I have beads in an older vehicle and I remember them working well. It has been a few years since I have driven the vehicle.
I had a pair of centramatics on my pickup that went bad. The company warranted them with a new set. I put these on the truck and found the truck drove smoother without the centramatics.
If you decide to go the centramatics route make sure you hear the bb's make noise when the wheel turns.
