I went through your build thread and found two things that can help you in the long run. In photos, I saw you have wheel spacers installed. Wheel spacers are very dangerous, and it is also not good for the geometry of your car's suspension. Wheel spacers have huge effect on your car's MPG, and god forbid if these break while you are driving in high speed, can put your life and life of the people around you in danger. Spacers put extra load on your car's engine also.
Sometimes the surface between the wheel spacers and the hub gets rusty and will throw off your wheel balance. Second thing I noticed is that you mentioned, you filled up your slow leaking tire with slime. Slime is good for only a short period of time, Once, I filled up my car's tire with slime, and it started getting vibration at certain speed. I took my car to a tire shop, and they told me that slime is the cause of vibration. Slime can also throw off your wheel balance. Because the liquid inside the tire can move from one side to other side.
In short, for your safety and safety of others, get rid of wheel spacers. You will feel the difference immediately after you drive your car.
