I would suggest you turn Power Assisted Steering Off so there is no assist dulling out the feedback..

There is absolutely no way having the assist turned off is making it hard to perceive any difference in set up, no assist is always better as there is no reduction of feel from parts or adjustments by the assist. Asking us to use Power Assisted Steering On for testing is like saying we should test brakes with ABS turned on, NO because ABS gets in the way, same deal here, its as if your suggesting we need active steering to feel the difference, that is wrong, there is no way turning power assist on will make differences in rims apparent if there was any it would mask them, turning it off would make any difference if any more apparent and I believe using power assisted steering is what is causing your confusion.

Power Assisted Steering after much testing simply reduces the strength of the FFB effect depending on how fast you turn the wheel. Turning the wheel fast basically gets less resistance from the motors. It blows because a sharp fast correction or quick direction changes like through S-turns that I need precision on feedback gets dulled by a wheel going light, it SUCKS. I can see it being easier on the wheel tho, especially in cars like the X1 family.

I would suggest everybody turn Power Assisted Steering Off and only use it if your worried about your wheel breaking but know that using it dulls out the feel of the game and IMO totally blows. The more I test with it on its apparent that it dulls out the precision of inputs as the feedback is used to feel what is going on and the assist dulls the feedback. This is probably a good reason why many have issues feeling things or getting confused on what they feel,, the Power Assisted Steering if turned On is fucking things up BIG time but in a very subtle way..

Power Assisted Steering On is worse than ABS IMO Everybody should have Power Assisted Steering turned OFF..

Power steering is giving 1:1 turn radius as without it, only thing on racing it makes is harder to keep front tires traction because it's so easy to turn too much.
If power steering on gives every time same results from rims it's worth of it on testing. Actual racing is easier without it because wheel gives feedback better on edge of traction.

Can you explain what is this assistance what you get from power steering? It doesn't help a bit on racing, maybe only your hands are not so tired on longer races, but on cost of needed more precise steering to keep car on track. If speaking assistance it is more like anti-assistance when racing.

But I'll do that give car test first with power steering and then shuffling cars again and then without power steering.

Sure does, 1 to 1... I'm not suggesting it doesn't or there is any difference in turning radius.

Doesn't make any difference in traction, it makes a big difference in Feedback, the communication between the road and driver. It momentarily dulls feedback when making quick inputs. The Feedback is what is used to decipher and "Feel" things out, anything that works to dull the feedback is not useful in testing, actually it works to dull the feeling of differences instead of enhance them. It should always be off while testing.

I think Power Assisted Steering being on is massively causing confusion, your "feeling" differences that do not exist but you perceive them as differences the Feedback dulled is causing you trouble.

I truly believe this because the communication between the vehicle, road and driver is not dulled out by a wheel going light.

However you make the point that

"with it off the user gets better feedback on the edge of traction."

This statement is only Half True.

Its true that with it off the user gets better feedback that's my point and the reason why it should be off during testing, but the other part about the edge of traction is bogus. It has absolutely nothing to do with the edge of traction or feedback at the edge of traction, its solely about wheel weight to input speed all in the feedback. Holding steady at the limit of grip is exactly the same. Driving a car like my Spec Miata at the limit hides much of the effect of the power Assisted Steering because my inputs are so slow at the edge of grip, its when you make a fast input the feedback is dulled, even the Miata feels disconnected with it turned on although not as much as the GT-R LM NiSMO.

Power Assisted Steering Reduces the Force Feedback effect as you make fast inputs, it reduces the Feedback more the faster you turn the wheel.

Reducing the feedback dulls the communication with the driver, it dulls the Feel and therefore reduces the ability to Feel differences.. Makes it something that should NEVER be on during any type of physics testing as the as the physics are felt through the feedback, any dulling of the feedback is counter productive to testing.

Its not about helping Racing, that's not the point... That's irrelevant. What its doing is hurting our ability to feel out differences through feedback as the feedback is dulled.

Power Assisted Steering On nullifies results IMO.

Power steering helps during testing, it dulls conventional wheel resistance during turn, but leaves road feedback, tires are part of road feedback and rims including there.
It helps to produce identical turn radius during cornering.
These are reason why I say it is good for testing purposes. Without power steering game conventional steering FFB resistance is bit too high, unrealistic high on some parts, but suggesting also for racing use that, even wheel resists too much on some cases.

