Verus Engineering Plastic Rear Spat KitAdd the Verus Engineering Rear Spats to your Subaru BRZ or Toyota GR86 to complete the rear aerodynamics of your car. These units were designed specifically to flow with the rear bumper and our rear diffuser. Ultimately these will help tie together the rear end with our side splitters and rear diffuser. The rear spats do little as far as aerodynamic performance. We see negligible gains in downforce and drag when running CFD performance on the units.
