Pair of self-adhesive foam strips of proportions 13x155mm (W x L) and thickness 1.5, 3.0, and 5.0 mm. The set allows you getting the aerodynamics of your touring automobile front end dialed in. Filling the gap between the body and bumper keeps the body from deforming at high rates and prevents the body from pressing the track area. You will also attain faster top speeds with less aerodynamic loss.
