iRacing 2023 Season 2 Patch 4 Released

The main changes are for the Mercedes-AMG GT4 with the iRacing 2023 Season 2 Patch 4 released to download in around 114MB. The German sportscar gets an improved ABS system, a slightly increased vehicle mass and fixes for issues with the fuel consumption and rev lights weren’t working as intended.

It’s a fairly small patch, as you’d expect for an update arriving later in an official season, but does also update the Brazilian Stock Car Pro Series vehicles to have the decals and branding for 2023. So you might need to tweak any custom paint schemes you’re running.

Aside from that, the Dallara F3 gets some new default set-ups, an AI tweak, and some issues with running iRFFB have now been sorted.

The NASCAR Next Gen Chevrolet Camaro and Toyota Camry are also mentioned in the download, but the updates are detailed in the release notes, so you’ll have to see if you can spot any differences.
