I'm not an expert. But from what I understand, there's a difference between a helper spring and a tender spring. The springs on these cars are helper springs. They should be fully compressed under vehicle weight. If, for some reason, the suspension is 100% unloaded and goes into full droop, the helper springs expand and keep the main spring from coming off the perch. That is the helper spring's only job as far as I understand. If they were tender springs, it'd be a different story.

i personally will be many years from today faster with the RS as with the ACR. but its an event. driving as owning it. i guess it feels similar like going to a US Bimmer Trackday in an E46CSL.
here are A LOT of fans for the ACR.

regarding warranty. there is no possibility from Dodge within EU. just other / second hand ones. cars as warranty options. i can only wait till the rear window blows out, or to see if i had badluck with my engine, etc... will be more expansive here. but maintenance is not an issue within the region. a lot of good (also US Cars) specialists in an area of 100miles.

but why you think having to sell if somebody want to set it up professional? i know a couple of guys which are quite happy with their Acr. and they track it also often.

fur sure it is the closest benchmark for the .2RS ring time.
and than comes the performante. but this i don‘t believe.
sub7. also if i remember well: around 7 was stopped from Mischa or Dale during the first GT2RS record laps.?

My hope is sub 7 minutes. 7:10 would be only 2 seconds faster than the current GT3, over 11 miles. That would bring new meaning to Porsche’s incremental improvement policy

Agreed, that's my understanding of the spring setup on the RS, even the new one. ie it's a helper spring not a tender one.

Exactly, there is nothing tender about the new RS. It's badass.

Maybe I wasn't clear. Yes they are helper springs, their objectibe is to give traction, they do this by creating extra travel to suspension when the road is either uneven, when therr is bodyroll or in this case when the chassis is very rigid and suspension travel is small and you get a 3 wheeler. With helper springs you get the tires in contact with the road faster than without and you will always have more traction when cornering as no matter how much more rigid the 991 is, there will still be body roll. The comfort I speaked of is stability of suspension as you will have the 4 wheels on the ground at pretty muh every situation. The wonders of soft springs is traction that's what helpers help with.
Soŕry if I was unclear.

The selling bit was a joke and I was talking about the rs not the acr. The acr properly setup and running a good suspension (shout out tractive/dsc sport) will just murder an rs no matter the mods.

one can only dream
But yeah it will be faster more than 2 seconds. 7 to 7:06. With manthey treatment it might achieve sub 7

I suspect that the 991.2 GT3RS already has a lot of the MR treatment from start.

you would know better th
an me, but the wheels at least were tested on their cars and customers cars. I think they offer a solid ball mount too, so I would guess that was too. I was talking more about alignment and maybe kw suspension.

p.s. why isn't there an gt3 or rs trying out tractive on nurburgring?

With all this talk about the RS performance on the track, we should be concerned about the driving dynamics on the street. With major changes in the chassis and suspension, what's it going to be like driving regularly on the street especially compared to the .2GT3?

100% stiffer springs will make it less compliant over rough roads for sure...

compliant or comfortable? If I were a betting man I would bet you that the damping is much better and it will be more compliant even if it has an harder ride

A car has 4 times the downforce when traveling twice the speed.

I wonder when Porsche is going to provide an active rear wing like Lambo and McLaren to reduce drag when going straight? This will make a big difference to Ring time.
^^That , and active aero braking/downforce.
