How much tire clearance do these flares add?

Circuit flares extend outward to accommodate wider stance setups. Measure your current fender-to-tire gap, then compare the flare profile against your planned wheel and tire combo. Account for suspension travel and any lowering; verify clearance at full compression before final install.

Do I need to drill the fenders to install these?

No. These flares bolt to factory mounting points already present on the fender. Standard fasteners will secure the corners; sand and prep the bolt holes and surface before assembly to ensure solid panel fit.

What wheel offset and size work with these flares?

Circuit flares are designed to work with a range of wheel offsets and diameters. Your specific setup depends on suspension height, tire sidewall, and offset. Lay a straightedge across the tire to the flare edge to confirm clearance on your car before committing to offset.
