This is a very interesting topic for me because I've never been to a driving school/lecture before, I'm learning so much from you.
I've got a question on the point of steering load increase as lateral load increase, does that apply to all kind of steering rack? be it assisted by hydraulic or EPS or even unassisted? because when car journalist review cars they always says car with hydraulic/unassisted steering has a better steering information than that of EPS. they always point out car with EPS usually felt numb and doesn't give feedback to the driver.
Yep, steering load will always increase, regardless of assistance or lack of it.
What unassisted steering will give you (potentially) is direct communication from the tyres, which is always going to be diluted with assisted steering to a degree. Now in terms of which is better in terms of retaining steering feel, that's an easy answer, as it's hydraulic PAS. which is not to say that you can't get good electric-assisted PAS, Porsche EPAS has a solid reputation and my own I30n is pretty good as well. And all of them are going to let you feel the build-up and loss of steering force. Interestingly with EPAS, you could in theory, reduce the steering weight to zero, but no one would want to drive your car, as it would feel utterly alien, as anyone who ever had FFB drop-out in a title will attest to.
The issue with EPAS systems is often additional weight is added in, as many people think it's more 'sporty' but it can often then mute the road feel you ideally want as well. However, that's not the only thing in the steering and suspension make-up that can mask that granular feel keen drivers desire, as your steering and suspension set-up is full of rubber/poly bushes, all of which are present to reduce 'Noise, Vibration, and Harshness'. NVH as it's abbreviated in the industry is something that great lengths are gone to (as in millions of $), to reduce to an absolute minimum, to make road cars as comfortable as possible, drive a purpose build race-car and you will soon find out why, they are noisy (and not just from un-soundproofed engine noise), and the rose-jointed suspension and steering, which removes all bushes combined with race stiff springs and dampers are harsh to a degree that shock people for the first time.
In terms of steering rack systems, basically, everything on the road these days is rack and pinion, with good reason. I semi-regularly drive a number of old Series Land Rovers, which all have either 'worm and nut' or 'circulating ball' systems, which offer almost zero feel of any form whatsoever, and are unassisted and are better than a work out at the gym when it comes to low-speed steering.
Yeah, I don’t think torque should be set too low. The game doesn’t translate bumps well with a low setting. I think the sensitivity needs to be turned up also for more pronunciation of road surface. If torque is 10 and sensitivity is 1, the wheel would just feel dead heavy and won’t react to surface bumps. With a low torque and high sensitivity, steering is light but the torque transmission isn’t enough to dictate steering movement. I set torque and sensitivity at both 8 and can’t really differentiate my actual car steering weight for the game in all driving conditions.
Oh, I 100% agree, as a mainly PC sim racer FFB setting is a little bit of an obsession.
With my T300 in GT7 I run 4/2, any more torque than that and the steering weight is unrealistically heavy and starts to clip (which you 100% want to avoid), however PD, even for a console title, fall well short of enough options to get a wheel dialed in fully.
Like slow corners almost without any throttle are 50:50. Faster ones are different, but the same.
