According to the lifter manufacturer
https://www.mountainpassperformance.com/product/mpp-1-75-suspension-lift-kit/
"The range will be mildly reduced..."
I might inquire to see if they have any comparisions.
Can a dam help ?

Contrary to what many people believe, with a smooth bottom, drag goes DOWN with
increased clearance. That's why solar racers tend to have 10-12" clearance
under the body.
With a typical ICE the underside is a mess, so they can benefit from a dam to
keep the air flow out from there, but the bottom of Tesla Y is pretty smooth.
I think you'd be better off without the dam. It might even get better milage
than at it's normal height.

I'm reconsidering buying a tesla Y. It's a crazy amount of money and I may get
cold feet. But I
have to replace my ancient honda or keep fixing it (which is costing average
$2k / year). And, I
want to replace it with something that is adequate for going on the cascade
mountain forest service
roads, as well as modest road trips.
I could buy the Bolt, which seems to be an excellent car. But I don't think I
can using it in the
mountains. That's a must, since I'm there perhaps 20 times a year.
My biggest concern with the tesla is damaging the battery or other critical
underside stuff. On my
honda, I've had numerous ground strikes but no serious damage. It has 6.5"
clearance. I found a
company that makes 1.5" suspension spacers that fit in the model 3 and the Y,
which would give my
8". I think that's enough that I can visually judge and slow down, so as not
to have a severe
strike. (It's harder than you think, if the sun is casting tree shadows across
the road - almost
impossible to see any deviations.)
If I raise the chassis, I'll get more drag. Thus, the question of installing
some kind of skirt.
Does anyone have advice on this ? Would it make a difference ?
(P.S. I'll keep the honda odyssey regardless but drive it only for hauling
large stuff. Maintenance
should be minimal.)
