Yeah- at the time this was originally announced (back in 2018) reaction was mostly "why bother?"
It was pretty obvious the "performance upgrade" package...wasn't really an upgrade in most regards.... the wheels were heavier, more prone to damage, but not any wider... the suspension change was hardly noticeable and didn't offer "real" upgrades like magnetic dampers, and the brakes were both underwhelming for the "upgrade" version and made aftermarket wheel choices much harder.... the tires were excellent but that was about it.
Finally almost 2 years later they're asking another $5500 for a "real" upgrade for the wheels/brake pads at least... but all the folks who smartly got a P3D- instead and care about tracking went aftermarket already anyway on that stuff and generally got more for less $.[/
I guess you could upgrade brakes, lower suspension and upgrade wheels via aftermarket products but I’d rather have it all come on the car and manufactured by Tesla themselves. Performance models will also hold a higher value in trade market, not a stealth with several aftermarket upgrades installed via 2nd or 3rd party.
