Added sealed monobals to car... don't feel much difference

Had the vac monoballs put on, both upper and lower arms on both sides. From what I read, people were ranting and raving about them....

The only thing I've noticed is increased NVH... steering feels pretty much the same

Is it possible that bc I have thp, and therefor vss... that the dead in center feel of the vss, is making me not feel the better turn in feel? I've also been doing mainly city driving

Annoyed bc now I feel like I wasted $2k on parts + labor... to have no improvement, yet added nvh

Not going to do much for steering feel. Its to tighten up the suspension response sloppiness on the hard fast turns useful on a track.

I did something similar a while ago. Under "normal" street driving conditions, the car won't work any better for you, but when you start driving "enthusiastically", the steering stays solid, where it used to get mushy. This is the gain from adding monoballs to the suspension.

If you're not running on the track, or driving "enthusiastically" on the street, monoballs probably aren't the best solution, primarily due to the NVH they bring with them.

I've got the VAC monoball upper and lower control arms on my F30 335ix. It's a tremendous improvement in the vague F30 steering, especially when you switch to Sport mode. So much more precise than stock. Night and day!
