[DATA REPLACEMENT] Physics rework for Marcas cars 1.5

NOTE: THIS MOD ONLY CONTAINS REPLACEMENT DATA.ACD FILES AND IS NOT A COMPLETE CAR. THE BASE CAR MUST BE DOWNLOADED BEFORE APPLYING THIS DATA PACK; LINK FOR THE ORIGINAL CARS PROVIDED IN THE README FILE.

This project has been my first deep dive into how the physics data for cars in Assetto Corsa work; the original cars in question were added to Assetto Corsa by Malagoli, but this data pack requires the graphical revisions done by GTPlanet user DBag.

These original cars were fine but had several issues. Below is a list of changes that I have made for these cars:

• Increased weight with driver from 1050kg to 1235kg
• Replaced 90's slicks with modern slicks
  • Increased tyre tread width from 230mm to 285mm
  • lowered tyre profile from 650mm to 645mm
• Overhauled engine with 13% torque loss calculation:
  • Power now peaks at 244BHP @ 6800 RPM
  • Torque now peaks at 276NM @4900 RPM
  • Engine is now limited to 7100 RPM with damage starting at 7200 RPM
• Dashboard instruments adjusted for new engine data.
• Fuel tank enlarged from 60 Litres to 70 Litres
  • Starting fuel now set at 35 Litres
• Rear wing angle can now be adjusted between 10 and 30 degrees
  • Default wing angle set at 20 degrees
• Added adjustable suspension:
  • Front Anti-Roll Bars can now be set between 20000nm and 70000nm
    • Default Front anti-roll bars set at 60000nm
  • Rear Anti-Roll Bars can now be set between 20000nm and 220000nm
    • Default Rear anti-roll bars set at 30000nm
  • Front ride height now ranges between 50 to 60 mm
    • Default front ride height set at 55mm
  • Rear ride height now ranges between 55mm to 75mm
    • Default front ride height set at 65mm
  • Front Camber angle now ranges between -5 and -3.5 degrees
    • Default front camber set at -4.5 degrees
  • Rear Camber angle now ranges between -4 and -2.5 degrees
    • Default rear camber set at -3 degrees
  • Front Packers can now be set between 0 and 50mm
    • Default front packers set at 10mm
  • Rear Packers can now be set between 0 and 60mm
    • Default rear packers set at 20mm
  • Front Toe Out Angle now ranges between 1.5 degrees and -1.5 degrees
    • Default Front Toe Out set at .75 degrees
  • Rear Toe Out Angle now fixed at -1.66 degrees
  • Front Spring rate set at 300000nm
  • Rear Spring rate set at 80000nm
  • Rear hub mass set at 44kg

Known issues:

• Tuning menu settings offset against in-game Camber angles by approximately -0.5 degrees. (Tested on Gary Paterson's sh*ttrack due to level surface all round. Camber ranges have been adjusted to compensate until a proper fix is found)

Below is a short test run I did with the car around Interlagos in the car's default setup. The skin used is the 2014 Thiago Marques livery for the Chevrolet Cruze in mr.t.'s Marcas skins pack, while the sounds are from Fonsecker's MX-5 Soundbank from part 3 of his sound effects pack:
