Default Rear ride height measurement requested

Could someone please get me a measurement from the rear T/A Bump Stop to where it hits the trailing arm?
On a fully assembled car?
I am building my suspension in bare frame mode.
(Please include your rear fender height and tire size.)
Mine seems very close:

Is 1.75" here really correct?

Happy to help, and my car is hanging in the air at the moment. But totally unclear as to the measurement your looking for.
snubber to what part of the trailing arms? And it would have to be much, much greater than what your asking about.
How do you wish it measured?

OK , so I'm looking and looking at your photo.
you want a measurement from the bump stop to the trailing arm! Not the snubber which is the forward diff mount. Thus my confusion.
with my car hanging on jackstands waiting for parts from the states this I can not get at the moment.
FROM THE BUMP STOP. TO THE TRAILING ARM!

Yes there is a flat plate on the trailing arm, that the bump stop hits. That is the measurement I am looking for. A tape measure is fine. Within an 1/8" or so maybe?

I set my strut rods according to the factory AIM "D" measurement of 2.1" and I only get 1.75" here. But I do have 2 mods that are probably messing me up. The lowered diff crossmember with the VS bushings, and the VS smart strut bracket. Both of these mess up the "D" height and I am having a hard time compensating, and coming up with a measurement that makes sense. 1.75" clearance on bumps just does not make sense to me!

Plus my QA-1 shocks are going to bottom out (with no more travel) 1/8" before the T/A arm hits the bump stop! WT*!

I'll change strut bracket back out today and do some more measuring.....



The AIM says the rear "D" height should be 2.1" with no-passengers. How can this be if there is only 1.75" of suspension travel? Confused.... And over on the right it says there is 3.5" of Ride Travel on Jounce?????????

If it helps any...

The little v-block is 1-3/8" in this axis


Just slides in under the rubber pad with a very slight interference, the pad is pretty soft still


Fender height 27-3/4"ish


Conti 235/55 17" which they say is 27.2" tall

Perfect. That helps a LOT Mooser!
Thanks!

Yours is almost dead-on the factory measurements too.
It is just a lot less clearance than I was expecting.....

Those bump stops must hit occasionaly......

Mine shows sometimes the pad touches but changing to the bilstein shocks helped a fair amount.

My 1/2 shafts are pretty close to level when sitting


Honestly it should probably come up a bit as the ground clearance isn't very forgiving.
