What is the radius of bend used on the NPWDRL at the transition?

What is the radius of bend used on the NPWDRL at the transition? Is it the Best track as they list in their specs? A 4 ft radius?
When I watch the race videos it looks like a much sharper transition. I'm making a car with a low COG and I am afraid I'll drag bottom in the transition.
Thanks,

As long as you are ~1/8" above the surface (the center guide is 1/4" high), you'll be fine.

I've never seen the track, but I can't imagine any custom work being done there. It is a Best Track and I'm 99.9999% sure it's whatever came from the factory.
