I was more concerned about the things you can’t change
There aren't any.
I had many conversations with people at Tesla
Which is a shame because most of them have no idea WTF they're talking about- as evidenced by you repeated a number of claims previously, factually, debunked with hard data.
I Truly believe (assume) the P3D+ only cost slightly more than the LR to produce, not counting the development costs. Either way it was developed for high stress driving and the LR or PD3- wasn’t according to Tesla employees.
Not sure what "high stress" driving is- but the + and - are
physically the same vehicle apart from the brakes, wheels, pedal/spoiler, and a 0.39 inch lower suspension on the -
You can verify this yourself with the online parts catalog Tesla publishes.
Same inverters. Same motors. Same batteries, etc.
You just need to remember you get what you pay for now starting somewhere in early to mid 2019.
Nothing, at all, changed in 2019 regarding P3D- and P3D+
Only thing that changed is some non-P cars (AWDs specifically) starting getting a 990 drive unit in the rear instead of the 980 that everything else always came with to that point.
FYI- the Short-range RWD cars still get the same 980 your performance has
We can all agree that the P3D- is slightly faster from 0-60 but may be about the same or slightly worse 0-60-0
That would only be true if you didn't put the same tires on both cars.
The brake difference would have
zero impact on that test. The brakes don't stop the car- the tires do.
(and indeed, owners here have tested this and found with the same PS4S tires the P3D+ comes with the 18" wheels and the 'regular' brakes stop the car in the same distance as those tires stop the P3D+ just as physics requires.
and absolutely worse if you had to repeatedly do it.
Eventually- sure. Better brakes don't stop you any shorter- they can't. But they can insure you stop the same as the first time over repeatedly stops without taking time to cool anything down.
But as noted, you can get better than the P3D+ brakes for less than the price difference- even paying to have em professionally installed- if you're someone who is expecting to do very frequent high speed braking.
as well as knowing the inverter and motors were track tested.
Again- literally the same parts on both cars as shown in Teslas own parts catalog and from pics posted by tons of actual owners confirming the PNs on their drive units.
