Will these winglets interfere with my bumper trim or splash guard?

Interference depends on your bumper profile and how far the winglets extend. Test-fit them against your bumper before committing to fasteners. Most setups clear without issue, but measure your bumper lip thickness and splash guard location to confirm clearance on your specific vehicle.

What mounting holes does this use?

These are universal splitters, so they rely on your bumper's existing fastener pattern. Identify the bolt holes on your bumper first, then drill corresponding holes in the winglets or use self-tapping fasteners. Reference your bumper's hole spacing to determine the best anchor points.

How stable are these at highway speed?

FRP winglets are rigid and stable when properly mounted with fasteners torqued securely. Ensure all mounting points are tight and that the pieces sit flush against the bumper. Any flex or movement indicates loose hardware — retorque all fasteners before extended highway driving.
