[Route 16]

For an E90 328 at 106k miles. I'll be upgrading to F/R M3 TRW suspension bits. Other than that, is there anything else? Is that considered covering all of the bushings for the car? My coilovers are still okay. Will do OEM transmission/engine mounts, Lemforder tie rod set. I'm just extending the life of my car. Not really for any performance gain but still looking forward to getting the car "better" than what it was before.

Front M3 control arms will yield a noticeable improvement in steering responsiveness and precision but you won't notice anything from the rear upper M4 links so don't waste your money.

The trailing link and toe arm (track arm) bushings are some others that could be replaced along with the lower camber arm (spring arm) inner and outer bushings but these may not be worn enough to spend the money one, have a competent tech eval their condition before dropping the money on the parts.

Subframe and diff bushings as well as the Guibo ought to be fine at this mileage but I'm sure someone will correct me otherwise.

Quick question, has anyone changed the toe arm from the m3 onto the 335i and can it be done? Are they a swop over?

The M3 part is longer, won't fit. And it's the bushings that matter and they're the same so no improvement to be had there.
