Dunlop Super2 Series stewards have taken no further action over the Bathurst clash between race winner Dean Fiore and Paul Dumbrell, which ended the latter's race.
The pair overlapped and then tangled on the run to The Cutting on lap four, the left-front of Fiore's Nissan making contact with the right-rear of Dumbrell's Holden.
It spat Dumbrell to the outside fence, with damage from that impact ending the two-time series winner's race.
Fiore went on to take out the chaotic affair, after Macauley Jones and Garry Jacobson - first and second at the time - had their own incident at The Chase on the final lap.
Stewards reviewed the Fiore/Dumbrell incident and took no further action, leaving Fiore with his second victory of the campaign.
"The RD (Race Director) conducted a post-Race investigation into an incident involving Car #88 Paul Dumbrell and Car #23 Dean Fiore on the exit of Turn 2 on Lap 4," read the stewards' report.
"Following a review of Television Broadcast Footage and Judicial Camera Footage from Car #23 (Fiore) and #62 (Alex Rullo), neither Driver was wholly or predominately to blame for the incident."
There was a similar outcome in the clash between Shae Davies and Zane Goddard at the same time, which effectively ended Goddard's race.
Chris Pither inherited third in the late mayhem and takes the top spot in the standings by 32 points over Dumbrell.
Brodie and Jake Kostecki were both penalised 35 points for their part in separate incidents that accounted for two of the three Safety Car periods.
Both were found guilty of 'reckless driving' and docked 35 points.
Brodie Kostecki led early but fell down the order on strategy and then collided with Jordan Boys at The Chase on lap 33.
Jake Kostecki clouted brother Kurt Kostecki at Turn 1 on lap eight, while trying to pass Matt Chahda.
Having won at Sandown in September, the DNF and points penalty mean Brodie Kostecki falls from third to fifth in the standings.
The 2018 Dunlop Super2 Series concludes at the Coates Hire Newcastle 500 on November 23-25.
