How much tire clearance do these flares provide?

RBS-style flares are designed to work with moderately aggressive setups. Measure your current wheel and tire package, then compare against your desired upgrade — the flares follow the natural arch of the fender line and won't restrict typical performance tire sizes in standard offsets.

Do I need to drill or modify the body to install these?

Installation method depends on your chosen mounting system — fasteners, clips, or adhesive — which you'll select based on your preference and local shop practices. Verify mounting hole locations on your vehicle's existing fender seams before committing to hardware placement.

What wheel offsets work with these flares?

The flares accommodate standard and moderately aggressive offsets common to the period. Reference your vehicle's original fender dimensions and compare them to your wheel and tire specifications to confirm fitment for your specific setup.
