Doing solid subframe/diff bushings. What else should I do while subframe is out?
As title states, going to do solid subframe & solid diff mounts soon. What else should I do with the subframe down since its a PITA to remove? Car has 65k miles DCT. Changed diff fluid last year. Is there even anything you can do? Thanks.

^ +1. And I think 2 of the 6 brake lines are easier to swap (to SS) now as well.
I am curious what other bushings and joints are worth replacing at that point. I reinforced my subframe (plates + AKG 95A bushings) at 65K on my E46 and did the CSB, guibo, RTABs, etc. at the same time. Other than the RTABs, the parts all looked pretty good. And I did not notice much of a difference with the AKG subframe mounts. I really want to feel solid subframe mounts on the E9x before committing to the work. On the E46, it was a no brainer since the reinforcements are needed. On the E9x, it's just a matter of stiffening up the chassis, but the work is no less. I can see this being worthwhile at 80K+ when other components need a refresh, but going through the work for subframe mounts alone on a low-mile car is tough to rationalize without feeling it. |

I am okay with the AKG 95A diff bushings in my E46, but wouldn't want anything louder. But that car has Dinan exhaust and is just built up a little more, so the subtle whine is quite fine. But in the E90, I don't want any whine. Diff bushings will stay stock since people report whine even with Powerflex purple (the softest of poly). Maybe I'd welcome the trade off with a 6MT, but there's less to gain with a DCT. |

Right now the stupid R888R will drown out almost all the noise on account of the racket they make, however, I can hear the diff and with more human-friendly tires like the RE71 it's going to be annoying I went with whatever powerflex bushings people recommend If this were my daily driver I'd be pissed |

I honestly never noticed any issues with the oem subframe bushings but as the car sees 40 track days a year I thought it was best to increase rigidity |

That's a lot of track time indeed, and allows you justify far more than I can.
I do think solid subframe and stock diff mounts is a sweet setup - slightly tighter, no whine - it's just whether or not the $1000 in parts/labor is worth it on mildly modified street car. |

Or look at it this way: I'm not going to do them to my secondary track car which is the E92 |
