My first car was steer-by-rope, it's all up from there.

On later models they switched to an electric pump to save space and weight but it was still hydraulic.

Hey .......mine too ......... :thumbsup:

You're welcome.

You're late to the party ........ see above posts ...... ;)

I didn't read the whole thread but I am pretty used to the electric power steering. I found it has good feed back especially compared to other cars out there. As I understand there is a physical connection to the rack and pinion and it is just an electric motor providing the assist as compared to a hydraulic system.

On the street it is totally fine.

The "issue" I have with it is on track days. I guess it gets hot/overheats. In situations where you need to counter steer there seems to be a dead spot. Not sure how to describe it but it feels different and then you feel the "resistance" again.

Sorry for bad explanation but I am accustomed to it now but the feeling is still always weird.

speaking of my Yaris, I can't believe I actually broke the cruise control stalk the other day. I'm going to have to see if CTScott still has some. I'm also crazy enough to wish I could put my wheels from the Yaris on to my BRZ, 6.5 lbs per wheel sounds so much better than 16 or more....

The PS is a feedback loop so when you turn the wheel the computer senses this and gives assist in the direction you are turning. Under high loads where the motor is near max output and you rapidly change directions, I would the motor would still be going the other direction for a split second before reversing. Simracing wheels do this really bad. It’s referred two as backlash so they added a second motor and the two motors are always loaded in opposite directions to avoid the slight lag. Higher sampling rates could also combat this. This is all speculation of course.

I agree. Its one of the great things about the car. At least the 2013 model. I haven't driven any of the newer models so I can't say if it has changed.

Steering hasn't changed. In fact they are now using the exact same parts in the new gen Impreza.

Do you have Volks CE28?

I'm sure Scott can make some more.


6.5 lb. Wheels on the twins would really free up some of that crank up. Haha

It was like that on day one. Still is.

No. I have a lot of those already.

Those 17 steering wheels are brutally slippery when new. Was one of the things that jumped out at me when I test drove one. It is just a poor choice for materials and I am not surprised to hear they don't get better.

I've not once felt my steering wheel was slippery.

Really? Maybe I am just so used to the feel of the pre 17 ones that it seems so bad. I really REALLY did not like it.

My steering wheel is skin polished.

I bought a bottle of leather and vinyl cleaner when i bought my car in 2012. I used it once, lol

I moved from a Schilke 14C2 to a regular 14 just now.. slightly less rounded rim.. and have been playing high Gs consistently for the first time in my life for the past ten minutes. Sometimes it IS about the rim, I guess.

I had a 16 as well. All I notice is the smaller diameter.

It's ok. I'm sure Tcoat got it.

It's a pretty big goof on Toyota's part. I've taken to applying hand lotion (to my hands, not the steering wheel, or any other surface) before driving. That should not be something I need to consider.

If you don't rub it in the skin do you get the hose again?

Maybe the 860 wheel is different.

Typical old man response to being caught re-posting an already posted answer ........ "it was a joke" ....... instead of admitting to a brain fart or having a senior moment ...... :iono:

I hope I never get that far gone ...... :sigh:

I got it!

q50

The Infinity Q50 is a production car with "drive-by-wire" steering.

Damnit doesn't anybody know of a steer by wire production car?
Nobody?

Apparently the FR86Z

Maybe we misunderstood the whole "steer by wire" thing?

My frame of reference is limited but I've read lot of journalists comment that the Twins' compare closely with the Cayman, which many rate as having the best steering out there. I've never not been happy with the steering. Perhaps there is a tad too much assist at low speed.

I think we also need to look at how the weight over the front axle, tire size, and suspension geometry affects forces going to and from the road and back through your body.

Has anyone ever replaced the rack in these cars? Gone full manual steer without any electric or mechanic buffer?

When talking steering feel, what exactly do we mean? I hear this a lot and I've never quite understood. I get loads of vibration and impact harshness through the rim. Going over uneven tarmac and elevation changes seems to affect the force of inputs required to turn the wheel. If I'm going around a bend a high speeds and have a lot of compression on the suspension on one side the steering will fight back a little. Going over wet roads or roads with dirt or sand from construction leaves the wheel feeling completely numb.

Where I will contend it falls short, and seems to be an issue for a lot of electric assist racks, is that you can "outrun" the system if you crank the wheel too fast left to right. Then when the car settles and you make slower inputs, things seem heavier. Maybe the system is stepping in to assist when doing that?

Not really sure what experience some here have had with non assisted steering but it was/is far from all fun and games.


Vehicles that had steering with great road "feedback" that I have drove.

Can go straight for miles. Turns were a bitch.

Is that a 1/2 inch wide crack in the road? OK lets just follow it and see where we go.

You want to turn while sitting still? LOLOLOLOLOLOLOLOLOL suuuuuure.

There is a sensor in the assist unit that detects the difference between steering wheel and column position. A spring-loaded coupling allows for a few degrees of turn either way. It can be felt when cranking the wheel with the engine off.

Hmmm... Stiffening that coupling would decrease the servo response to the faster steering input.

I was sticking with alphabetical to see how close it came to getting all the letters. Just a couple more special editions and they could make it.

Or create a lag.
Or cause the wheel to jerk as it overcomes it.
Or simply burn out or at least overheat the servo.

I'll happily drive this... manual steering and doesn't seem to be a pain in the ass despite having no assist.
