    Anyone ever thought of or tried experimenting with a rear steer car? (Like a forklift) i ask because i was thinking it would somewhat make sense...youd need far less steering input to keep a car agaist the rail and the steering wheels would have far more weight on them meaning the steering force wheel would bounce much less...just a thought

    I don't think it would fair very well. In a front steer car with the typical 1/16th" shaved off of the body at the steer wheel side and the rear wheels canted 3 deg said rear wheels are centered to the track's center guide rail and never touch it.....the front steer wheel is the only wheel that contacts the rail. In your proposed setup it seems that both the front and rear wheel would touch the rail. If we was to reverse the standard rail runner setup with the front wheels being canted at 3 deg and 1/16th" shaved off the body at the rear wheel steer location that still leaves us with possibly having our one raised wheel on the other rear axle where all of our weight is and I'm not sure that the rear would be stable with only one wheel on the track with all that weight. Just my thoughts......

    Good point! I had overlooked that the front wheel as well as the rear steer wheel would be pinned on the rail as well...that would add a whole lot of friction

    Sounds like a fun project to test out if you reverse everything. lol

    The best advice i can give a new guy is learn to build a 3 wheel rail runner to top speed then monkey with ideas like this later

    Here’s another thought... look at the pros in the 3 leagues... league racing has been around a while now and the real successful pro racers do everything humanly possible to shave every ten-thousandth they possibly can off their time. It’s safe to say, if rear steer had even the slightest chance to work, they’d be doing it. Just my opinion mind you, but these guys do what works, and what works best.
    Fun to go out of the box of course and we’d all enjoy watching the R&D and results, I just don’t think it will result in any speed records.
    Again, just an opinion.

    Now you got me curious lol.....I've drilled a block reverse rail runner style and gonna build a experimental car to test my hypotheses lol

    Not the smartest cat in the bag here....but it seems to me that building a rear steer pits all the mechanical frictional forces to to required by physics to the heaviest aspect of a free falling object this destabilizing the nose increasing the possibility of unnecessary bang which in turn applies additional unrequired drag. The whole point of rail running to my understanding is to remove all friction and increase stability....just saying

    Hmmm i thought it was just to force the car into a straight path to the finish line and cut out the extra distance caused by weaving back and forth
