Probably similar. Ours is a one piece design with no welding for longer life. Plus this one comes from BMS so you're supporting us and the forum...

Awesome to see the mass differences in the rear suspension of the 1M vs a regular 1 series. Thank you for the picture, no it will not fit

It should fit no issues, I don't recall any undercarriage under the rear end. Got any pictures for me to verify for you?

I am going to assume no E60 535xi fitment? Would it even be beneficial? Thanks.

Curious,did you guys come up with the dimensions?would their be a issue with the bottom bend that connects to rear diff?heard this from the other guy that makes these to before bms did and that the bottom where it tapers should be wider.bms brace is a little cheaper but worried about that.

This thing will not break though and fits perfect, it's bent and cut to the exact dimensions. This is much stronger than the welded pieces. I've gone through 2 of them on my 800whp car. This one has no weak points, it is 1/4" steel laser cut and bent on a 40 ton CNC press brake that barely bent it. Imagine if 40 tons could barely bend that what force you need to brake it.

Oh dang that's a nice 1m!

Im pretty sure it's because the diff has cooling fins and is a different design there won't be a place to bolt the brace onto it. I wish there was an option for us guys with M diffs.

What happens if a bushing fails while this is in place ? Would it risk cracking the subframe its bolted to or the diff casing itself ??? Bushings are used for a reason, this deletes it out of the equation.

A 40 ton press would bent it like butter. I can bend (and do so on a daily basis), 1/4" steel with a bench vise and vise grips with a small piece of tubing for leverage. Its a nice piece, the product will sell itself. On another note, any others that are welded, if done CORRECTLY will be just as strong. I reinforce suspensions ( make custom parts as well) and car frames on a daily basis and am also certified welder for oil refineries.

It depends on the area you are actually bending, maybe his press brake is weak. I doubt it though because his 55 ton press brake that isnt CNC took some force too.

Welding has weak points comparing to a solid piece, period. We've done the testing, along with a certified aerospace welder lol... still broke. This is the best way about it to be honest.

I think Payam's point was he's broken two of them from another vendor (who he's purposely not naming to avoid a flame war), before we decided to just make our own one piece units. And the one piece units have been solid for us.
