It’s almost time for Week 13! We’ve got a brand new list of both official and fun series competing as we get ready to deploy the 2021 Season 2 build. Week 13 is the bridge week between iRacing’s quarterly championships as we deploy new content and our latest build, and allows our users to compete in some new, fun, and offbeat challenges as they get ready for the next season.
New feature series for this edition of Week 13 include the Tin Top Tussle, as GT4s take on Hockenheim for the first time; the Shiny New Shakedown, featuring the all-new Super Late Model; Silly Send it, with the 1987 NASCAR Cup Series cars facing off with the Street Stocks; the GT3 Challenge (Fixed); and the Super Slide, featuring rallycross Supercars taking on dirt ovals.
