Spyder75

I've done 3.5kms in mine and the sport exhaust has been on for about ten mins max in total...!

Doubling the spring rate, faster and much broader adjustment PASM, double the camber (with more range for adjustment of all alignment settings), replacement of bushings with monoballs, stiffer anti-roll bars, wider track, large reduction in unsprung mass (forged centerlock wheels, centerlock hubs, lighter rotors). Just off the top of my head. All that is considered “very minor suspension tweaks”?

you also spoke nothing of the differences between the GT4 and GT4 RS in:

1. weight reduction
2. transmission
3. aero
4. cooling

Pffffffft! Not fair to bring facts to an Internet debate!

Funny, some people act brash and snarky online but are timid in real life. There’a no reason to be snarky. How would you describe the GT4RS suspension?

To my knowledge it’s the same strut suspension front and back as the GT4 with lowered springs, different damper settings and, stiffer anti roll bars. I would consider those minor tweaks to the basic GT4 suspension design but if I missed something please enlighten us.

The fact is if the GT4 was so good, then why change anything with the RS. The fact that Porsche tweaked ALL THE ITEMS ON THE GT4RS that MANY dont like and end up modifying on their GT4's is a VINDICATION of just what we are saying about the things we do not like. Archie, you used to be so much better at this - what happened to you?

I’m speaking about the suspension and yes I would consider those suspension tweaks as the core suspension is the same. Midengine, Struts front and rear, pasm dampers.

Unsprung mass isn’t technically part of the suspension but PCCBs and magnesium wheels would have the biggest impact and last I looked they aren’t standard on the GT4RS either.

And just to be clear, I love the GT4/Spyder. Afaic, the GT4RS is the ultimate 718 and likely the “funnest” Porsche you can buy. It goes without saying the RS suspension is optimized for the racetrack. My point is that I don’t understand why someone who finds the handling characteristics of the GT4 “uncontrollable and unsafe” would buy a GT4RS. That’s it. If I strongly disliked like the handling of the GT4, I’d look for a GT3, GT3RS or something else. That’s it

You missed a lot. Re-read my post above. The GT4RS is no lower than the GT4, but the springs are 2.2X the stiffness (100N/mm vs 45N/mm for the GT4).

By that logic the differences in suspension between a base 991.2 Carrera and a 991.2 GT3RS are very minor as well. It seems to me that your bar for what constitutes a significant suspension change is a complete change in geometry (like the double wishbones on the 992 GT3 vs base 992). Since the suspension from the 993 Carrera all the way up to the 991.2 GT2RS carries the same geometry, would you also make that same assessment?

Also, the centerlock HUB is most definitely part of the suspension, is lighter than a 5 lug hub, and is standard equipment.

I would gladly take that 5 lbs. penalty and get regular lugs on a GT4RS....

greatfox315

I’m the opposite. Every pound counts. Plus I already have a 900 lbs/ft torque wrench ready to be exercised

jmartpr

You will loose those pounds changing wheels at the track!
On a serious note...need to buy all the tools for CLs

Wow - how about a photo of that monster? Does it have .75" square or 1" square at that size? You want .75" for the socket that comes with the car...

You took my words out of the context;

Only at very high speed driving, the fact is I don't do that very often, and the one time I did it I noticed the suspension flaw.

On B road driving it will be excellent.

That's why I want it, the last ICE and one of a kind GT4RS.


My preview 718GT4 was a brilliant platform, only not at high speed bumpy German BAB driving, thats all.

Checked this thread to see driver feedback, still filled with many people who haven't driven the car opining on how it drives....
