E90 rear subframe bushes

Dan-danGT · 08-31-2015, 08:56 AM

Hi everyone, I have a terrible self steering sensation from my e90 rear end. I'm sure I have narrowed it down to the rear sunbframe bushes. Now my problem, Turner motorsport do a kit @ $500 which is only for 4 bushes. However powerflex do two different bush kits, has anyone ever bought any or have any other suggestions? I could buy genuine but would rather upgrade if possible. As I do drive fast and like to have a slide every now and again

are you sure it's not rear wheel alignment that is causing the issue?

Assuming it is the sub-frame bushes, you can fit M3 bushes, stiffer than standard, hardly any increase in road noise.

Great improvement, even when standard ones are OK.

Might look into that as well, I had geometry checked it was all ok apparently. They did adjust tracking which might indicate rear was out slightly

I had my alignment looked at recently (having had the car almost 2 years, I should have done it earlier) and the toe on the rear was miles out.

This was causing lots of rear steering under power, pulling to the left when accelerating and moving to the right when lifting off.

Alignment (and two new rear tyres to replace the ones that had worn through at the bottom of the sidewall) seems to have cured it.

I am running the M3 bushes and would be tempted to upgrade to the M3 rear arms as well, if I knew the likely effect on NVH.

Whiteline bushes are awesome although a little firm for most, love mine though.

Thanks for the info sparky, I will look into it. I don't mind firm
