Question about spacer for ground controls and ix bilsteins hds

[Brezzi]

Hey guys,

Recently cut 2'' out of my front strut tubes and am going to run ix Bilstein HDs. I know this a pretty popular set up. My question is how big of a spacer are you that have this set up using? I cut spacers whatever the length the kid who put the vid up on YouTube used but they are too tall. Before I redo this a thousand times I wanted to see if anyone or multiple parties had a definitive answer.

Thanks!

iX bilsteins are 85mm shorter than 325i etc Bilsteins, so 85mm less what you removed
