polyurethane bushings
 

Is these bushings good to used ? is there a write up on how to install on upper and lower control

I love them, jut had a set of Powerflex thrust arm bushings installed back in October, do a search, you'll find more info that way.

How have they been treating you? Do you get squeaks or anything like that when it gets colder?

You must be a glutton for punishment going with hard bushing around the Bronx NY area.

Ive had the purple urethane bushing in for a couple months now. The ride quality hasn't change much. I highly recommend them.

Google E53 tension arms for write ups. I had a shop install them for $80.

I would recommend them for almost everywhere EXCEPT the rust belt states, the roads are trashed in the NY area.

..the more of a reason to go urethane IMO. You won't go replacing the tension struts every 20K.

Harder bushings transfer more shock to the chassis/subframe, not a good if the roads you drive are trashed. Have you ever driven over the Whitestone Bridge in March? There are 2 inch thick steel plates that the road crews have placed over the missing sections of roadway, pothole you can look down thru and see the river below :wow:, all this at 60 mph. This is a 2 1/2 ton truck with uni-body construction, I would expect metal fatigue and possibly subframe damage.

These aren't metal. Theyll still give.

I know what they are, I've used them on my tracked ZR1 Vette and Viper. You never answered the question, have you seen the roads that the OP is driving on???? There have been discussions on Bimmerforums about the poly bushings causing damage to the chassis of BMWs.

Guys if you have never been to NYC, or anywhere around here, you really don't understand the conditions of the roads we drive on.

At least once a year I replace;
1. At least one tire. At least. Due to blow out, bubble, tear, etc...
2. Bent rim.
3. Occasionally I hit such a huge hole that I split a rim.

I had poly bushings on my Lexus, it took it fine except they started to squeal like a pig about a year into it. Constant re-greasing. Nothing ever fell off of it due to the bushings, but you never know with these BMWs.

To each their own... I have stiff coilover suspension on my S2000 and drive it around San Francisco. I also visited all over NYC last summer and have a good idea of how the streets look.

there is another in between option: go with Meyle which are better than stock but not not as hard as the power flex.

If you have not driven Brooklyn, Bronx, Queens in March you have NO idea how bad these roads get!!! :rolleyes:

Oh and the belt is under construction till 2016. You do not even understand the lengths I go to just to avoid it.

NEVER heard/seen that with these powerflexes (or even dinan steel monoball mounts) on E38/9s or E53s. Maybe on E36/46s....but not on the e53

thanks for the feed back .the whitestone bridge is nice and smooth,were i lived the roads are decent

I have Polly in the front and the rear of my 4.6 its great

just do not spray Polly with wd40 it eats the bushing use the lube it came with

Which bushings do you have. You have a link. Thanks.
