So I asked a guy on the road while driving, coming to a light about the "rear active steer", and i asked him about how he liked it. He said bassically it doesnt do anything, and that it was not worth any extra money. He was driving a m45. The car looked good, but for all the 03 to 05 coupe drivers who felt the missed out, i dont think we did, because this guy said, it wasnt really good, now i ask all you 06 coupe guys honestly do you feel it? Or is it more of something in your head? im not bashing the system im just saying that i dont hink it could be that good? if anything it will lead to problems? Im not bashing just giving my .2.

happy holidays everyone. and try to not drive on new years, its always a bad day for accidents and i dont want to see anybody get hurt and possibly ruin there beautiful G's.

 

yeah, this topic has been brought up before

It's a useless part pretty much, waste of money and another thing to break down.

 

The value of any suspension system or part is only as good as the ability of person doing the reviewing to know what's going on. Just because someone who may not know what their suspension is up to say's if valueless doesn't mean that is the case. The FM platform has a awfull lot of bushing compliance built into it. This includes toeing out in the rear suspension under high loads. Thankfully Nismo now has a firmer bushing package to help reduce this.

"The handling and stability of the 2006 G35 coupe is further optimized by an available, new Infiniti Rear Active Steer system. Unlike passive rear steering systems, this design features motor-driven control. This system helps improve the vehicle’s handling performance by adjusting the rear suspension geometry according to steering input and vehicle speed.

The system’s electronic control unit calculates the desired vehicle dynamics from a series of sensors, including vehicle speed and steering angle, and directs the system actuator to change rear geometry by moving both rear suspension lower links. The result is sports car-like agility, combined with luxury stability and ride quality. The Rear Active Steer system was first introduced on the 2006 Infiniti M45 and M35 Sport models. It is available on the 2006 G35 Coupe 6MT models with Premium Package and G35 coupe models with Sport and Premium Packages.

In addition, the Rear Active Steer Package adds an enhanced vehicle-speed-sensitive power steering system with a 15.1:1 steering gear ratio."


Now am I wishing I had the system on my car? No, eventually I'm going to kill off my car's soft oem bushings with either the Nismo bushings or sperical bushings where affordable. But I would like the quicker steering ratio.

 

HMMM, I wonder how the dynamics change if you modify the suspension. I mean, the car activates this based on steering input and vehicle speed...so, if i lowered the car, woulkd the system react the same and to what caliber, if so. I mean, I wouldn't want the car to automatically toe/camber the car way out of spec to the point of danger just because I've screwed with the suspension setup. Not something I'll be dealing with anymore since the car is sold, but I thought that was something to bring to the table. Eat up.

 

The last generation 300zx had this. It made the car unpredictable at higher speeds(track use). Stillen made a suspension part to defeat the rear active steering for track use. In big trucks that need to be able to turn in tight spots, it works good. In sports cars that turn good anyways, it's a bad thing. Don't need it, don't get it.

 

I figured that this option would only be used by a really aggressive driver, pushing the car to the limits (like at the track). For us normal drivers that punch it here and there to enjoy what the car has to offer, it does not matter. If I was buying the car brand new, I'd probably get everything, but right now, I love my Pearl '04 with black leather, a combination you '05 and '06 owners can only dream about. ha ha Take care.

 

Who cares, we got Brembos. hahahahahahahaha!

 

The rear active steering is incredibly beneficial, in my opinion. This isn't one of the old-school hydraulic based systems. This is a fully computer-controlled servo-actuated system allowing much more control of the vehicle dynamics. At very high speeds the system acts to stabilize the vehicle, while at lower speeds it acts to allow faster turn-in and more damped corrections. I've driven G's without the rear active steering and mine, and the difference in steering response is ridiculous! It feels far more maneuverable in slalom-type maneuvers and correcting at the end of the term feels far more stable.

Don't knock it 'till you try it! On paper it is incredibly beneficial from a vehicle dynamics standpoint, and in real life I am very impressed! You '03-'05 owners or '06 owners without rear active steer are just haters! And hell, it's only a $646 option so if you hate it, disable it.

And for those that think 1 degree isn't much... think about your front steering ratio for a minute. It's about 15.6:1 without RAS. How much do you rotate your steering wheel on the freeway in a high speed turn? Less than 5 degrees? Let's say 5 degrees tops for an example. That translates to just 5 / 15.6 = 0.32 degrees! If you could rig up a little electronic steering wheel to just actuate your rear wheels and keep your front wheels straight, the rear active steering you drive your car around on the freeway. :P

- very happy RAS owner who researched it before he bought it

 

That's wonderful. Why don't you tell us WHY your Brembos are better than the stock '06 6MT brakes, other than the fact that they're a cheesy sparkly gold color and more expensive to replace?

 

It's also very useful for emergency maneuvers, like avoiding something on the freeway at 70 mph. That's "aggressive driving" when it matters most.

No thanks on the mustard yellowish white on black.

 

Why? because they look better and don't fade when you are in the canyons playing chicken with your life.

4 piston vs 2 pistons? That's a no brainer.

 

Cheezy?
Here we go again; you could get your **** stomped saying that in front of the right person... Brembo's are proven to be far superior, they just cost more so they were dropped. Stop hating on us Brembo owners, I personally can afford the services and I know I have better brakes than you. Also, I use ceremic pads, no dust, but I didn't really mind cleaning the rims often and still do anyway.

 

Brake fade is a function of the rotor area and the pad. The '05-'06 have similar sized rotors and pads, and I've never seen any fade, so I don't think that's an issue.

But if the '05-'06 calipers are 2 piston compared to the 4 piston brembos, then I see an advantage there at least! I was told by the dealer than the new OEMs were 4 piston as well, but I haven't looked in detail.

 

I think the rear active steering is a nice feature but not worth $ or the added weight. Id rather spend the money on my suspension.

 

Good, the fewer the cars that can outhandle mine on the road, the better!
