Hello all, might be a long shot but does anyone have a front sway bar reinforcement plate they haven't installed yet? If so, I'd greatly appreciate some measured dimensions, primarily hole locations and overall plate sizing. I was looking at the MSW plates (https://www.moreheadspeedworks.com/product/e46-z4-front-anti-roll-bar-reinforcements/) since they also have drain holes, but any plate will do. I'm looking for these dimensions to make my own and with my car in winter storage I can't take measurements until it comes back out. Thanks!

I have a Hotchkis kit that I haven't installed yet. Lmk if you want pics/dims of the plates that come with it.

Appreciate the offer, had a look at some of the install videos and it looks like the studs sit in the middle of the slots so unfortunately those plate dimensions won't give me a whole lot more than I already know. Found a post on zpost where the studs are M8 with 90 mm spacing, I may try to guesstimate overall plate size and drain hole locations from that skewed pic I posted

Alright, finally got around to getting a set waterjet - bear in mind that I made them before I could actually access my car, so the holes were a tad off. If you want to make your own the below dimensions are of the original plate for reference, before filing:

Essentially the holes for the studs were set to 90 mm apart, but the ones in my car were maybe 1-2 mm wider than that. The holes for drainage had to be filed towards the holes for the studs, maybe around 4-5 mm.

Hope this comes in useful for someone wanting to fab their own as well.
