Set of self-adhesive foam strips of dimensions 13x155mm (W x L) and thickness 1.5, 3.0, and 5.0 mm. The set makes it easy to get the aerodynamics of your touring car front end dialed in. Filling the gap between the body and bumper keeps the body from deforming at high speeds and prevents the body from touching the track surface. You will also achieve faster top speeds with less aerodynamic loss.
