I have rear axle steering on my 991.2C2S - I have found it a fantastic addition. You do really notice it at slow speeds, tight corners, round abouts, twisties and car parks.

On track it almost a game changer - confidence through corners is significantly increased, which in turn allows for faster corner and corner exit speeds.

It became one of my must haves

For daily driving, there are almost no must-have options, RAS included.

That said, there are few options I would rather have than RAS.

Another point, very few cars have this feature - for me, I took the punt after driving a GT3RS and having followed it around a track. (I forgot to point out why I initially chose it as an option)

On my C2S, What surprised me most was how it enhanced the driving experience in daily driving and spirited driving in all manner of ways. It really does.

As an owner with this option, all I can say is, I'm very happy that I got it and I would do so again.

i wish my GT3's came without it.. did not like the feeling at all on highway and always felt a little odd to me at very high speeds..

i ordered 991.2 without it on purpose and without the power steering plus.

Can you clarify "felt a little odd", my finding on track was a combination of improved accuracy/consistency, much better feeling through corner (improved friction circle - higher limits), leading to higher corner speeds and overall much higher exits speeds.

In a straight line I didn't notice anything and that was at speeds of up to 225ish may be 230ish (long back straight down hill section).

I am genuinely interested in the subtleties of this option

100 percent order it IMHO. It's a huge development and does play a role every time you steer the wheel. PDCC is the one that I don't know is really worth it, as aside from maybe making the ride a hair hair better, it hasn't ever been something I really cared for. If you go GTS, go for that option.

ipse dixit

RAS, especially at high speeds, changes the driving lines -- at least the driving lines that one is used to in cars without RAS. This is what some people might find a "little odd." In my opinion, it's not a negative, just having to relearn how to drive the car, and once that relearning process is complete, it makes you faster around the same circuit vis-a-vis an identical car without RAS.

Around town, at more normal speeds, the RAS just makes the car more lithe, and feel smaller than it actually is.

OK, that makes a lot of sense - I suspect its subtle but certainly could account for the "odd feeling". I suspect it might allow slightly later braking too (which in turn may allow you to take a slightly different line).

Theres one corner in particular at my local circuit, which looks like a simple double apex, that can be taken two different ways (depending on how you want tackle the following compound corner).

I will try them both once I have the S broken in and report back. It will be also interesting to pull the telemetry from my GTS and compare it to the telemetry from my S (I've been meaning to do something similar to this for ELP_JC but my last outing was marred by a damp circuit).

Useful and interesting discussion.

Thanks a lot guys for all your opinions and thoughts. I went to the dealer today only to find out the April allocation is for 4GTS which isn't what I intend to get. I may still place an order and wait for an 2GTS allocation becomes available which is a hard decision for me because I really do enjoy my .2 base w/ 7speed manual which I ordered and built the way exactly how I want it to be. If I do decide to proceed to order the 2GTS, I will get the RAS and leave the BOSE off the list, personally, stereo system in a sports car does not make much difference for me. I have BOSE in my .2 base now and that's one option I don't mind giving up.

Why does the RWS requires additional hydraulic plumbing??

philippe911

no more plumbing with RWD,but for PDCC...............pump,puley,plumbing,etc............

RWD is only electrical, but the ad unbalanced weight................(half weight)

Resurrecting an old thread but just having got my car I can say that I'd rather have a C2S with rear wheel steer for performance than a GTS without rear steer. It's that good. You're much more likely to notice and make use of rear steer on roads and track than you would out of the extra boost you get from a GTS.

Do any of you have the RAS option with power steering plus? When would you need power steering plus? SA is pushing this on my build for a GTS I need to lock at the end of the month.

jlee504

Power steering plus really doesn't do much. I had it on one car and not on another. I can't say I remember the difference.

Rear wheel steering on the other hand is amazing.

Driven991

I had a 14 C2S with Power steering plus and now have a 17 C2S with sport package (includes RAS), PDCC, SPASM and NO Power steering plus. Power steering plus is a useless option to me, I would not get it.
