Installation of Aerodynamics

All aerodynamics are manufactured with fiberglass unless otherwise noted. Due to the material used in production, the body kits will NOT be a direct bolt-on. These body kits may require prepping, sanding, shaving, filling gaps, cutting, or other extensive body work. These modifications may include removal or cutting of the reinforcement bars. By complying with our policies, customer understands the procedure and possible difficulty in installing the body kit.

We HIGHLY recommend that a professional body shop with custom fiberglass body kit experience perform the installation. Refunds will not be issued due to poor fitment of the body kit. If fitment is off by extreme margins, a refund will be considered.

Notice of Fitment

As with any other aftermarket body parts, fitment is not perfect. Do not expect OEM fitment. DTMFiberWerkz FRP aerodynamics combine fiberglass and flex resins to obtain its unique flexible and durable features. If the part you receive has minor flex and bends, do not be alarmed.
