This is a Nascar item set with modified Randsteins and real-life track visuals.

The track is as wide as vanilla blocks between the Randsteins. You can choose to place Randsteins that are more consistent than vanilla Randsteins, grass, or a close wall beside the track as a track limit. Different walls can be placed on the basic road items: close or far walls, with or without catch fences. Pit lanes can also be placed in European and American styles. Road courses can be emulated by placing far walls. Street circuits can be emulated by placing close walls, and speedways can be emulated by placing a close wall on one side and a far wall on the other.

The item set includes unique double curves: two 45° turns with a short straight in between.

This item set also includes half-banked to flat transitions, with the flat part on a lower level than the half-banked part.

In the Misc folder, there are several things worth explaining:

• The "Pitlane" folder contains pit lane blocks in European and American styles. They are meant to be placed on blocks with a close catch fence or a close wall from the Straights folder. The Pitlane Entry block is meant to be placed before and after the pit lane instead of close wall or catch fence blocks.
• The "Randstein Starts" are meant to be placed before and after Randsteine. The Randsteine and the grass behind them are slightly higher than the ground, so placing these blocks prevents bugs while driving.
• The "Transition to Vanilla" folder contains a straight block that lowers exactly to the level of vanilla road blocks.
• The "Base Endplates" folder contains visual endplates for blocks that are placed non-coherently in the air. They are not integrated into every item to prevent bugs and to reduce file size.
• The "Pillars" folder contains support pillars that can be placed below the blocks to connect them to the ground.

Regarding the 1MB size limit for custom items: be careful with setup variety when using different wall and Randstein layouts. The basic road blocks are unlikely to cause file size issues.
