My 1LE has ~ 1.25 in front, but more like 1.75 - 2" in the rear. It would look better if rear was more level with the front.

Man. Huge difference.
The front on my ZL1 looks like a full inch taller than my rears (it's not, but it seems that way). Waiting on reports back from people who have had theirs changed out at the dealer.

I will be keeping my fingers crossed that someone actually gets this accomplished.

For almost an inch of extra height, it could be written up as a performance/driveability issue.

Exactly

At dealer and they can’t find any TSB relating. Guys, any numbers or way I can point the service advisor in the right direction?

I gave him that number. He said it wasn’t a number they could look up. I’m baffled.

Went in to the dealership to ask about the TSB. They're overnighting the springs and taking care of it on Monday!

I actually don't mind the extra travel, but could anyone confirm if there is an actual performance benefit having the lower springs??

I'm assuming the ring' time was done with the originals...I see no benefit to doing it myself if it is simply a stance preference.

ninetres, what exactly does that measure as it's sort of at an angle...mine is right at 2" and was a Feb build I reckon since I picked her up on March 10.

The forum rotated the pic for some reason. That's not how it's orientated in my library. And it's hard to hold the tape in the absolute perfect spot, at the perfect angle, and take a pic which is VERY sensitive to exactly where the lens is in relation to the tape for accurate viewing. I tried to have the tape aligned with the center of the hub. Was just offering an additional data point for this discussion. My bad.

And FWIW it's shows ~2 3/8" to the circumference line to the fender. Very unscientific but you should get the point.

For me the issue is the stance however one could make the point if you have the higher stance too much air going underneath the car maybe causing lift at speed or maybe the mag shocks take care of that, who knows, LOL
