99SlvrC43

Ok, while driving at any speed above 80MPH my 98 C43 shakes/vibrates too much. I'd like to know why? Its not even fun or safe feeling to be going over 80 for more than a few seconds. I feel I have no control over the car.

Is it wheel balancing? (did it about 8k miles ago or 14-16 months ago)
Shocks? (the car has Brabus lowering springs for 16K miles now)
Tires? They are match set but are about done on tread wear.
Something else????

I figure its time to spend some $$ on it and fix the problem. So please help

reco

does the vibration comes from front or rear part of the car? if tires are well ballanced means is the time to change the rubber. do it in a prof garrage and after the new one are on ask to be checked at very hight speed. good luck

The shakes may not be related to your suspension/wheels necessarily. Depending on what kind of shakes they could potentially be related to the engine/intake/exhaust. Any more specifics on where the shakes are coming from, how strong, etc?

B/c I dont drive it much I dont recall the last time I felt it. But I know I never felt it this much (intensity) before.

String whl doesnt shake. its not when braking. Just going over 80 brings it out. And it seems to be from the rear but There is no way I can be certain. I should retract that statement since the C43 is already noise from the rear (the infamous rear deck rattle) So I really! hear that while it shakes.
