I have an e93 335i with m sport suspension package and 193 wheels and the ride is insanely rough, even on smooth roads it feels like im riding a skateboard, ive only had the car for about 5000 miles and the previous owner changed all the shocks 25k miles ago, is this just how the car rides in general? What could be causing this, the shocks were changed at a super reputable shop so I doubt they messed up the install, could worn bump stops be causing this? any advice is welcome, if this is just a characteristic of the suspension with the bigger wheels and thinner tires, what should I change to smooth the ride out a bit?
P.S. I dont have run flats on the car
