Wheels

Most people I know use glue-on wheel weights. With stock magnesium wheels, the clip-on weights vibrate slightly, chipping paint. This than causes water penetration & damage to the magnesium. With your aluminum Etoiles, there is probably no reason to use edge weights, as they are typically only used for side-to-side balencing off-center heavy spots in tires or wheels. Try the glue-ons, more-or-less centered in the rim, and at the same time have a spin-balence done. Your tire guy will probably find that edge wts are not necessary.
