who starts the list? for the engine. and also the chassis.

don´t forget the 100% and 50% harder spring rates,
rose ball joints (except the ones connected with the rear wheel steering)
updated PDK (is it possible to re-map? or is there also a hardware difference?)
front brake cooling
rear diffusor
car media
reverse camera
100g lighter rims each corner
and!

the special tires!

So they changed this without public notice? Any differences in power or something? On the website they still claim "Powering the new 911 GT3 R is a cutting-edge four-litre flat-six unit which is largely identical to the high-performance production engine of the road-legal 911 GT3 RS."

rear section was on .1RS already titanium.

just noticed torque is measured in nm .. the GT3 & RS dyno charts have a slightly different intersection at rpm, where hp & nm meet. One of those dyno charts is off.

Does it matter if they sound different even if they are "largely identical?"

In other words, no internal differences...

Maybe two completely different types of measurement; one is steady (Porsche) and the other transient (aftermarket)?

Hypo question. A .1RS hits the COTA back straight at the same time as the .2 GT3. Does the RS pull away?

The GT3 should pull ahead on the straight, due to less drag (much smaller wing, hips, wheels/tires

.2 GT3 pulls away over 80MPH.
The best .1RS can hope for is existing the corner enough MPH to keep up..

The biggest real world difference you can feel between the two cars in the past, wasthe amazing front end of the RS... The extra wiDTH and rubber really gives you an incredible turn in ability. I don't think the other differences like downforce and any extra engine power are apparent in most situations. Many have more experience than me I'm sure, this was just my impression.
