SOUTH AFRICA - KwaZulu-Natal crew Clint Gibson and Gary Campbell continued to hold on to the lead in the Special Vehicle category of the South African Off-Road championship after the Nkomazi 400, round two of the championship, in Mpumalanga on Saturday (April 20).After their win on the RFS 400, the opening event of the year, fourth in Mpumalanga in their Porter was enough to keep Gibson and Campbell nine points clear of reigning champions Evan Hutchison and Danie Stassen (BAT Venom) and Nkomazi 400 winners Colin Matthews and Alan Smith (CR3).FIGHTING HARDSteady runs have kept Hutchison and Stassen in contention but the Nkomazi win rocketed Matthews and Smith up the standings.Father/son combinations took the rest of the top five places. Nick and Ryan Harper (BAT Venom) shared third place with former champions Quintin and Kallie Sullwald (BAT Venom) and are 15 points behind the leaders. Next up were Hermann and Wichard Sullwald (Porter), also former champions, and Clint Gibson’s brother Glenn and Clint Brook (BAT).Because of Class P interference in the overall results, the order in the Class A championship was slightly different. Gibson/Campbell continue to lead Hutchison and Stassen ahead of the sister car of Quintin/Kallie Sullwald and Herman/Wichard Sullwald with the Harpers completing the top five.TOP SCORESVictory on the Nkomazi 400 lifted Matthews and Smith to the top of the Class P standings. For the Johannesburg crew it was their third overall win in a Class P car after successes on the 2011 Adenco 400 in the Western Cape and the Atlas Copco Timbertrack 400 back in 2012.Matthews and Smith are four points clear of RFS 400 winners John Thomson and Maurice Zermatten (Zarco). The next event on the calendar will be the Toyota Dealer Sugarbelt 400 over May 17/18 based in Eston on the outskirts of Pietermaritzburg in KwaZulu/Natal.
