H&R rear sway bar help
Ok just a small question- didn't want to post in the general section.
I bought a used rear H&R non-m sway bar for the xi. Upon closer inspection, it looks like i got 20mm OEM BMW rear sway bar bushings, instead of the 21mm bushings that come with the H&R bar new.
Can I use the 20mm bushings on a 21mm bar? Or is that a complete no-go? Is it safe to shave 1/2mm from the inside diameter of the bushings?
If not, should I go with the 21.5mm M3 bushings?
Thanks guys- I have no experience with sways and I was hoping to get them on tomorrow because I'll have a nice place to test the new setup on Sunday. Otherwise I guess I'll have to order new bushings from H&R.
