replacement radius arm bushes

satz · 09-18-2015, 01:27 AM

hi all

I took my 09 335i sedan to a suspension/steering specialist for a wheel alignment. However they said that I need to replace the radius control arm bushes on the front suspension.

They have offered to do it with nolathane ones.

I've emailed the only BMW dealer here, and they've quote less (!) to do the job. Presume they'll use the stock rubber bushes.

Which do you think I should go with? Do non-rubber bushes in the radius arm affect NVH?

cheers

Polyurethane is not recommended unless track car. They will not last as long as OEm rubber bushings on top NVH. I recommend replacing the whole arm with OEM M3 counter part. Both upper and lower. Great upgrade! Probably cheaper too.

You also have HD version of the none M bushings as an option.
