My daily drive is an E90 320i 6MT and it's rather firm and solid on the road, despite having standard suspension running on 16" RFTs. My Z3 seems remarkably soft and less sporty by comparison. Wondering if I need to replace suspension bushings - has anyone done so on their Z3 and what was the result? Worth the effort? My bushes do not seem worn in any way after a visual inspection but I suspect after 15 years they will be worn. Rubber doesn't last forever.
