This Week on Speedway Sounds! This weekend is the first race of '18 for UC Irvine student Samantha Tan and her teammates Nick Wittmer, Aurora Straus, and Al Carter Racing at ST Racing. Samantha, Nick and Aurora will be on the show to introduce themselves, talk about their previous experiences in racing, and what they're each looking forward to in this weekend's Pirelli World Challenge Championships opener for the GTS SprintX category at Circuit of The Americas, the #TexasGP. Manager Nick Longhi also will join the show to discuss the driver ratings rule that forced ST Racing to replace originally-announced Connor Bloum with Al Carter very late in the offseason.
