Self explanatory, the Tune Setup function does not appear in showcase races… This would be ok if they only featured standard road cars that have very little option for adjustment… But present a much bigger issue in endurance series for example as the default setup for many of the race cars is terrible, rather ruining the experience as you’re forced to spend a long race trying to tame a poorly setup car rather than reveling in whatever experience the showcase is meant to be giving…
