The vibrations that you are feeling that come and go is from the road surface. Different type of surfaces will produce different vibrations. Mine on grooved concrete is terrible. Smooth concrete is better. Fresh blacktop is great. |
But it didn’t do it before, same roads / interstate I drive everyday to / from work. Only started doing it recently.

I will check run-out when I can! But if it is a warped rotor I’m not getting them cut or anything. Just deal with it for a couple more months and get new rotors + pads!
I also went ahead and got some hub rings (aluminum) heard they’re better than the poly carb kind due to poly carbs melting. Not to say that’s it but figured it’s worth a shot. My aftermarket wheels don’t have them and it definitely doesn’t sit properly when the wheel is just sitting on lugs. It fixes a little but no way it can be 100% perfect even when torqued with that gap there. So I will see if that helps. Wheels are 73.1 and hub is 66.1 so I got the 73.1 to 66.1 should be here this weekend / Monday! If that doesn’t help. Then I’ll go into checking rotors / brake system more !
