My 5 year old Macan (diesel) failed its MOT due to worn bushings (specifically the right hand compliance bush). It has a Porsche warranty, and had a clean bill of health 1500 miles ago when it had its warranty check. Alas the OPC are saying bush replacement won't be covered by the warranty, although I've asked Porsche UK to help.
All that is very diasppointing. However, given thr apparently high cost of bushing replacement (they have to be done in pairs etc), and the prospect of possible replacement every few years, I was thinking about replacement using polyuerethane rather than rubber. PU have a long lifetime, are easy to install and might tighten up the handling anyway.
Do people have any experience with PU bushings ? Will the ride be too harsh, and the excess forces passed on to other suspension components to their detriment ? The car has air suspension and PASM and has to survive Hereforshsire potholed lanes.
Thanks !

From my own experience with other cars, poly bushes are plainly unforgiving. They can set a car for great handling in the twisty bits, and point and shoot becomes a reality, but- the ride in a Macan is likely to become crashy to the point of being v uncomfortable. For the Macan, equipped with pasm et al poly bushes could risk ruining the handling of the car with its complex, and v useful suspension/handling systems, all imho of course
. Poly bushes in a mid engined lightweight sports car are a hoot, believe me
but in a 2 tonne 4wd pedigree SUV? Well I wouldn’t..... hth

Yes - very impressed with Cotswold Porsche Specialists https://www.cotswoldspecialists.co.uk/. They are lined up for this. As you say, a lot cheaper than the OPC !
