You MUST have installed ChiefWiggum's 1975 Mod for this to work.
Working together with ChiefWiggum - The new Historic Edition physics. Updated physics from the LE edition,
* Tyre heat adjustments
* Tyre lateral movement adjustments
* Tyre life adjusted
* Engine adjustments, friction/heat engine life duration
* Minor engine braking adjustments made
* Individual physics for each car -
Engine physics, tyre physics (degradation/life span), aero physics, gearing, even down to the pitcrew speed and efficiency for EACH team.
I will be updating and tweaking in the coming weeks, in particular tyre physics.
If anyone has any problems or need help with the mod, drop me a message!!
