Weird vibration/rattling noise

[sien]

hey guys. i had a fun cruise last night but i got some weird shyt that i need some help/clarification about.

firstly, my car is lowered with king springs low for front and back, falken rt615s all round. other than that, pretty much stock to the handling part.

anyways, i was going fast around corners, and every time the road is uneven, my car seems to vibrate really hard and its really loud and annoying. i can feel the feedback on my steering wheel and its not smth i want. is it due to the stock suspension that are too soft or what? cuz this noise is really scary and it happens whenever i go fast around uneven roads.

just wanna get some information on whats going on with my car if you guys ever experienced it before.

cheers, Nick

You need a wheel alignment to begin with, also check springs are still captive on your struts - I'm not sure if it's just superlows that are too short for the strut.

Those tyres you use are slicks and have hard side walls. Being lowered as well adds to the feedback you will feel via the steering wheel on normal roads.

The "vibration" you feel are road noises and your tyres going over stones and gravel and loose particles on the road. Loud yes but normal.

Not to mention the Stivo are known for noises as I too have panels vibrating and the likes at a certain RPM.

So in short, lowered + tyres with hard side wall (especially slicks) will add to your "discomfort" for everyday driving.
