Jack up my M535i
Jack up my M535i
I was able to buy a set of bbs style 5, and want to mount it under my M535i. What is the best and safest way to jack it up with a garage jack? I don't want to jack it up on the original jacking points because I'm afraid I will damage my sills. What is a hard and good jack point?

Re: Jack up my M535i
Hallo!
Good news! this has been discussed much in the past here, and one member has made and sells pads designed for such.

Re: Jack up my M535i
Thanks for the tip! Certainly a good solution. Would like to buy them, but they are sold out I see. Can the car still be lifted somewhere on the chassis?
Re: Jack up my M535i
If you have a Mtech body kit (which I guess you have since it's a M535i) you'll have to use those pads but on the jacking points added with the kit, not on the sill.
Personally, I jack the car up from the subframes (either the front or the rear one)

Or
Get a piece of wood and go on the frame rail for the front. Jack up from the diff in the back and you can get both rear wheels in the air (use a wheel chalk)
Re: Jack up my M535i
Couldn't agree more with this. You dont need anything fancy, just raise it up until the wheel starts dragging inward a bit and then lower it a touch, so the wheel cant turn, and undo the wheel studs, then raise it and remove the wheel. Put the new wheel on, do up the studs evenly, lower it a bit until its just on the ground, then tighten it using a torque wrench, not a burp gun. The most important thing is to get the studs torque even, so the wheel runs true.LeiseyJr wrote: ↑May 06, 2021 11:30 AMhttps://www.racegerman.com/product-page/e30-jack-padAlberto89 wrote: ↑May 06, 2021 8:49 AM I was able to buy a set of bbs style 5, and want to mount it under my M535i.

Re: Jack up my M535i
Hi,
That's right. M package. I know where the normal jack points are. Thanks for thinking along. So subframe is allowed?

It will not harm the mounting points of the differential?LeiseyJr wrote: ↑May 06, 2021 11:30 AMhttps://www.racegerman.com/product-page/e30-jack-padAlberto89 wrote: ↑May 06, 2021 8:49 AM I was able to buy a set of bbs style 5, and want to mount it under my M535i.

Re: Jack up my M535i
Given that I've had a couple of diff mounts break, I use the subframe in front of the diff rather than the diff itself. Jacking under the diff won't hurt it, but it might damage the diff mount.Alberto89 wrote: ↑May 06, 2021 3:08 PMIt will not harm the mounting points of the differential?LeiseyJr wrote: ↑May 06, 2021 11:30 AMhttps://www.racegerman.com/product-page/e30-jack-padAlberto89 wrote: ↑May 06, 2021 8:49 AM I was able to buy a set of bbs style 5, and want to mount it under my M535i.

Re: Jack up my M535i
The subframe is fragile and easily damaged. If the diff mount fails when jacking under the diff (which distributes the load anyway), then it was going to fail anyway during day to day use. I suppose one should philosophically look at this as pre-empting that inevitable failure.Mike W. wrote: ↑May 06, 2021 3:19 PMGiven that I've had a couple of diff mounts break, I use the subframe in front of the diff rather than the diff itself.

Re: Jack up my M535i
I respectfully, but vehemently disagree. The subframe is pretty beefy there in the middle, it has to be to withstand the torquing action of the drivetrain.JohnH wrote: ↑May 06, 2021 11:08 PM

This are the same for the e28?LeiseyJr wrote: ↑May 06, 2021 11:30 AMhttps://www.racegerman.com/product-page/e30-jack-padAlberto89 wrote: ↑May 06, 2021 8:49 AM I was able to buy a set of bbs style 5, and want to mount it under my M535i.

Re: Jack up my M535i
The subframe isnt a beefy structure at all. Its hollow and made of 1.5mm steel or so and is very easily dented by by a badly placed jack or jack stand. The strongest part of the structure is the section that bolts to the diff, so putting a jack under the diff is actually using the subframes attributes and not its weaknesses. As I said, if the rear mount fails because of jacking the diff, it was going to fail anyway.Mike W. wrote: ↑May 06, 2021 11:47 PMI respectfully, but vehemently disagree.

Re: Jack up my M535i
One wheel at a time
Front--frame rails
Rear--subframe bushings just in front of the wheel
Both wheels on the end
Front--subframe behind oil pan
Rear--diff
I will not use the 'jack points' anymore. These are flimsy sheet metal designed to buckle under the weight of the car on a jack unless the load is spread a good foot or two along the structure.

Re: Jack up my M535i
I have decided not to use them. I'd rather go to a garage where they could lift hydraulically. Thank you all for the tips.

Re: Jack up my M535i
Many garages put the lift arms at the jacking points and damage the car. Be demanding that the arm lift the frame rails up front and the subframe bushing locations in back or some other part of the car that will support the weight.
Last place I would go is some shop that don't know shit about these cars.