Now 550 km warm-up with real car is done, starting to buy cars and installing rims on them..

Pepsi testing.

Had to paint wheels matte light grey to hide Baja, used following rim set
ENKEI Baja x1
ENKEI RC-T4 x1
RAYS 57Xtreme x2
RAYS TE37V x1
All standard size, five identical HKS GENKI's two of them equipped with identical rims (57Xtreme's).
Driven online room at Tsukuba, all real and tyre wear normal, driving 5 lap race with all cars, no practise just race, last driving with this car was 24h earlier so only from memory how I recall them to work.
With power steering on.

All 5 of 5 felted right, I pinpointed all rims right.
RC-T4 and 57Xtreme made bit hard to understand which was which, so similar feel, after bit struggling figured which was which.

After sleeping will do same test again without power steering, first shuffling cars again.

I'm strongly standing behind my finding about how all rims are different and behaving differently.

No, it absolutely does not, it hurts with certainty.

No it does not "dull conventional wheel resistance during turns" leaving road feedback, not at all, it doesn't work like that at all, not even a little bit... It reduces resistance during fast inputs, you have the effect mixed up, its like we are not talking about the same thing. It DULLS the feedback from tires road everything when you make a fast input.

It does no such thing at all,not even slightly... It changes nothing about what direction the wheels are pointing in when giving any given amount of steering angle. All it does is reduce the resistance of the FFB motors on Fast inputs. I mean seriously its as simple as that....... The problem is we need consistency to feel differences and momentary dulling of the feedback reduces the consistency of the feedback, DONE finished, case closed...

I think you are very wrong and chasing BigFoot with this Rims business. I think your very wrong about your idea of Power Assisted Steering On being good for testing I think your confused on what its doing..... IMO its the complete opposite, Power Assisted Steering should be Off at all times during testing.

I don't buy your results, its going to be a tough sell. I don't believe in BigFoot...

I certainly believe that you believe there is a difference, I think your wrong, lets agree to disagree, I have entertained the idea for too long and there has been not one shred of evidence I've found to suggest your on to something. all I have found shows the exact opposite. I am glad that in all this I did test out Power Assisted Steering enough to make sure people turn that crap off especially for testing.

I'll do same testing tomorrow without power steering.
Shuffle-race-saverply-nextcar-race-saverply-nextcar..etc after all raced back to offline on gt-auto rim shop verifying what rims were, and having replays if making fail on car change and mixing "order", from replay could check time, and remarks on paper for felted order.

We don't have to argue this, I have informed now every one who is interested this, they could test and verify if they want, or test and made decision at there is no difference.. I'm starting to hunt some mail address to polyphony and ask verification directly from there.

I have been cracking GT for years and test physics often and Ive a good track record for my theories later on being proven in the code, much of the readers follow me because I take high pride in feeling out what's really going on when they get mixed or confusing answers elsewhere. I think many will think they feel a difference too, it won't surprise me.

Placebo Effect is all I see. Even after being told all they got was a placebo many refuse to believe it having been so convinced they were given the real deal. Some people give themselves a coffee enema because they swear they feel it helping them lmfao they know it works lol.. The Mind is a Powerful thing. I think therefore I am. You believe strongly there is a difference and so there is a difference to you if there is a difference or not.

I think the News is in Power Assisted Steering subtle but big effect and many like myself thought it was broken since 1.12

Before yesterday blindfolded test I was almost ready to start believe you as this is only Jedi mind trick, but five cars four different rims two equipped same and I could FEEL that placebo effect and name all rims correctly.. Never heard you could separate four different placebos blindfolded, and those placebos are identical every time.

Sorry but I'm convinced this rim thing, and I'm sure there will come others who can do blind tests and feel differences correctly. Not surprised if someone struggles heavily with rims like 57Xtreme and RC-T4, really hard to pinpoint difference, that's reason why those are on my test list. But if testing list is lightened bit, leaving there Baja and TE37V making 3 of other and 2 other, I'll bet at there start to come only correct lottery lines from that placebo.
Classic Steel would be nice to include on my tests, but it can show hubcaps on selection list, but with some friend later doing bigger variety of blindfolded test.
