Alex comes from a true motor racing family. His father Richard and late grandfather Lex Davison have seen much success in open wheel categories. Alex's motor racing career began when he served his driver apprenticeship racing karts where he won the 1995 Australian Karting Championship. 2010 is Alex's second year with Stone Brothers Racing and in the #4 IRWIN Racing Falcon.

Shane spent his formative years racing ATVs on natural terrain motocross tracks and a Quarter Midget on speedway ovals before a brief but typically successful dalliance with karts. Since then he has been on a fast track to major Australasian success. In 2010, driving the SBR #9 SP Tools Racing Falcon, Shane has already shown signs that have marked him as a future star of V8 Supercars.
