Do we know yet if the changes to the 4RS' suspension do anything to decrease bump steer and specifically to mitigate rear toe deviation on compression/rebound?
I'm aware of new toe links and stiffer springs/dampers. The stiffer springs/dampers should help as long as there's a good amount of added compression in the front, rebound in the back, increased spring rate overall, caster adjustability to keep the track at original levels during alignment, and minimized deflection at the toe links. With that said, it seems like the toe deviation problem on the 982 all originates from the linearity (or lack thereof) of its toe response curve to suspension travel.

Porsche marketing materials said they increased front and rear negative camber on the GT4 RS relative to the GT4, and showed different (longer) toe links on the RS relative to the standard GT4. Not sure if that change made any improvement to bump steer characteristics too.

Artic Silver or Blue as far as I can tell, and this: https://www.suncoastparts.com/product/SKUALCGT.html

P1 Designs can make you whatever you want for a fraction of that, and Kim is great to work with.

Intermediate
And are the increased track widths likely just from them adding camber via the lower control arm?

Ohhh in that case they got to fix the description in the configurator.....so for buckets if you want factory you need to go CXX? I rather go P1 Design or other supplier unless you really need it to be spec from the factory.
Porsche has this little things that sometimes I don't get it, welll I do get it...more $$$$$$...it was like my Python green GT4 with deviated lizard green stitching/belts...everything got changed to lizard except the door pulls and in 2021 lizard door pulls were not an option, so needed to go via CXX.

The new front fenders look like they could be slightly wider, so they could have achieved wider track with a different wheel offset. They can also change alignment with a different top hat (like the 991.2 GT3RS)

981/718 GT4 and 718 GT4RS all share the same offsets and wheel specs......difference must be in some area of the suspension components.
Could be the wheel uprights as these are CL contrary to 5 bolts on the previous models. The difference is not that great so it could also just be shims on the LCA......

With my GT4, I think the cost was $8800 to do CXX customization (Porsche logo in headrest with orange inserts). They told me any mod on the seat is the same price regardless of how little or extensive it is.
