M3P currently falls off above 40 MPH. So if you have a flat power curve and a goal of the identical 0-60, you don't need the same power at 40 MPH as before, because you're getting 40-60 faster. You can actually reduce your 0-40 if you increase your 40-60.
Aftermarket sells a tons of bushings for the Model 3 already. And M cars don't change every bushing or control arm in the car, especially in older M platforms.
Example: Look at this control arm for a 2020 M4, and look at the HUGE number of cars it fits on from 2012 forward, including many base models:

The Model 3 already has a complex multi-link suspension front and rear. Even the 911 had McPhersons until recently. Shock and spring tuning is everything. Anyone that races a Model 3 will tell you to change the shocks and springs long before you throw bushings at it. And before that, they'll tell you to get some camber if you actually care about lateral grip (before you slap huge range reducing tires on it).
But it's also clear that people don't want a race car in a M3P. Search "Tesla model 3 stiff suspension" and see how much Tesla got beat up for the Model 3 suspension when it first shipped.
It's such a shame that when the parts catalog was up that nobody looked at the interesting things such as control arms to see if there was a "sports" version.
