Stabilizer link bushing (most probably need replacing)
Lower arm Suspension bushings ( most probably need replacing)
Engine mounting (check first, sometimes not all 3 mountings need replacing)

If you lowered the car and/or change bigger rims, then more vibration and bumpiness, even if all bushings and mountings are replaced.

Wah...I hope you're not over exaggerating. Road vibrations shouldn't be that pronounced/obvious until it affects the A-Pillar and/or roof of a vehicle - unless of course if the chassis of said vehicle had been compromised.

Anyhow, based upon your following description (vibrations being felt through the steering wheel), I would recommend for you to get the vehicle's undercarriage checked.

Wear and tear parts such as steering rack-end and tie-rods would be a couple of obvious ones, besides absorber bearings and lower arm bushes and ball joints.

P/S - Understand that you've just had your absorbers replaced, hence I've not listed it as one of the obvious wear and tear items to be checked. However, there may be a remote chance that the newly replaced absorbers could be faulty as well - so, no harm in getting that checked too.

Do take note that non-stock absorbers (e.g. after-market shocks) that has differing rebound rates than that of the vehicle's factory suspension settings could also result in pronounced vibrations.
