How much tire clearance does the 40mm width gain?

The 40mm extension provides clearance for moderately wider tires or slight suspension lift. Verify your wheel and tire fitment against the flare profile before final installation — wider tires may still require trimming depending on your suspension geometry and offset.

Will I need to drill into the body to install these?

Installation typically uses existing body mounting points, but your vehicle's factory holes and fastener locations should be verified before assembly. Reference your OEM body panel documentation to confirm hole spacing and fastener sizes.

What finish should I apply to the surface?

Sand and prep the surface according to your chosen paint system before application. FRP accepts automotive urethane, acrylic, and single-stage paints equally well — follow your paint manufacturer's surface prep recommendations for best adhesion and durability.
