Pre-assembledAerospacers are bolted down perpendicularly to create a brace that reinforces the rear valance and evenly spreads the load from impacts across the surface. It also allows the diffuser to follow the body kit contour to keep it flat and level.
Valance is installed to the car through bolts and nuts while the Flow-Lock diffuser fins simply click into the valance (once locked into the valance it is secure). It is also possible to install when your car is on the ground.
