Changelog/Patch Notes
--------------------------------------------------------------------------------------------------
One of the main complaints about Vanilla Carbon, is that many of the Tier 3 cars are just kind of terrible.
This mod aims to amend that.

Consider the overall performance and or handling level to be MW+.
MW Performance was used as a baseline, adjustments were then made from there.
The mod aims to still keep the distinct feel of each car class and each individual car.
To put it simply, in order for things to be viable against the Vanilla Corvette, some level of power-creep is necessary.
The Corvette and Viper are still just as good as you remember, but now you wont feel so limited in terms of Tier 3 car selection.

Broad changes compared to the vanilla game:
- Transmission upgrades no longer harm acceleration (GEAR_EFFICIENCY values are set to 1).
- Induction upgrades no longer harm certain stats, such as power output or spool time up.
- Exotics no longer have painful amounts of understeer. Their MW power output is used as a baseline and adjusted from there.
- Tuners are no longer painfully slow. Their MW power output is used as a baseline and adjusted from there.
- Certain muscle cars have slightly more grip and downforce, though their main focus is generally raw power output.

Not a fan of the changes?
You can always uninstall/revert to vanilla values at any time.
Uninstall Scripts for each game installation type are also included.
These are located in the "Uninstall" folder and also support VltEd and OGVI.

Some optional scripts for both installers have also been included.
These include:

- More realistic engine sound for Skyline GTR R-34 when upgraded (basically a higher rpm version of the stock exhaust audio)
- M3 GTR (Race) Has it's higher pitched engine note from MW
- Infiniti G35 has a slightly louder engine when upgraded
- Change engineaudio for upgraded Plymouth Hemi Cuda from dodg_polara to plym_cuda_a
- Give the Corvette C6 and C6.R their higher pitched engine note from MW (Improvement Mod v2 Only)
- Give the Infiniti G35 its completely vanilla stats, but make it a Tier 2 Car.
- Make the Nissan 240sx a Tier 3 Car with MW-esque performance upgrades (Fun)
- SLR Supercharged Engineaudio when Upgraded

Once again, these are entirely optional.
If you don't want them, just keep them un-checked when installing.
These can also be reverted at any time.
--------------------------------------------------------------------------------------------------
Was designed for/completely compatible with:

- Vanilla NFSC
- Vanilla NFSC with upgradeable Bonus Cars (Does not add them, only accounts for them)
- Vanilla NFSC, Add Upgradeable Bonus Cars.
- Improvement Mod v2 by 379Felipe.
- Ultimate Mod by Ratt.

Was not 100% designed for, but can technically be installed on-top of: (may or may not get some errors, idk?)

- Any kind of Modpack

- Pretty much anything that supports VltEd or OGVI really. At the very least, in pretty much any build of Carbon, all of the non-bonus cars WILL get their stated changes.

*If you're unsure which one to select, Vanilla with Upgradeable Bonus Cars is probably the safest option.

CANNOT be Installed on-top of:

- Carbon Battle Royale.

MW shiftpattern Port Install Instructions [Attribulator + OGVI only]

This is only required for Improvement Mod v2, as the C6.R uses its shiftpattern from MW.

If you're not an Improvement Mod v2 user, you can skip step entirely.

If you've already installed MW shiftpattern Port, you wont need to install it again,
you can skip this step.

I've kept it as a separate Installer, so you don't get an
annoying error message saying "add_node failed because collection already exists" every time you update it.

An Un-Installer with instructions is also Included.

1. Open up OGVI

2. Press File>Import ModScript and import "MW shiftpattern Port Installer [OGVI]"

3. Select "Install"

4. Press "Import"

@Citizen2007.
I've played with Ultimate Mod + Balancing Update + Pursuit Challenges and I've never had that issue.
The Mod doesn't change any of the presets for the corvette z06 so idk what would cause that issue.
Sorry I'm not able to help on this one.

@ElNico It's been a while but nevertheless I have a question regarding the installation process, I tried the mod with Ultimate Mod and your Pursuit Challenges mod a while ago and I decided to add Extend Customization to the mix and I'm not sure if combining that mod with this mod causes this issue, but the issue is that in the intro chase with Cross his Z06 doesn't spawn just the wheels, after the NIS scene the wheels disappear. (Install order: 1. Ultimate, 2. EC, 3. Car Balancing Mod).
