Cup Physics
- Richmond package: First attempt to simulate the 2015 rule changes. The engine is meant to simulate the tapered spacer. It produces about 530 ft-lbs of torque at 7000 RPM and a little over 725 hp. Redline is now 9000 RPM. The rear spoiler height has been lowered and other aerodynamic changes have been made to balance the car. We also fixed a previous oversight that did not include the weight of the driver.

Truck Physics
- Kentucky package
- Cold brakes now stop like the Cup car (should lock up in pit box)
Saturday 1/17/2015 Tracks
Added Richmond

Sounds
Reduction from 90MB to 40MB by eliminating duplicate and unused sounds files. Restored original engine sounds to ARCA car (alternate engine may be re-added as an optional add-on). Interior skid sound is a lower pitch but higher volume (old skid vs. new skid).

Cup Physics
Added Richmond package and default setup

Truck Physics
Adjusted Richmond tire/engine heat and default setup

Models
Higher resolution mirror for ARCA and Truck (now same as Cup). Seat and mirror default position for each vehicle standardized so that the same player preference should position the seat and mirror similarly when moving from one vehicle to another (eliminating the need to adjust the seat and mirror when changing vehicles)
