Will Brown has tightened his grip on the Supercars championship after topping a crash-interrupted qualifying at the Adelaide 500.

Richie Stanaway, Cam Hill and David Reynolds made the same mistake on the same stretch of track within seconds of each other, resulting in a red flag halting the session soon after it began on Friday afternoon.
