I might be getting a lood, just wondering is the Prelude 4 wheels steering is any good? I mean does it actually help with performance\cornering?

 

it only helps with parking lot manuvers. At road-racing speeds or even in autocross, the tires don't turn in the opposite direction any more - they actually turn in the same direction. This would hurt your high speed cornering ability.

It also is kinda heavy I think.

 

what year prelude are you looking at? the 88-91 preludes have manual 4ws, not electric. i never had any problems with my 89.

 

i autocross on the 4ws (i have an 89).

It definitely makes a difference. Even on sweepers. Just at the last event there was a FAST sweeper, and the only thing pointing me through the corner was the rear wheels (well, not really, but i could tell that they were helping point the car in the right direction. It's kind of an odd feeling. Kinda like the car is oversteering, but it's not)

it's not really heavy. i'd say the whole system <50lbs. After all, it's just a small box and a small diameter shaft that goes from the steering rack to the rear. Everything else is on the 2ws cars too.

and it's GREAT for parking lot maneuvers!!

 

Anyone know how the skyline's 4WS works? I'm assuming it's pretty advanced.

 

4WS makes a difference. Most anyone that actually races a 4ws car rather than just pimpin' around town will tell you that. The problem is whether the extra small benefit offsets the added weight. Probably not. That is the main reason you never saw very many 4ws cars in road racing. Most road racing series such as USTCC make 4ws cars carry an extra weight penalty of about 50 lbs. I did track events in my 90 Prelude and it made a difference. And in the 3rd gen the speed of the car has absolutely nothing to do with the rear wheel steering angle. Nada. I can't speak for the 4th gen system though. Since it is electronic it could be speed dependent. So basically, 4WS helps cornering and hurts straight line speed.

chrisb knows his stuff, so, i agree with him, plus i loved HP.com

 

Under 18mph the rear wheels countersteer, over 18mph when you first turn the wheel slightly the rears turn in the same direction(to assist in lane changing), but when you turn the steering wheel more the wheels recenter. And if you turn past that they start to countersteer. I own a 92 4WS. what i like about it is that it gets rid of some of the understeer that FWD is so well known for. It actually feels like an controlled oversteer through a hard corner, but without the tires loosing grip

 

my 1992 4ws prelude si is for sale.
