HI GUYS

i have a 2006 323i m sport with 17in wheels and bridgestone RFTS 79000kms
she has 2007 325i m sport with same 17in wheels but conti RFTS 75000kms
both have new tyres
tyre pressures are at recommended
alignment is within spec

her suspension seems firm and well controlled but a lot more comfortable than mine, just drove it and it seems like a new car vs mine which feels a firm and controlled but you feel every bump and speed hump much worse so hence very uncomfortable!

what do you think it is ? the tyres or do i need new springs ? shocks or bushes ?

thanx for your time

If I had to take a shot in the dark, I would say it's probably that your bushings are more worn.

i am leaning to bushings as well,
i will ask them to change them , along with shocks at the next service interval which is for brakes anyway

thanx

The only reason I say bushings is that yours are a year older and age has a big effect on bushings as well as miles. FWIW I just changed out my front sway bar, and in the process switched bushings as well. I changed the bar from a harder UUC to more lenient M3, and the front actually tightened up in comparison. The only explanation I have is the new bushings.

Probably just the Bridgstones.

They seem regarded as about as hard as they get in the RFT ranges!
