Raffaele Marciello has topped final Friday practice in Bathurst, which was cut short due to a major incident at The Chase.
Marciello’s 2:03.9958s proved the best of a session shortened due to a crash for Keith Kassulke.
Kassulke (#52 MARC) suffered a suspected mechanical failure as he approaching the braking zone of The Chase.

The #52 II V8 careened into the tyre barriers, with barrier damage ultimately ending the session.
Kassulke ended up on his roof, such was the severity of the impact.
The incident occurred midway through the 40-minute session. The session was later declared as crews attended to Kassulke.
Kassulke was communicating with recovery crews during the stoppage.

The Italian was the only driver of the day to clock a 2:03s lap time.
Jules Gounon (#75 Mercedes-AMG) was second with a 2:04.1362s ahead of Mathieu Jaminet (#912 Porsche).
A total of 25 cars took part in the session, with the #66 SIN R1 not taking part.
An engine failure in the #50 KTM also forced M Motorsport/Vantage Racing to switch cars.
The team swapped into a spare Audi prior to Practice 4 in order to take part in the weekend.
