I still have my RSS ones and compared them to my GT4 take offs. The increased track width is 4mm per side. The rear camber on the RS is reported 1.75 compared to the regular 1.5. On the regular I increased to 2.2 (~7mm). Running out the adjustment screws there appears to be enough length to maintain safety thread engagement.

I would think adjusting the STOCK suspension is fair game for the ring assault.

I agree... also bear in mind that any Ring time Porsche counts is probably done on Mich Cup2 Rs. Other than that, it should be stock

The Nürburgring has a new protocol for lap timing where they are including much more information than ever before in the official press release. I think it includes the exact lap time for both 20.6km and 20.8km laps and also specifies the exact tires used and the precise alignment settings including camber, ride height, swaybars, traction control setting, aero settings, etc (maybe even tire pressures too). Basically, it's designed to provide all the info to allow a customer to duplicate all the settings.

I remember seeing this very detailed info on the Nürburgring press release for the AMG GT Black Series when it set the production car record. This is a very expensive process (have to rent the whole track and pay the Ring for all of its timing, scrutineering, and communications services when setting an official lap record).

Maybe Porsche didn’t bother with all of this, because there was no real record set (except among Boxster/Cayman models).

Still doesnt help me... I wanted to know how this compares to the 992 GT3s stiffness on the road.

^^^You are overthinking this.
Stiffness on the road - they are going to be close enough that which one you choose doesnt matter.

GrantG

Exactly - they are both most at home on a track or smooth roads and neither will be comfortable on broken pavement for long trips. If one rides 5% better than the other, it's irrelevant.

If one was going to use either exclusively on the road and wanted more comfort, then you could consider an aftermarket suspension (GT3 might be easier to swap as you just need to exchange dampers and coil springs and not the whole wheel carrier assembly that is integrated with a strut suspension).

Adrift

They will never be able to make nearly enough of these cars, even with the overly rough road manners; which is why I am hoping the (mythical?) spyder version becomes the 718 speedster. Oh, such perfection!

welikethetrack

That is absolutely false. The difference between the 991 Gt3 and the gt3rs is literally all suspension and aero to get the much much faster Nurburgring time.

The ride quality is very very different as someone that has driven RS and normal gt3's.

The RS feels much much stiffer on the street than the normal gt3, so if you're worried about that absolutely get the gt3 and opt for the standard seats or 18 ways.

Also I daily'd an 991.23RS for almost 3 years, I don't think I will ever do that again. I will absolutely DD normal gt3/gt4 with the sofas

GrantG

I think you are confused about the comparison being requested. It is between the GT4 RS and the 992 GT3 (which has about the same aerodynamic downforce and suspension compliance as a 991.2 GT3 RS). The 992 GT3 and 718 GT4 RS will have similar road comfort (or lack thereof).

blackmist27

I expect it to be stiff... I think that the 992 GT3 was pretty stiff when I had it. you could just about deal with it because not a car you drive to Costco. BUT if the GT4RS is a stiffer proposition, I just fear I wont use it enough because I dont track every month. if its slightly more managable than the GT3, then I will be happier. but I guess well see.

GrantG

I think it'll be very hard to make a judgment about small differences from reviews, until you are able to try for yourself. On the 992 GT3, the reviews are all over the map and the subjective impressions seem to be very much influenced by things like the quality of the roads, ambient temperature, which of the 3 OEM tires are fitted, and even the tire pressures used.

My guess is that the 2 cars will be very close...

I like his reviews, as he typically doesn't sugar coat anything. He said (for most people) it's not a car you would daily, but I would assume that would be the case for 99% of the people fortunate enough to purchase one. The two things that make the car great are simultaneously the same two things that hurt it's daily drivability - the suspension and the noise. Anyone who buys this car and complains about either didn't do their research, so they should sell it to me and go buy a 991.2 GT3. IMO, the GT4 RS being too stiff or loud to daily (for some) is totally excusable, as it's an RS car. Although I haven't driven it myself, the 992 GT3 may have been where they pushed it a bit too far, considering the 911 GT car demographic. It makes you wonder what the GT3 RS will drive like... Where can they go on the 992.2 or even the next gen 911? How much more time can you squeeze out of the current formula, other then tire tech?

blackmist27

You are probably right... the 4RS and the GT3 will be close. if thats the case, then I guess its ok. if the 4RS is significantly harsher than the 992 GT3... then FML
