In a slightly change to the normal Tuesday schedule, we’ve seen iRacing 2020 Season 3 Patch 4 released on a Thursday. And it includes a number of changes for the new damage model.
Most of the updates are minor tweaks and improvements including how car damage is displayed on opponent cars and to prevent more unusual behaviour when wheels and suspension is damaged.
The rest of the iRacing 2020 Season 3 Patch 4 mainly focuses on individual car changes, so you’ll need to see if your choice for any current series are affected. Classes which see updates include all the NASCAR series, ARCA, various GT3 cars and the Formula Renault 3.5

New Damage Model
– Adjustments have been made to improve the New Damage Model on opponent cars, so that it more quickly matches the actual state recorded by the server.
– – Most damage states received from the server are now applied to opponent cars immediately.
– – The exception to this are damage states that would reattach wheels or car parts.
– – – In these cases, the damage state change can be delayed. The reattachment of wheels or car parts will be delayed if the force involved in breaking the part was above a threshold. There is a low and a high threshold with separate delay times. More severe impacts will cause a longer delay, minor impacts will have no delay.
– Fixed an issue where some car-on-car contacts were not creating incidents correctly.
– Fixed an issue where Replays featuring cars that had the New Damage Model at the time and have since been reverted were not loading correctly.
– – Now, whenever loading a Replay, the Simulator will always use the New Damage Model car if that car had ever used it before.
– The allowable hyper-extended distance for the front wheels on all stockcars has been reduced to prevent wheels popping through the hood.
– The allowable hyper-extended distance for the wheels on all open-wheeled cars has been reduced to prevent some odd flipping behavior.
– Hyper-extended suspension will now be reset when a vehicle with this issue enters a pit stall.
– This reset, and possible car hop, should only trigger when there is a hyper extended wheel.
