161 configurations, mostly racing cars, with some additions. All configurations have been tested for performance and should have no problems with startup.
All configurations are marked with the HPC prefix, with the exception of 7 mock configurations.
The pack has added details such as new transmissions, wheel hubs, several new engines and engine replacements, Bolide parts cut out, and maybe a few more things that I forgot about (a lot added).

In version 1.0.777.01.777.1.1.1.777:
- Added a bunch more configurations (161 in total).
