Callum Walker will have the biggest learning curve of any of the rookies in this year's Dunlop Super2 Series as he makes the transition to circuit racing from Sprint Cars.
Callum Walker will have the biggest learning curve of any of the rookies in this year's Dunlop Super2 Series as he makes the transition to circuit racing from Sprint Cars.
A third generation speedway racer, Walker began racing Sprint Cars at just 16 years of age, winning feature races at his local Archerfield Speedway and emerging in recent seasons as a rising star of the sport.
However, two serious back injuries from crashes in 2018 and last Easter - breaking three lumbar vertebrae in the former and two thoracic vertebrae in the latter - prompted him to curtail his promising speedway career.
His path to Supercars may be very different to his contemporaries but it had a similar starting point. Walker grew up racing karts, where he battled against - and beat - emerging Supercars talent like Will Brown, Bryce Fullwood, Zane Goddard and Jayden Ojeda.
He will have a good steed in which to make his Supercars debut: Walker's privateer squad will lease from PremiAir Racing the Triple Eight-built Holden that James Golding piloted to impressive results last year.
