Stewards have thrown the book at old rivals Mark Skaife and Russell Ingall for an extraordinary confrontation that overshadowed Marcos Ambrose's maiden V8 Supercars championship title - and Ford's first since 1997 - at Eastern Creek Raceway.

Ambrose backed up from Sunday's 150km race victory to win the 250km final round finale from Holden's Jason Bright and Ford's Max Wilson.

But his victory was marred by an ugly incident involving his Stone Brothers Racing teammate Ingall and Ambrose's nearest title rival, Holden's No.1 driver Skaife.

The dust-up, which occurred with 22 laps remaining, had a dramatic effect on their final season standings.

Skaife was sent spinning into the wall - effectively handing the title to Ambrose - when he and Ingall tangled as he overtook on the back straight on the 42nd lap.

Five-time touring car champion Skaife climbed out of his car and waited beside the track for Ingall to come past again, shaking his fist and abusing the Ford veteran who is nicknamed The Enforcer.

Ingall appeared to veer toward the gesticulating Skaife before straightening again. The run-in didn't end there - Skaife's Holden Racing Team later claimed that Ingall "gave a one fingered salute" next time he passed HRT's pit bunker after a compulsory tyre change.

And Skaife stormed into SBR's pits to remonstrate over Ingall's driving. For the incident that occurred on the back straight, Skaife was deducted 30 points and Ingall 70 by stewards after a hearing that lasted almost five hours.

Skaife was also deducted 105 points, fined $10,000 and received a three race ban suspended over 12 months for ignoring officials and remaining trackside to abuse Ingall.

Ingall copped a $15,000 fine, had all 150 points accrued for the round excluded and also received the three race ban suspended over 12 months for veering toward Skaife.
