I'm not sure if it just me or not but most of the time I tried to avoid the potholes around here. However sometimes my ride could feel little bouncy when hit small potholes or sometime can hear big thud when hitting big bump, going avg 40mph on street.

What could causes this? I'm not running stock shocks just Coilovers that it. I hope it not my blown coilovers if it is ... well ****. I just hope it the just conditions on the road this season...

 

If you mean bouncy like those ricers that look like they hit the switches just by shifting, then ya, the shocks are blown.
The car shouldn't actually spring back up and bounce.





Can you hit the brakes and accelerate and make the car do this?

 

 

Bounce isn't good.
Sounds like new suspension time, but maybe you just need to adjust your coilovers.
