Check out the track building thread .
Its in the dirt oval section .
There may be some discussion on asphalt and layouts .
I like a paper clip style with uphill into 1&2 and slightly down hill into 3&4 .
With good banking in the turns and back strech , flat in front strech .
That's pretty small 440 LF, it depends on what your looking for, If you want momentum and most speed it will have to be pretty much a circle, the more you paper clip it the out of the throttle it will be.
