Default Reinforcement plate removal

I searched and did not find a clear answer.

Is it fine to:

A: Have the car on ramps with weight on the front wheels and remove the reinforcement plate.

b: Have only the front end of the car on jacks and remove the reinforcement plate.

..... with the idea in mind of not screwing up the alignment.

Thanks boys.

A. Yes, it's fine

B. Yes, it's fine.

The reinforcement plate is just a reinforcement plate it has nothing to do with your alignment.

Thanks, just the answer I was looking for. I plan on using ramps when removing this.

Actually it does, it's considered a structural component of the suspension which is why bmw recommends an alignment anytime it's removed.

Now to be realistic this isn't necessary at all, I've taken that plate off 20x and never had a problem. The only time might actually have a problem is if you somehow removed it with the chassis loaded (ie only jacked up drivers side) but to be honest I doubt the bolt holes would even line up if you actually managed to get the plate off with the car up like that.

You're fine with either way you have planned.

BTW BMW also recommends the bolts are replaced each time it's removed but that's really not necessary either.

Not at all, its not a piece typically removed. It is the silver aluminum plate on the bottom of the car that runs under the engine connecting the suspension. It's right behind the engine splash shield.

I've taken it off a million times in many different ways and bolts always line up perfect.
