewald and Gennaro Bonafede.
The second race, started from an inverted grid, went BMW’s way, with the ADF 335i models of Gavin Cronje and Johan Fourie leading throughout.
They finished ahead of Audi drivers Michael Stephen, Gennaro Bonafede and Hennie Groenewald.
Lee Thompson (Castrol MINI Cooper) took the first Class T race victory from Graeme Nathan
(VWSA Golf GTI), Michael van Rooyen (Williams Hunt Chevrolet Cruze), Shaun Duminy (Ford Focus ST) and Charl Smalberger (Sabertek Golf GTI).
Thompson crossed the line first in the next race as well, but his MINI was found to be two kilogrammes underweight, and he was disqualified.
That left the victory in the hands of Graeme Nathan, ahead of Charl Smalberger, Michael van Rooyen and Shaun Duminy.
Reigning champion Ben Morgenrood (IndyOil Mustang) won the first Sports and V8 GT race from Mackie Adlem (Adlem Auto Jaguar), Larry Wilford (Motul Chev Corvette), Willie Hepburn (Chev Corvette) and Steve Smith (Cool Cats Mustang).
Early leading challengers Terry Wilford (Hotwheels Mustang) and Franco di Matteo (Varta Batteries Jaguar) retired with mechanical maladies.
Di Matteo returned in race two, started from the back of the grid, and scythed through the field in impressive fashion.
He eventually finished third, behind Ben Morgenrood and Mackie Adlem.
Larry Wilford and Willie Hepburn filled out the top five places. Alan Eve (Pilot Pens Shelby)
won both the Sports Car races from Alister Brown (NAC Helicopters Shelby), with Doug MacDonald (Fantastic Shelby) and Thomas Reib (Q-Nomy Shelby) taking turns in the respective third places.
