Poly Bushings, questions....

Looking to do a pretty comprehensive bushing upgrade soon. In my research I can find some pretty wild price differences. The cheapest guy says theirs are as good as anyone else's, and the people who charge more all say theirs are better than anyone else's, typical advertising.



I get that in anything there can be manufacturing techniques that differ, as well as material and component quality and composition, that effect the final product. What about Poly bushings?



Anyone ever had bad experiences with cheaper bushings vs mid priced, vs high priced? I'm assuming longevity and durability would be the focus here?



I'll be using Hendrix offsets on the differential, figured I'd go ahead and lower the car while I have it in the air and apart. Anyone else offer an offset diff bushing I should look at? Maybe as part of a larger kit?



Thanks

A lot of it has to do with fit and finish and the quality of the material used. I think you will find that BMR is popular because it is a quality product.
Will the cheaper ones work, most likely, but it's a risk that can be mitigated by just buying from a well known brand like BMR.

Poly bushings are not always an upgrade

Rusty,

There are several factors to take into account when choosing bushings. The first would be the quality of the manufacture. The other would be the application that the bushings are using them for. Street or Track as an example. This is where the durometer comes into play. The durometer is how stiff a bushing is. Factory rubber bushings have a very low durometer, whereas poly street bushing would be around 68, and poly track/ race bushing would be 95. So take the Hendrix bushings, even though they are hard (we have not tested them, but they feel about 90) they are what you want so you keep the diff from moving around. Hope this helps.

My car is lowered on coilovers. I have poly diff bushings, cradle bushings and all of my rear control arms are poly. I replaced my entire front suspension with all new arms with Moog arms with stock rubber bushings. you will definitely get some NVH with Poly bushings in the rear, but after a few days I don't even notice the noise anymore, it just sounds normal to me. So far I have had 0 issues with my setup after going Poly bushings. Car feels better, handles better and I can put down my hp #'s with almost no tire spin. She only cuts loose at about 5000-6000 rpms in first gear on a hot day and after that she just hooks and books.
