How much tire clearance do these flares add?

The C Spec flare profile is designed to accommodate wider tire-and-wheel combinations. Measure your current setup and compare to your target wheels and tire width—C Spec geometry clears most popular motorsport offset and diameter combinations, but verify fitment against your specific build.

Do these require drilling or modifications to the original fender?

Installation method and fastener points depend on your mounting strategy. Reference your vehicle's OEM fender structure and existing body lines before assembly—bolt-on attachment to factory holes is common, but your specific car may require additional evaluation.

What prep and finish work is needed before installation?

Sand the surface with appropriate grit to promote adhesion, then apply your chosen basecoat and clear. FRP responds well to standard automotive paint processes—verify compatibility with your refinish system before spraying the entire set.
