I have a 92 lude and was thinking of doing a 4 wheel steering conversion.
Any of you guys done this?
If so what parts would I need to do this conversion?

Post yo pics!! Let's see 'em!!

 

I have the steps right here. Only one step;

Sell your car and buy a 4WS Prelude.

Trust me, it is A LOT of work and will require getting, and wiring many sensors. It's not worth it.

I have 4WS and I have a few issues as it is.

 

yeah i hear of more people having problems with the 4ws than people that like it

Most of the people having issues with it are 92 owners. I am one of them. It works 90% of the time.

I LOVE it!!! It makes driving in tight spaces a lot easier. Plus, da chicks get wet when day see mah rear wheelZ turnin.

 

Lots of work when your car has it...I could only imagine converting a non-4WS car to a 4WS car. True dat AndyD, errrbody like the rear wheels turnin'. Its real nice parallel parking with it though, but more of a hassel than a luxury overall

 

It's a real asset on a track ("road track" ?? not a drag strip, not an oval, a real track..)
Makes tight turns a breeze
and makes drifting easy

 

I have a 92 and I have never had one problem with it except for bumping the occasional curb and shutting the system down. That is more my problem than the cars problem. I would say it works 100% of the time for me.

 

I have a 92 4WS and absolutely love it. It is easy to maneuver at low speeds, feels amazing at high speeds, and is just freakin amazing when the rear end brakes loose, so controled, not to mention the bling factor. i have not had a problem so far. I would highly recommend getting by buying a car with 4WS. I cant even imagine how much crap would involved in converting TO 4WS. Good luck finding one as there arent many out there.

 

I actually havn't had the chance of riding in one yet. I guess it would be a pain to convert all the parts, sensors, etc. <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by AndyD &raquo;</TD></TR><TR><TD CLASS="quote">

AndyD or any of you other guys got any pics of the wheelz a turnin? POST 'EM!!!

It sounds like most of you guys enjoy it, except for "jz". I know I sure would!!

I ride a 4WS lude, and bring it to road races. It's an asset, not a liability.. The car feels great and 4WS kills a good part of understeer. Even when pushed to the limits the car is still very controllable.
Of course one must never run a car with the 4WS light on.. in that case either fix it or unplug it.
Never had any problem as well, apart from blocking a wheel against a curb once or twice..

Retrofitting the system would involve:
* wiring the speed sensor
* wiring the steering wheel sensor (this one seems tricky without the proper steering wheel ??)
* wiring the 4 wheel sensors
* wiring the 2 auxiliary rear sensors
* fitting then wiring the 4WS ECU
* lots of work on the rear part - fitting and wiring actuators, rods, etc.. Not sure how it is different from a 2WS but i guess there are some link rods involved as well.

Thanks for the info. It shouldn't be too difficult. Anything is possible.

I wonder what else needs to be done on the rear part?

 

Yeah anything is possible when you have a never ending wallet...dude if you want 4WS by a lude with it already...I bought my 4WS lude for 1800, you will probably spend that on just parts if you can even find them.

 

tru. appreciate it.

 

Yeah, i have ridden in a 4WS Lude, MINE. Read thpost and the sig. When i say brake loose i dont mean out of control. You know what RWD cars feel like when they break the rear end loose? Thats what i meant, except even better.

 

which way do they turn?? the same as front or oppisite like the SUV's that have it?

 

They turn opposite so the turn radius is smaller.

If they faced the same direction, you'd be drift driving and have a larger turn radius.

The 4WS ECU (the one behind rear seats) decides the way and the amount they turn.
Low speed, or high steering wheel angle = opposite direction
High speed, or low steering wheel angle = same direction
there are other parameters as well (current angle of each wheel, speed of steering wheel turning)

Indeed it needs to be tamed, when you first drive a 4WS you feel like the end is going, though it's not, it's following the front ! Very weird at first, but after a few lapping sessions, it's like a drug Coming at high speed in tight corners you can even force the car into a real drift, like a RWD ! Adjust well the rear shocks or else the rear end will go away during a drift. Too hard a setting = unstable.

As for retrofitting a 4WS, apart from the wiring nightmare (good luck on this one.. check wiring schematics in your Helms), actuators and the ECU are über-expensive. Maybe from a scrapyard.. if they're in good condition.

Under 18mph.....they turn in the opposite direction as the front wheels. Above 18mph they turn the same direct....but not as significantly.

On the highway, you don't notice a difference. However, in the parking lots and tight cornering, the difference is VERY noticeable.

As far as road racing....I have used my car for 3 track events so far with my OEM 168K miles suspension. The car handled GREAT!!! VERY stable. The car felt planted the whole time. In fact, my instructor was VERY impressed how well my car handled for the mileage.

Now, I wouldn't take my car on the track when my 4WS light comes on. That is where I have a problem with the car. The rear wheels do not lock.

 

ophdehEEzY's lude is one of my favorites with 4ws.

Did you try the 4WS debugging procedures ? Those in the Helms.. at least getting the ECU error codes ?
There's an auto-centring spring that's supposed to keep the rear wheels straight when the 4WS is offline. I'm not sure the spring is too strong - it may be just a "limp system" so you can get your car back to repair the system ?
