2020 Chevrolet Corvette C8 Physics Update

2020 Chevrolet Corvette C8 Physics Update 1.5

So this is probably the biggest physics overhaul since v1.0, I realized there were a few issues from my original calculations to come up with the base mass and well, here we are. The car is heavier so it will probably be slower by a few tenths a lap if you're driving at 10/10ths, but I've learned a lot about the tire modeling and this should be much more accurate to how the real car behaves. The car is even less twitchy and much easier to drive now (like the real car) and you can get on the accelerator much earlier coming out of a corner. I made some other graphical updates but this one was mostly a physics update, and while it's slower the car is still fast and much easier to drive up to about 9.5/10ths. I use Laguna Seca for my testing and compared with Randy Pobst's time for MT of 1:37.83 my absolute best was a 1:37.77, with a 1:37.52 potential:

Anyway, here's the list of updates. Have fun!

2/20/2021
Added mirror texture to each skins folder to stop CSP glitches showing red/blue shades in mirror

2/22/2021
Updated tyres.ini to add tyre wear and performance curves (thank you to Verdes Garage on youtube for pointing this out!), fixed swapped dx/dy values in rear tires

2/23/2021
Updated car.ini to fix weight (was too light, I calculated the driver/fuel weight difference incorrectly when initially setting it up...)

2/24/2021
Further tweaks to ext_config.ini (no more interior mirror finish!)
Lowered ABS slip ratio in electronics.ini

2/25/2021
Updated brakes.ini to match higher mass
Further tweaks to ABS and TCS in electronics.ini
Lowered blinking frequency for pit lights in lights.ini

2/26/2021
Final graphical updates to suspensions.ini

2/27/2021
Updates to tyres.ini to adjust grip on tire flex to reflect Michelin PS4S over Michelin PSS

I'm certainly no artist but with a bit of help from alekabul (thanks again!) I hope the car looks a bit better and warrants an update for those using CSP, and even should be more accurate for non-CSP users. No physics have been changed so shouldn't affect any online play, but my goal with this was to get the 2021 colors accurate since seeing them for the first time. It's not perfect but I hope you all enjoy it! :)

2/15/2021 Updates:
Added CSP elements to paint and interior with significant help from alekabul (thank you!!)
Added custom caliper colors (and very easy to further customize if you want, as these are just .png files)
Updated Accelerate Yellow to be more accurate to the real life color
Corrected poor textures for "morello" interior color
So being lucky enough to drive a couple of C8s both on the road and briefly on a track I was honestly expecting to make a lot of changes to the car, but I'm very happy to say I think the actual physics for this is pretty close; at least as close as I can get with my limited ability. So I wanted to release this update mostly to address some cosmetic fixes and to include the updated colors for the 2021 Corvette (Red Mist Tintcoat and Silver Flar), including some extra color schemes. I haven't changed any of the driving physics from the last update, but I did update the fuel consumption to be more realistic, so here's the specifics:

-Updated dash_cam.ini to improve view and include instruments
-Updated digital_instruments.ini to correct RPM LEDs for color and function per real car
-Updated car.ini and fuel_cons.ini to make fuel consumption more accurate
-Added template for secondary paints and updated skins
-Added blank damage .dds files to skins, as the included ones in the .kn5 don't line up with the car and it was driving me crazy having glossy stripes while the rest of the car turns matte. If I can figure out a way to actually make the damage/dust look good I'll post a hotfix with those

Cheers!

The collider.kn5 in the original mod was from a DLC which was what was probably making the car undriveable for anyone who didn't have the "Tripl3 Pack". Updated the collider.kn5, should work for anyone without DLC now!
Added missing files from last update
Relabeled as v1.12 for Content Manager users

Updated ai.ini to match corrected RPM limit. AI worked fine for me prior but just in case it was becoming an issue for anyone else, figured it can't hurt
Corrected name in car.ini so it's more legible
Updated sounds.ini for outroof so that there's more wind noise (this is the only data based difference between the two versions)
Added Chevrolet logo.png so the right logo loads (no fake Ferrari badges here!)
Corrected suspension geometry to fix prior error

Also added a link to download original mod in Read_me.txt
