Net effect?

 

this is good news!

 

Not used to hear people calling "bushes" in the U.S.
Maybe it's a common thing in UK and other EU countries.

Wonder how this brand "bushes" are better than original ones in the F56?

 

likely polyurethane, therefore stiffer than OEM and will not degrade as quickly as rubber. Their purpose is to stiffen up flex points giving very crisp handling characteristics.

 

No experience with the brand in question and but I had (and still have) poly bushings in my other daily drivers (Acura RSX and 4Runner).

My opinion: Fine on suspension parts but will get creaky if not installed with the proper lube.

For motor or tranny mounts, you could not pay me enough money to have poly inserts again. Vibes are terrible and also, depending on the durometer poly they use, expect to have to replace them every few years. Poly is very resistant to environmental chemicals but unlike rubber, is unable to return to its form once heavily deformed over a period of time. Never had a poly motor mount bushing that didn't egg-out sooner or later.

IMO, you only need to think about these on really old vehicles with rotten bushings. Not for a new car. Just my 2-cents.

 

Wow, thanks for the education!

I thought poly bushings are far superior over rubber ones on EVERY factor...

 

They are not available in the US yet, but we will have them as soon as they are available.

 

The diagram showing locations for the bushes is nice in the first post.
