How much tire and wheel clearance do these add?

The Gran Veloce profile extends the fender line outward to accommodate wider wheel setups without rubbing. Measure your current tire sidewall to rim gap, then compare against your target wheel width and offset—the flare profile will give you additional clearance beyond the factory fender edge. Verify fitment with your specific wheel size and offset before committing to a build.

Do I need to drill or modify the existing fender?

These flares are engineered for factory mounting points. No drilling or cutting of the original fender is required. Installation uses the OEM fastener locations, so verify that your vehicle's bracket system matches the standard configuration before ordering.

What finish prep should I do before installation?

Carbon fiber ships uncoated. Sand and prep the surface lightly, then apply a clear coat or protective UV finish to lock in the twill weave and prevent oxidation from road salt and UV exposure. Install after the finish has fully cured per your product's cure time.
