Yeah, the cost of keeping two cars in running order can be significant in Australia; storage, rego, insurance, servicing, fuel, consumables. That can easily add up to a few grand every year. You have to really want more than one car to justify up to double the running costs. I cannot. So I need a sportscar with at least some practicality.

Wow that is expensive. The 16BRZ is my DD unless it snows then the WRX in winter. Extra cost a year is about $800 insurance, registration $75, $37 inspection, $80 for 2 oil changes. Do all maintenance myself. So cost is less then 100 a month. Remember maintenance is generally based on mileage. So you can only be in one car at a time, so the miles stay the same but are split between the cars. I could go a whole year without changing the oil on the WRX, but for 40 bucks I just do it about every 6 months. Also I have no fear jumping into a project on the car because if I can’t get it done or I am waiting for a part, I have a second car to get to work.

I have to admit with my hobbies I do go overboard. I love mountain biking and have many bikes. It’s a disease. Saving up for a weekend toy for my 50th bday next year, maybe a used cayman or C7.

If you can afford having two cars it is way better than one, even better than one more expensive car.

Also, wouldn't a lighter aluminum knuckle make the rotational inertia of the system lower, thus improving responsiveness?

Consider that the knuckle is the connection point of the strut, the steering linkage and the control arm. It's probably the best point to stiffen up without negatively affecting ride like stiffer bushings would.

The knuckle doesn't rotate, so no rotational inertia in play here, but unsprung mass? yes. However, the current twins have cast iron knuckles and have a delightful tactile feeling, so I see it as sticking with the current weight and stiffness instead of going to a lighter, less stiff setup.

Is there any word on if Power Steering tuning is the same between them?

I've owned two cars most of my life.
There was always a better chance one of them would start.

The JDM model reviews have all noted a change.

The BRZ is heavier than the old car, the 86 is lighter but I haven't heard if it was lighter than the old ones, or just lighter than the BRZ.

That’s good to hear. I wanted less assist in my BRZ. I wish they would make the assist level a user selectable input.

Yeah I agree! Sounds simple, yet I cant recall anyone doing that.

Ford does this. I recall their earliest was the 2nd gen Euro Focus. The current and previous Mustangs have steering modes, however I didn't like them. From what I remember (it's been 5 years since I drove one), normal mode is very lacking in feel and makes the car numb. The sport mode I remember being artificially heavy but not really helping actual feel, but much better than normal.

Maybe I'm getting older but I much prefer no modes, just a single well tuned steering system rather than a few mediocre to bad ones. Took me a day to get used to the FRS's light steering but I can say they did a fantastic job, the only light steering EPS that offers a lot of steering feel, I was personally worried about EPS because so many sucked before then. To hear possibly the newer cars adding a bit of heft, I'm very eager to try, perhaps even better balanced than before.

BMW does it too, but it doesn’t work either. I think the problem is that those EPS systems don’t have enough feedback so reducing assist will only result in heavier steering. I think you need a rack with good feedback for any of it to feel right, regardless of assist level. Sadly most steering systems are tuned to isolate the driver because the vast majority of customers don’t like steering feedback. The Twins being a niche car helps not having to cater to them as much.

Also this. https://www.roadandtrack.com/car-cul...ich-is-better/ In short, EPS generally have less feel due to the higher inertia of the motors connected to the system damping out the small vibrations.

But I guess mpg sells so EPS it is.

Anyone knows if the current gen twins have a positive or negative scrub radius and how much? I read an old post saying its +20mm? But feels a little too much? Didn't seem to come across any other info.

Would be nice. It can be done.

The user can fine tune the 5 adjustable steering maps (via a rotary position switch)

Sounds like it would be as simple as filtering the signal from the torque sensor.

It would be neat to see the aftermarket pick this up if the demand is there. @ is this something that’s attainable through a remap?

Arent drive modes are supposed to do that.
Obviously to various degrees of change based on manufacturers settings. (some barely make a change, others have more noticeable changes)
And because its a manufacturer setting, they might not be ideal for anyones personal preference.

Just so happens the twins dont have multiple drive modes.
