Anyone got some insight on these? Will raise the Model Y 1.2"; and seems to be a better option than those cheap aluminum spacers

H&R Adventure Spring Lift anyone?

What do you mean "make it worse"? It's common for people to want to raise or lower their vehicle.
Simply a taller spring. H&R lists the same P/N for both LR and Performance, so overall numbers would be about 0.5" less on the Performance.
MYP sits about ~0.5" lower than LR from factory.
Part numbers are different, but not certain if it's due the spring length or perch position as the spring/strut are only sold as an assembly from Tesla.
Not necessarily. Stacking a spacer style lift-kit on top will preload the factory springs also.

These Model Y lift spacers goes on top of the spring top hat thus not affecting suspension or pre load. Pre load spacers on the other hand installs to on spring in between spring and top hat thus causing pre load.
This still gets sandwiched between the lower control arm. You will be made aware of this when you go to bolt your suspension back up, a lot more spring compression in the rear is required before the control arm bolt holes align. The front is not as dramatic, and preload remains the same.

Red spacer is the "lift kit". It adds to the overall length of the whole assembly. Not much different than swapping out for a taller spring.
I may even argue a well spec'd lift spring will give you better ride quality.

You may be thinking of this from a lowering spring perspective. The suspension geometry cannot extend beyond the shock's fully uncompressed length, regardless of spring height.

Here’s the link to that lift spring test. From a knowledgeable Tesla shop in California
Of course, I'm aware. They also mentioned adding spacers to the shocks to allow more travel however ride quality was not improved. Which proves that's only part of the equation.
What I'm also saying is even a spacer style lift kit will still alter the overall ride comfort compared to factory.

Model Y Suspension:
Front 115mm shock stroke with about a .66 motion ratio for 170mm ish wheel travel.
Rear 160mm shock stroke with about a .87 motion ratio for 180mm ish wheel travel. .60 spring ratio.
Front spacer keeps stock bottom out to droop ratio. You need a 31% longer spacer for the rear shock to match the ratio and a shorter spring spacer.
The best way to do this is with a longer stroke damper that has almost the stock bottom out height, but more droop. Definitely DO NOT use a shorter aftermarket shock.
Longer softer springs would be best and just have a lot of preload. The current lift springs seem to have a higher rate.
Just spacers should not change the ride comfort in anyway.
