Evans secured his first outright Australian Rally Championship victory behind the wheel of an S2000 Corolla when he beat home younger brother Eli and team-mate and championship leader, Neal Bates.
However, the rally's closing stages were not without drama.
Evans and Bates headed into the final three stages of Heat 2 in first and second, but the pair both spun on the same corner in the treacherous conditions, dropping time to the younger Evans.
The TRD pair then had to settle for second and third for the heat, earning Evans enough points for the outright win, whilst Bates consolidated his championship lead by also finishing third overall.
Team TRD now takes a well-deserved brake before heading to Tasmania in early October for the first all-tarmac rally in ARC history, the Tasmanian Tarmac Challenge on 4-5 October.
Simon Evans, Car #1 - Toyota Corolla S2000:
"That was a very hard win in really tough conditions. The weather on those last few stages was just incredible. Eli did an amazing job in the wet, so congratulations to him. We still have a little bit of work to do on out wet set-up, but we learnt a lot today. To come back from the crash in the last round and to win, driving the S2000 Corolla as hard as we did, in extremely slippery conditions is a real testament to the whole team."
Neal Bates, Car #2 - Toyota Corolla S2000:
"The bad weather really set in during the final three stages, but to score first and third in weather like that is great for the team. We took a great haul of points this weekend as well which consolidates our position in the championship, so although we lost a little ground this afternoon when we spun, we will leave South Australia pretty happy."
