Webb spent several years racing in the Australian Carrera Cup Championship finishing eighth in the inaugural 2003 series.

The following year Webb made his debut in V8 Supercar as a co-driver in the endurance races for Marcus Marshall in a Paul Cruickshank Racing-prepared Ford BF Falcon.

Webb continued this involvement into 2010, having secured a former Britek Motorsport Racing Entitlement Contract for the Tekno Autosport team.

The team gradually moved forward, expanding to a second car in 2012 and matching the results Webb achieved in 2010 in the DJR fold.

Having finished third at the Sandown 500, the pairing capitalised on late drama, including a late-race penalty for Jamie Whincup, to win the Bathurst 1000.
