I have a few idea make new the brick for vehicle spawn. This allow you can spawn of your vehicle on the new brick.
These are brick start race line for speedkart.
Soon coming new the model will look like this
New Development (SpeedKart Spawn Brick)
Plan future make:
HeliPad - postpose, not long.
Parking - Postpose (sorry)
Printable
If you have any idea and suggest, please comment here, I will make more the model!
