Edit: This set is now prettymuch obselete. Similar but better items can be found in Juice's WayTooManyTransitions set. The items in Juice's set are much smoother, and therefore nicer to drive on, while this set has 'black-platform' grip

These still have a very marginal use-case, they can be used to go from the grid to half a block up or vice-versa. But generally speaking the ones found in WTMT are much more useful

A set of halfbanked slope to banked blocks. This set includes both starights and 2x2 turns in all surfaces, and everything is double-sided.

This set is essentially an edit of Rxelux's 'PlatformExtensions4' set.
