hey guys im lowered on tein street basis coils and whenever i go around 70-100 the whole car feels like its vibrating not a crazy vibration but i was wondering is it cause im lowered or something els? anyone have this problem?

 

Depends on the Road! If its Smooth Straight Road and Depends you have your 4 Wheels Balanced??
Un-balance its way more Drastic at High Speeds...

All in All being Lowered should be more Stable at High Speeds since there is less Turbulence below the Car. How old are the Coils? Even Being Coil-Overs the Strut will needs to be Rebuilt if its Done they dont Last Forever.

 

Your wheels may need to be rebalanced or you have an axle issue

 

thanks guys the coils are only a few months old they are fine but i think i need to balance my wheels thats all.

 

Did you get an alignment after lowering your it? if not your toe is off and will need to be realigned.

 

I just had to get the wheels balanced and the vibration went away

 

Often times the simplest stuff is overlooked !
Alignment and balance are very critical after lowering the suspension.
With over 10 years / 100k on the dial, it's important to check out everything for wear !
