How much tire clearance does the 40mm width give me?

The 40mm extension provides enough room to clear moderately wider performance tires and wheels without rubbing the original fender. Verify fitment with your specific tire and wheel combination by checking the overall width and load rating against your vehicle's suspension geometry.

Do these flares require drilling or modification to the original fenders?

Installation uses the existing mounting points on your vehicle's body. Check your owner's manual or service documentation for fastener locations and torque specs before assembly.

What wheel offsets work with these flares?

The 40mm extension accommodates a range of offsets typical for performance builds. Compare your wheel's backspacing and offset against the additional fender clearance to confirm fitment — negative offset wheels generally offer more inward clearance.
