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

The 70mm width gain lets you fit wider wheel and tire packages than OEM fenders allow. Your actual clearance depends on tire sidewall height and suspension setup — measure your current fender opening and add 70mm to see what size tire your wheel will clear without rubbing.

Do these flares require drilling into the body or factory panels?

No drilling required. These bolt to the existing rear quarter panel mounting points using factory hole locations. Verify your vehicle's OEM attachment points before installation to confirm alignment with the flare mounting tabs.

What wheel offsets work with these flares?

The 70mm extension accommodates wider wheel packages across a range of offsets. Reference your wheel specs and current tire size, then confirm fitment by test-fitting with your actual wheel and tire combination — this accounts for suspension geometry and body roll that static measurements won't catch.
