Straight from SubiSpeed

We see this kit most on track builds and on cars that want the full aero look in one purchase. Dry-fit every piece before paint or final mounting, since several pieces have to line up with each other. It pairs well with a rear wing from the same lineup to keep front and rear aero balanced.
