I have M3 subs and Turner delrin diff bushings in my car. What do you guys want to know specifically? I get deceleration whine at about 3k rpms, but it is only audible with the radio turned off.

You just need to drop the diff to make the change.

You and Tres both report a minimal increase in NVH v. a couple guys who report a noticable increase in NVH with the poly diff bushings. Since solid delrin bushings will never wear out, that's the route I'm going. Thanks.

Do they have full interior? I cannot imagine the whine is more than what I am describing with full interior.

I'll be impatiently waiting for the write-up.
Since installing my coilovers and stiffer springs I feel no movement in the rear like before, so I'm still on the fence with this upgrade.

thx, seems like this is the new hot topic here nowadays, the bushings, esp diff and subframe. i gotta tell you, working with delrin in design engineering, it does get scratched with abuse and friction, so i wonder the long term wear.

Did you feel a noticeable improvement in rear tracking/stability upon install? Was the upgrade done exclusively or in conjunction with other suspension upgrades?

From me? You'll be waiting a long time I'm not going to switch out the diff bushings this year.

Yes, they are the same.
I am not a fan of upgrading the diff mounting bushings at all on street cars since more drivetrain noise will be both felt and heard. If you can handle the increase in NVH, upgrade away. Sometimes you must draw the line between a street car and a track car, certain mods are for track only. Although some track mods are okay for the street, the service life of that part may be shorter because of the terrible roads we have. Last edited by HP Autosport; 07-28-2012 at 03:40 PM.. |

I have power flex diff bush and M3 subframe bush installed. I noticed a very little noise after the installation but it is really just because the original 335 bushes are too soft or comfy. Before I feel like I am riding a boat and now I am riding a normal car.

Did you see a pic of the rear m3 diff bushing; you said you think it's solid?
