I heard from some the lowered suspension makes clearance difficult on some roads. This would be my family’s one and only car. Is that an actual issue?
@likkuid For sure, depending on the roads and how careful you can or want to be when driving over them. Personally I feel the M3P is a bit challenged for ground clearance and suspension compression travel already, when stock, so to me it doesn't make sense to lower for street driving on nasty real world roads. But it depends on how well maintained the roads you drive on are. We drive on all sorts of ill-maintained roads, as well as gravel and dirt driveways on a regular basis.
Some people just hate seeing wheel gap and love the look of a lowered car. That's fine...you just need to know what works for you, and what your priorities are. Lowering should be good for handling on smoother pavement too of course, e.g. if you do track days or autocross, lowering should be beneficial for those (in theory).
Btw I did upgrade my suspension with aftermarket coilovers, and a few bushing upgrades too, because I wasn't happy with the handling of the stock 2021 M3P suspension. HOWEVER...I setup my coilovers to match my car's stock height.
That works much better for me and my wife (vs lowering). The car has since settled maybe 2-3mm lower, which is fine, can only really tell with a measuring tape anyways, though I may raise it up slightly at some point.
Apparently not all coilovers for this car support stock ride height, so if you ever go down this path but want to stay at stock height, like me, that's something to watch out for! Btw I'm not trying to steer you into modding the suspension, I'm only writing this because you mentioned lowering. If you're happy with the car's handling stock then keep it simple and save money by keeping it stock.
(However one word of warning: Please don't bother putting lowering springs on the stock dampers, unless all you care about is getting the look of a lowered car for cheap. The car is already underdampened when stock, putting stiffer lowering springs on it is not going to help the handling, especially over bad roads. I've seen lowered Model 3's bouncing around out of big dips and bumps, it looks terrible for ride and handling, and I'm sure what they did was put lowering springs on the stock dampers.)
Also, while I like the idea of selling the tires and switching to 18s, my concern with this is resale value as I would no longer have the stock parts.
I think that's a legit concern, especially If you might sell the car before it's really old and highly depreciated.
I kept my stock 20" wheels, no plans to sell them, even though I am also planning to keep my M3P for a decade or so and probably having the stock wheels won't matter much for resale once it's that old.
Same for our 2013 S P85 - still have the stock 21" wheels. Probably should have sold them years ago.
Was not aware ride and range would be the same…that is interesting. Thanks.
Yup. As someone mentioned earlier, when Tesla still sold a "stealth" performance that had the extra power and Track Mode but not the "Performance Upgrade Package" parts, it had identical range/efficiency rating as an LR on the same wheels+tires.
In theory the different brakes and the rear spoiler could effect efficiency too. But Tesla surely optimizes all of their brakes to avoid pad drag friction, and same for their optional spoilers to avoid any significant added drag. (Now if we were talking aftermarket brakes or spoiler I'd be very concerned about efficiency issues.)
