How much additional tire clearance do these flares provide?

The RBS V2 profile extends outward to accommodate wider tires and wheels without rubbing. Measure your current tire width and sidewall height, then compare against your desired setup; the flares provide the clearance envelope for modest upsizing without suspension modifications.

Do these require drilling into the fender or mounting to existing holes?

Verify your vehicle's OEM fender hole locations and mounting points before assembly. Standard FRP flare installation uses factory attachment points; confirm compatibility with your specific configuration to avoid unnecessary drilling.

What wheel offsets and sizes work with these flares?

The RBS V2 flare profile accommodates a range of wheel sizes and offsets. Cross-reference your wheel specifications (diameter, width, offset) against your tire choice and suspension setup to ensure clearance — this depends on your total package, not the flares alone.
