@KimDicus2003 For street driving, stock height is best for comfort AND performance. Unless your streets are all racetrack smooth. I haven't been to Hong Kong, how well maintained are the roads there? Are there many big dips, potholes, speedbumps, steep driveways, pockmarked pavement, etc?
Low is slow on the streets anywhere I've lived.
If you're focusing more on track days, or just love the look of a lowered car, go for it! But don't kid yourself that it's making you faster on real world roads with potholes, speed bumps, speed driveways, pockmarked pavement, etc. You'll just hit your bumpstops and scrape more, and likely drive slower to minimize that.
Edit: To be clear, stock Model 3 suspension is mediocre. A mildly lowered Model 3 on good coilovers should easily handle better than stock even over the worst pavement, and can ride better too if the springs and dampers aren't excessively stiff for street use. From what I've read here, it sounds like KW V3 and Ohlins R&T coilovers (those brands' "off the shelf" options) are both quite stiff, intended for a mix of racetrack and street use. I would highly suggest MPP KW, Redwood Ohlins DFV, etc for offering much more finely tuned options for different use cases.
