Patch 3 BoP Changes by Car
The Ferrari 296 GT3 gained downforce and torque while shedding mass, making it meaningfully quicker. The McLaren 720S GT3 EVO got a similar treatment, with reduced mass and increased torque. On the other side of the ledger, the Ford Mustang GT3 gained mass and lost torque. The Porsche 911 GT3 R received more drag alongside reduced mass and additional torque. Meanwhile, the BMW M4 GT3 saw reductions to both mass and torque. iRacing also updated factory setups for all affected GT3, GTE, and GTP cars.
Three GT4 cars received an important bug fix as well. The BMW M4 G82 GT4, McLaren 570S GT4, and Porsche 718 Cayman GT4 Clubsport MR all had a stability control system that went inactive during left-hand corners. iRacing Season 2 Patch 3 addresses that now, and drivers of those cars should notice more consistent handling through left-handers right away.
The standout quality-of-life addition is a new ABS highlight on the Throttle/Brake Widget. It gives drivers a clear visual cue when the anti-lock braking system is active during telemetry review. iRacing also corrected Bristol pit road settings and updated Long Beach brake markers in the same update.
If you run GT3, GTE, or GTP cars regularly, it is worth reviewing which cars gained and which lost. The competitive order in those classes just shifted. Therefore, the full release notes on the iRacing forums are worth reading before your next session.
