Class C sits at Performance Index 401–500. You get a clear step up from D: more upgrade headroom, still enough mass and grip limits that setup choices show up immediately in lap times.

C-class cars show up across mid-early festival playlist events and mixed road/street playlists. Tuners usually chase a balance between acceleration out of slow corners and stability when the car unsettles over crests.

Watch for tunes that call out understeer on entry versus mid-corner push. A C-class road race setup that rotates cleanly is more useful than a high-power drag conversion if you are racing a full circuit.

Use the filters below to narrow by discipline, then open a tune page for the share code and any tuner notes. Empty results mean the community has not filled this bracket yet — publish one if you have a car that fits.
