So I've had my H&R Spacers (12mm/15mm) on for about 2 weeks now and I'm a little concerned about some vibration I'm having. I used the best practices to install. Cleaned off hubs good w/ wire brushes, applied anti-seize and longer bolts.
I can definitely tell a difference in vibration between 78-85mph on the highway. This is the flow of traffic in Atlanta before anyone tells me to slow down
Is this just something you have to live with when using spacers or do I need to try and re-install or something?
