rFactor 2 – Mak-Corp Group C mod V0.80 Released

The Mak-Corp modding team have released V0.80 of their 1991 Group C mod for rFactor 2.

The 1991 Group C Mod includes the Mazda 787B and the Porsche 962C in the latest version of the mod for rFactor 2. Featuring unique realistic physics for each vehicle as well as different tire compounds, this is your chance to get behind two of the most iconic cars in the history of Group C racing.

This new update introduces improvements and fixes concerning the physics of both the Porsche 962C and the Mazda 787B Group C cars. For the creative community members Mak-Corp will release new Paint Templates this Sunday.

The download archive file includes documentation for both cars explaining some of their features and upgrades.




v0.80 Changelog:

Porsche 962C

  • ADDED: New Torque Curve for each engine. More Torque at low RPM and power peak at lower RPM to make the engines more “Porsche”
  • CHANGED: Engines use a bit less fuel
  • CHANGED: Small increase on brake power
  • CHANGED: Headlight flicker reduced but remains for now as the only way to stop it is to increase near cam clip distance which when changed to fix flickering, clips the cockpit, so not useable.
  • FIXED: Manual clutch torque

Mazda 787B

  • CHANGED: Small physics adjustments
  • CHANGED: Drag adjustment
  • CHANGED: Small decrease on brake power
  • CHANGED: Downshift sound modified/removed when using manual clutch
