Avid A800 long arm roll centre shims
Avid have introduced their new carbon fibre roll centre shims for long arm equipped Awesomatix A800 touring cars. The shims are designed to be put on without unscrewing the ball from the screw, and they are marked with notches for quick size notification. They can be used both front and rear and are available as 2-each or 4-each packs of 0.5mm, 1.0mm, 2.0mm, and 3.0mm shims.
