How much tire clearance does the 70mm extension actually give me?

The +70mm dimension is the flare extension from the OEM body line. This directly translates to additional tire and wheel clearance — verify your wheel offset and tire width against your current suspension setup to confirm fitment for your specific build.

What wheel sizes and offsets will work with these flares?

The 70mm extension accommodates wider wheel-and-tire combos than stock. Cross-reference your wheel diameter, width, and offset against your suspension geometry — the flares provide the clearance envelope, but your suspension travel and geometry determine the final limit.

Do I need to drill into the body to install these?

Reference your vehicle's OEM body line and existing mounting points before installation. Preparation and mounting method depend on your specific fender structure — sand and prep all surfaces before assembly to ensure proper fit and finish adhesion.
