Installed H&R lowering springs 29378.1

[X5only]

I installed the H&R lowering springs 29378.1. It's for air ride rear suspension only and consists of 2 springs for lowering the front and 2 links for lowering air ride suspension on the rear. My problem is that those two links are supposed to be adjusted to 65mm in length per H&R instructions manual. I also called them to confirm. But that makes the links longer than the factory ones. Rear ride height is now at 29 1/2 (749mm).

Does anyone have these installed on their single-axle air spring sports suspension? What is your rear ride height? Should I just adjust the links to make them short or install back the factory ones? The factory ones are shorter than the H&R links even when shortened to max.
