Installing a rear sway bar

Found these directions for a E90:
https://s3-us-west-2.amazonaws.com/f...ons/22834R.pdf

According to the directions, you can remove the rear subframe bolts and loosen the front subframe bolts. I'd rather not disconnect my brake lines since I have an autocross event on Saturday and I may be doing this more than once since I'm going to try my 15mm bar first, and if I don't get enough rotation, will jump to a 20mm one.

Any hints or suggestions before I start?

It's not much fun, getting the stock bar out is really easy because it's so flexible. A 15mm bar might not be too hard to put in but my M3 rear took a lot of creativity to snake it through and out the other side.

I loosened all bolts, removed the big cup washers for the bolts to get the subframe down a little further. If I did it again I'd disconnect the brake lines for as much extra space as I could get. Definitely disconnect the wishbones and I ended up unbolting the guide rods too.

I did a fair amount of "rocking" the subframe as I fed the bar through. My car has the stainless fuel filler pipe, that made the passenger side a bigger pain to deal with, but I went from driver to passenger side to get it in.

I also just did an M3 rear bar like spidertri. I was going M3 rear arms at the same time. I can't imagine getting a new, bigger, bar in with those arms in place. I lowered the subframe but didn't disconnect any brake lines. It's a pain to fish the new one through, but it can be done.

People here overexaggerate. The last time I did a rear bar on one of these cars, it was <2 hours all in, and I'm not a fast wrench. Put a jack under the diff/subframe, remove the four mounting bolts and slowly lower it down until you have decent access then just wiggle it out from the side.

Did you undo the brake lines or anything else?
