Anyone know where I can buy an upgrade poly bushes for me diff
Not recommended unless it’s a dedicated race / track car.
klan explain why ??
General consensus is that they will clunk too much on a road car. Better off with new bushings (the entire rear cover) from BMW, and the revised bolts.
Get OEM, when you get the part, you will see its a proper solid bit of kit anyway - I see no need to use a poly bush.
OEM diff bushes were the recommendation to me too, and it made a massive difference replacing mine after 57,000 miles.
OEM is best for road car, poly are noisy as hell.
I have high quality AKG poly for my track car. Stay away from powerflex. I had one fail with only 2000 miles.
Poly diff mounts transmit huge amounts of noise, more than any other bush replacement on the car.
Unless you are ok with that, don't do it.
As above, stock to oem!!
I have upgraded my e46 to polybushes and couldnt tell the difference in noise. That was sub frame and diff.
