iRacing 2020 Season 4 Patch 4 Released

You’ll need to download the latest update before you can get back to competitive sim racing with iRacing 2020 Season 4 Patch 4 released now.

One of the new features highlighted by iRacing themselves is the fact that you can now use the AI single player races with the NASCAR Xfinity series, along with Rockingham Speedway Oval.

But possibly more important for many drivers are balance of performance adjustments for the GT3 and GTE classes. The Audi R8 LMS has had downforce slightly reduced and the Mercedes-AMG GT3 has improved downshifts with less tendency to lock wheels.

Meanwhile in the GTEs, the BMW has had downforce slightly reduced, while the Ferrari, Ford, and Porsche 911 RSR have had an increase.

Don’t forget that for iRacing 2021 Season 1, starting in December, you’ll need a higher licence class to run GT3 and GTE cars in the IMSA SporsCar Le Mans, and Endurance Le Mans Series.
