Ok, a few cars out there have passive rear steering to help with cornering (some active too), it seems a good idea at first, but I was wondering why more cars aren't fitted with it.

If it's any good, would it be technically feasible to build a rear beam/subframe that would work like that for a cossie/rst ?

not very good for high speeds ive heard

got mate who has had loads of 300zx with it but he replaces them so the rear end isnt sterring

but may be wrong

lol

 

used to work for nissan for over 10 years and its a very good system, especially at high speeds , thats what hicas was made for !!

 

If your talking about 4ws like on the honda prelude it works very well drove a mates on the weekend, also helps the cars handling quite alot he was on par with a few gt4s on a handling circuit so it must do somthing,

My Mitsubishi has 2 steering racks - one for the front and 1 for the rear.

It is fantastic round corners and stable at speed

 

My tractor has 4ws

 

and i bet its hydrostatic as well !!

 

Yup, Great till you get to a hill!

 

3000GT is it ?

 

I think that any "home made" system is going to be difficult to get working 100% ALL the time. You'll need loads of extra sensors for steering input, vehicle speed, throttle position, yaw rate etc etc Mucho headaches!

A Passive system where the various parts twist torsionally would probably be a safer bet. On a permanently RWD car, I can't imagine theres a need. A better suspension geo will do 90% of what you're hoping to achieve. A better turn in, and a more stable rear when accelerating out of a corner. Something Im led to believe Cossies arent very good at.

On a FWD car something like a RST will need a complete assembly. Maybe retro fitting a Pug 306 trailing arm will do the job?

Good thread btw. Far too many on here are about straight lines

 

Thanks Rich w

I don't think a retrofit active system would be possible unless the car was built with it, unless you have loads of money to throw at the problem/solution.

Assuming you have the 90% you are trying to achieve already through better suspension geometry, would the extra 10% be worth it ?

Anyone from Zoo reading this ?

 

Go indepenent on the rear

and look at new products

 

These appear to be front wheel drive mainly. Does independent mean no anti roll bar anymore ?

Sorry, don't know much about suspension setups

 

Porsche used to bung in rear-steering for free on their older 911s
