2. Changelog (from original):-

Arguably the best made car we’ve ever used, so most of the changes are oriented towards league use.

  1. Softer/gentler over kerbs (Assetto’s biggest bug-bear)
  2. Slightly less reactive tyre temperature fluctuations
  3. Marginally sharper turn-in
  4. Brakes beefed-up a bit so they will lock-up now
  5. Equally, the rears will break under traction, but still easy to control
  6. Slightly improved tyre wear
  7. Drag curves revamped to bring medium/lower wings more into play
  8. Pit times all reduced
  9. Raised underside collider so it’s easier to steer on grass and get out of gravel
  10. Tyre compounds colours remodelled to make use of TyresFX.
