GT3 RS 4.0 Official announcement and video

[FTS]

Lightweight, welcome.

I'll add my personal opinions. I doubt that they did anything different to the coolant line connectors or the lines themselves, but I do not think anyone knows, save for Stuttgart engineers. In their view the issue is too infrequent statistically to "solve" it. And I do not think anyone has statistics to prove them wrong at this time.

As for the ice pedal: reading all the posts closely on this matter across the electronic world and talking with few race car engineers, I am convinced that there isn't a design issue with the ABS system. That is not to say that the ice mode does not exist, it does and we keep hearing reports relatively frequently. Just like any system, Porsche street ABS is designed to work within certain parameters, and we don't know what those parameters are. That is the reason, we are trying to collect data slightly differently per our thread in Problem Reports. I hope we'll have enough data some time in the future to either influence Porsche to look at the issue more closely or ourselves in using the system differently.

As others alluded, I am convinced the issue occurs with the way one uses the brake pedal in conjunction with tire, brake disk, pad choices. But I am speculating as well.

In short, do not expect those problems to be addressed with the RS 40, but I doubt anyone's decision here would be impacted negatively from it

Trackrat, TRACKCAR, FTS, thanks for the warm welcome and your super-fast responses (given the question, all the more valuable from guys who track their cars).

Regarding "ice pedal" my takeaway is that there is little reason to be concerned should one stick to OEM spec wheels, tires and brake pads.

It would be intriguing to find out from Porsche whether or not the coolant issues have been addressed. I'm going to put the question to the dealer and will post the response should there be one.

Thanks again!

p.s. Great encouragement to take the plunge on the 4.0 BTW! Once the dealer is 100% on the allocation, still to decide on White vs. PTS (if available), and steels vs. PCCB.
