Quick question about 4-wheel steering

You either go with RWS that turns in the opposite direction of the front wheels, resulting in a smaller turning radius but instability at high speeds, passive RWS that turns in the same direction as the front wheels under load (as seen in ) which results in better high speed stability but gives you no improvement in turning radius, or you go with a complicated computer-controlled system that turns in the opposite direction of the front wheels at low speeds and turns in the same direction at high speeds.
First would be a fair bit of work and instability at speed doesn't seem like something you'd want, second would be the easiest but has the smallest benefit, third would be very hard to DIY.

So somebody using the first system would have to have absolute 100% confidence in their skills as a driver in order to take a sharp turn at a hundred miles an hour. The second system would be more forgiving and easier to use but provide less benefit.

Thanks. I think I got it now.

I already told you no, 4 wheel steering is not an aftermarket product nor would it work on a solid axle.

Just don't include it because it's not at all something a practical street racer would use. It only works on independent rear suspension. Not on suspension the Olds has.

This, the first and third type require some form of independent suspension and the passive rear steering/under-load cornering stuff only works on complicated multi-link setups or semi-trailing arms.

Buick GS, 1970.

What I'm hearing is 'rebuild the entire suspension then add ridiculous over-engineered steering system that keeps the car from turning, as one person in my last thread put it, "like a battleship".

BUT you don't need to do anything retarded like 4WS to make a car handle. Just say "fully modernized aftermarket suspension." This kit, for example, replaces every front suspension component and every rear control arm. The axle is the only thing that's kept as that's what fits under the rear. Makes the car handle extremely well when paired with good tuning of the components and grippy tires.

Thanks.

I have some other questions, but they involve slightly more exotic Automotive Technologies that I don't think anyone on this board is familiar with. Unless someone here knows a lot about injection systems, fuel to air ratios, rotary electrical generators, and separating hydrogen from distilled water via electrolysis.

I knew it would not be a commercially available aftermarket product. It is something that the character in the story I am writing would have had to construct and machine himself.

I know a little about most of the things you mentioned. Most people here are familiar with fuel injection systems and air/fuel ratios too.

A friend of mine was telling me a while back about a system he wanted to set up in his Ford F-150 that would use electrolysis to separate hydrogen out of distilled water. It could use any kind of water, but distilled water worked the best and left fewer residual elements in the container. He intended to then pump the hydrogen into the engine. He wanted to set up a stroke pattern for each piston so that the first stroke would be an exhaust stroke, then conventional fuel, then an exhaust stroke, then a small pure hydrogen explosion. I wanted to know the feasibility of such a design. He insisted it would require a lot more electricity than a regular alternator could produce and intended to convert the entire drive train underneath his truck into an electrical turbine. This is some straight-up homemade Frankenstein Automotive Mad Science, but from what I can tell on paper it seems feasible.
