2025 RCSB UMI lowering kit w/ VAS upper control arms question

[UmbraRCSB]

The shop installing the control arms said the 1/2 drill bit slides right through. I was under the impression these were ready to install right out of the box. But also, is it possible there is a difference between 21-24 and 25?

To pass through.....the spindle ? I'd want something a little more precise if I was drilling / enlarging a hole on the spindle. Grabbing a drill and "hogging out" a hole seems super sketchy at best for a precision machined part.

Not to mention, I finally got an email back from them... And apparently the 1/2" was a typo. It's supposed to be 9/16. And the advert when I bought them, said ready to install out of the box.
