no they ride really good for the amount they lower the car, i love mine

 

The HHR on goldlines rides very smooth. I was worried about the ride when I installed the goldlines, even more so when I installed my 18's. But I'm impressed with the ride and sometimes I forget that it's lowered with low-profile tires...Now you do have to avoid certain potholes and bumpy roads, but I think you have to do that anyway
