Can anyone corroborate this? Whether it affects higher speed driving in any negative way?

I have it on mine, but am curious what it's actually doing. My car feels amazing++ to drive, but I haven't driven enough modern Porsches to know how it's affecting steering feel.

My SA told me it was a 'must have' feature for a daily driver vehicle (most of the fourteen 991 models I test-drove seemed to have it).

An educated guess would say that, as this is purely a software change for the electric steering system to adjust steering ratio at lower speeds, that there should be zero effect at higher speeds.

Other threads suggest you can have it deactivated (or activated later) via software update at dealership.

Suncoast sells it as a separate item on their website - it's definitely something you can activate (and I assume deactivate) at the dealership.

It's not politically correct, so Porsche will not say that it is intended for people with small or weak arms. Or maybe one weak arm. Small women, very small men, or handicapped people might appreciate it. This is not a needed option for normal healthy adults. I'm pushing 75 and am 6'1" 167 lbs and skinny arms, and I would definitely not ever want or order this option. It is not what any physically normal adult would want.

It's a must.

It makes it so much easier to navigate rush hour traffic while holding a cappuccino, and texting my order to Grubub for that night's dinner.

Your SA likely just wants to sell cars. Since most cars by dealers are specced that way, they try to move them off the lot so need to say that. It’s definitely not required for a daily driver, and I would venture that most people on this forum that build their own do not include it. Someone should do a poll. More importantly, people should just test drive with and without. PSP feels mushy to me. Normal feels right and precise like a sports car should feel like.

Two718s

So I have two new 718s, a Boxster with PSP and a Cayman S without PSP. I have a tight, curving driveway to back out of, and I frequently park both cars in a large multi-story garage where the spaces are quite tight.

After two weeks driving the Cayman S, I finally gave up and ordered the PSP software from Suncoast. I will often drive both cars back to back, and I can't tell the difference at normal road speeds. However, when maneuvering to park, the Boxster is *vastly* easier to maneuver. There's just no comparison. PSP also makes the car feel smaller and more nimble when maneuvering in and out of parking spaces. I tried to parallel-park the Cayman the other day -- I grew up in New York, driving cars with no power steering at all -- and my hilarious attempt to parallel-park the Cayman made me realize how much I've come to rely on PSP in the Boxster. (Of course, the fact that the Cayman has 20" wheels and is therefore much more susceptible to curb rash, may have made me even more hesitant than normal.)

If I lived out in the country and spent most of my time on open roads, I wouldn't bother with PSP. But for anyone who regularly parks in tight spaces, I find PSP to be supremely helpful.

Going in next week to get it added to the Cayman S...

This is nonsense. I’ve owned multiple Porsches with and without PSP at the same time. It only affects steering at low speeds and even then the difference isn’t huge. Stupidest debate out of all the option debates.

I even had two 981s, one with and one without. Zero difference at speed at minor difference at low speeds.

I'm confused. Are you for or against PSP?

So hypothetically speaking, would adding Rear Axle Steering be considered as an alternate to PSP or does one complement the other, so both are recommended?

If you have a RWD model with RAS the steering is perfect. I would consider it on an AWD model without RAS as the steering is noticeably haleavier at low speed.

I received my 992 (2S) a few weeks back, I opted for RAS but did not go with PSP. This was a conscious decision (that my sales guy advised against) as I didn't like the overly assisted feel of PSP in my previous Cayenne (2019). My 992 is a bit heavy when parking for example, but this set up feels more natural and suitable to the type of car it is in my view. RAS keeps it feeling nimble as well and I imagine it would feel a bit heavier still without RAS. As someone already wrote PSP is a software rather than mechanical option, meaning it can both be added or turned off, and its a fairly cheap option

darkblack

Thank you, that does clarify it much. RAS without PSP it is then 👍🏼

pelucidor

Exactly this. I drove several 991.2s back to back (trying to decide between cab and coupe, and between C2S and C4S etc) and the cars that had PSP were a tad less steering effort when parking compared to ones without. Honestly with/without PSP is not a big deal - and even without PSP there is still much lighter steering effort than some cars I have had (e.g. BMW X5M - heavy car with 315/35R20 tires on back). I think feel/accuracy is more important than heavy/light effort and I am hoping the 992 is better than the 991 in that respect.

dhirm5

Thank you. This is what I wanted to know. Less effort at parking speeds is a plus IMO, as long as normal driving is unaffected.

PSP and RAS are not substitutes for each other as they do two entirely different things.

As to what I prefer, PSP or no, I was indifferent, maybe 51/49 pro PSP. I liked it but not enough to spend the time and money to add it to my cars that didn’t have it. The only real opinion I had/have is that those people who claim that PSP is this massive change that turns a 911 into a Lexus are wildly exaggerating. If I were buying a new Porsche, I’d probably add PSP. You can always turn it off if you don’t like it.
