Can anyone please explain the "Rail Rider" Technique

it is often faster to create a "rail rider" on purpose in order for the car to get rid of the "wiggles". you can achieve this by bending the front dominant axle (slightly), put a mark on the axle head with a sharpie at 12o'clock and start rotating the axle until you find the car's full potential. Mark off a straight line of about 4' and note what the car does at each adjustment. It is said that you want ur car to pull to the rail(line) about 2" over the 4' distance. You will be surprised at just how accurately you can steer your car wherever you want it to go. Rotating ur axle slightly(1mm or so) will make a big difference. I have just started to do this and haven't mastered it yet. it can be tedious and time consuming. there may be other methods also. good luck

Rail riding is based on the theory that no matter how strait a car tracks on a level surface, over the course of a 42' track it will hit the center rail occasionally. Each time it does, the impact will cause a lot of friction and have a dramatic negative affect on the speed of the car. With a properly aligned rail rider, the car come into contact with the rail once and stays in contact with the rail through the finish. In effect the rail acts as a guide so that the car truly runs straight (straight along the rail that is).
The disciples of rail riding (myself among them) say that the friction caused by the car coming into contact and staying in contact with the center rail is considerably less than the friction that results from the car banging into the center rail every so often.
Hope that helps.

This also keeps your raised wheel from hitting the rail. If it does hit the rail energy is robbed from the car in order to turn the static wheel. Energy robbed will slow down the car.
In essence your raised wheel becomes a brake when it hits the rail.

Would it be better to run a slight toe in and zero camber?

It'd be nice if there was a way to RR without bending all of your nails.

It is pretty easy to bend axles with the tools from Derby Worx! If you need help, send me PM and I can walk you through the process. Pretty easy and fun!
