What should I do if there is no rail?....

[Pete Buckler]

The two local scout races we run both use Super Track with no center rail. It’s just an edge on both sides keeping the cars on the track.

I’ve been building my cars as rail riders but I’m wondering if there would be a faster option? I would really like to know if anyone has experience with this and how you would build a winning car for this track.

You have to narrow the rear

Keep building them like a rail runner and narrow both sides? Or just the NDFW side because that will keep it from touching?

Zero Experience Here, just my understanding of physics, but I'm assuming:
- Narrow the rear wheel on the DFW side. Lets assume that is your right wheel for this example.
- DFW on right side should steer to the right (outwards) instead of to the center like normal rail riders with a center rail.
- DFW axle on right side should be bent upwards instead of downwards.
- I'm also thinking maybe the DFW could be mounted reverse, to keep the smooth (normally inner) side rubbing on the outer rail on the right, instead of the normally outer part of the wheel with letters that may cause more friction when they rub.
