The biff is back, with Supercars set to announce a series of rule changes that will encourage a metal-on-metal championship battle.
All 25 Supercars drivers will be told today of sweeping changes at a briefing in Adelaide before this weekend's season-opening Clipsal 500.
There will be no "draconian penalties" for contact and each driver will be entitled to a "get out of jail free card" for minor contact.
The controversial redress rule that cost Jamie Whincup last year's Bathurst 1000 - and sparked a three-car crash and a legal battle - has also been abolished in a bid to spark more on-track action.
"While the redress/repositioning adopted in 2016 has been abolished, two competitors do have the option to manage minor misdemeanours between themselves and only in rare, isolated circumstances," the Supercars organisation said in a statement. "They might avoid race control sanction if the stewards are satisfied the affected party wasn't adversely affected, or wasn't pushed off the defined circuit and/or lost positions."
