User blog:Mr Procrastinator/On-track vs Partial Off-track Braking Test

With the Version 4.2 Update, many people noted that they couldn't match their lap times from before the update. LussoBerlinetta commented that there is a difference in braking distance when two wheels are off-track compared to all four wheels on-track.

Using the BMW M3 GT2 ALMS with all the R$ upgrades and driving on the Indianapolis Motor Speedway - Speedway course, I tested the time it would take to go from 0 - 250 km/h and then back to 0 km/h.



Acceleration was unchanged in both tests but braking clearly suffers with two wheels off-track. With all four wheels on-track, deceleration was approximately 1.2 g (11.9 m/s). With two wheels off-track, deceleration dropped to approximately 0.8 g (8.0 m/s). Deceleration was linear in both cases.

In the case of the BMW M3 GT2 ALMS, it seems that players are punished for braking with two wheels off-track by reducing braking deceleration by around 33%.
