Z4 / Z4M Track Rods

Hey all!

I'm going to be swapping the front kingpins (knuckles) and wishbones over to the Z4M set that I bought a while ago. Everything looks to be a straight swap (going to be using new Z4M coilovers at the front) with a slight increase in track width.

My only question is with the track rods. It seems the outer section (with the ball joint that connects to the kingpin/knuckle) are the same PN between Z4 and Z4M, but the inner differs. From a quick PN search on Autodoc it seems that there is only a 1-2mm difference (depending on brand) in length of this inner track rod. Can anyone confirm this? If not, do you think I'd have enough adjustment in the stock Z4 track rods to cover this swap?
 
Actually I think I just answered my own question!!

It seems a bunch of people have put non-M track rods inners on a Z4M as a cheaper/easier to source alternative and there is functionally no difference.

Going to leave this thread here instead of deleting it in case others find it with the same question.
