It's another big episode of On the Grid this week as we chat to defending Australian Drivers' Champion Joey Mawson, who starts a rare Gold Star title defence in Tasmania this weekend. Matt Naulty joins us to preview Race Tasmania, including TCR and Trans Am action, and then #DoricGuy makes his return with great news - before we pull apart the NASCAR Clash in LA and discuss ways it could work Down Under. That and a whole heap more this week in another packed episode of motorsport news, views and fun!
