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.

Hit a nickel laying on the road and break both your arms

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.

Apart from all this talk of wires...

I find the feel and weight of the steering (made better with quality 225 wide rubber) one of the best things about my car.
Braking, sliding, ‘powersliding’ etc are all easy to feel and modulate and I always know where the wheels are pointing and what they’re doing.

Heavy duty rack bushings and STI rack bolts make it even better. I think they did a great job. Love the steering.

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

yea, I was one of the crazy ones. 14x5.5.
