- Sim racers practising braking with a pedal setup
- Worth noticing
- The site labels grip figures as estimates until measured from telemetry, currently identified as iRacing telemetry.
Field notes
The trainer asks users to follow a scrolling brake curve with their own pedals, progressing from simple holds to trail braking and scoring pressure and timing. The planner's guides cover 35 cars across four classes and 74 road and street circuits drawn from iRacing lists. RaceBoost marks grip values as estimates until measured from telemetry, identifying iRacing as the source for now; the desktop app and its in-game overlay are presented as future additions.
