I'm getting my rear subframe bushings installed next week, and I'm wondering if there are any other bushings, or anything else, that I should have replaced at the same time. My car has about 110000 miles on it, and is probably all original stuff still. I've only just replaced the rear shocks and shocks mounts at about 100000 miles. Thanks for help.

Replace your rear control arm bushings also (total of 4), and look at your rear brake lines (the ones that go from the body to the rear control arms) if they have small cracks in them then replace them.....they are much easier to replace W/ the rear subframe out.'91 318is -

The shop that installed my subframe bushings, which were urethane, didn't replace the stock rear control arm bushings because he said that with the stiffer subframe bushings, the control arms will crack unless he reinforced it with some welds.
Can anybody identify with what he is saying?Comment

He's a very reputable, skilled mechanic who installed the sfb for a very reasonable price compared to other mechanics in my area. He seemed to know what he was talking about because the guy he works with is way into performance handling stuff and he cautioned running the urethane bushings in danger of the rest of the subframe/control arms interacting... inbalanced, or whatever he said. I need to familiarize myself with the rear suspension a little better i guess...Comment

imbalanced? what does that mean?
it's very simple. replacing the subframe bushings with urethane won't make it crack. neither would the trailing arms; they're still bushings, not steel rods! I would much rather have a working poly bushing than a worn out and loose stock one any day. Worn out parts are probably more likely to cause damage to your suspension than stiffer bushings.Comment

I'm driving around with urethane subframe bushings, and stock rubber trailing arm bushings, and theres no problem with their "interaction". Feels great, solid and planted.
I just think the mechanic is misinformed about this. He's not necessarily lying to ya.Comment

I NEED new rsf bushings asap, I can feel the play in the rear end under heavy acceleration.

i love my new urethane bushings. They are that Bavauto set that I got for pretty cheap. Anybody know if they are intended for a street use or track use? Anyway, I think it fixed any rear alignment issues because my car seems to track better. It certainly handles much better, pulls through the corners much tighter, and much of the clunking/bucking is gone. Before it felt like my back end was going to tip right off the frame. I really regret not lowering it now. Hopefully soon that will happen, along with some upgraded sways. Having trouble with power steering stuff right now though... Great. Anyway, thanks for the help guysComment

those are K-Mac eccentric / adjustable bushings, they help me correct excessive negative camber after I lowered my ride.
they come with a tool to remove old bushings, it's pretty simple work, new ones just slide in by hand.
pretty happy with them, they work just as advertised.Comment

what is the ride quality like with those?Comment
