How much tire clearance does a 50mm flare actually give me?

The 50mm extension provides clearance for modern-profile tire sizes without major suspension drops. Measure your current tire diameter and sidewall width, then verify the installed flare clears your wheel and tire combo by at least a quarter-inch at full lock and full compression.

Do I need to drill into the fender or use existing holes?

Reference your vehicle's OEM fender mounting locations before installation. Most setups use existing holes, but confirm fitment with the flare test-fit first — factory hole patterns can vary slightly by year and production batch.

What wheel offsets work best with these flares?

Circuit flares pair well with zero to moderately aggressive offsets. Verify clearance between the wheel lip and the flare edge at full steering lock and suspension compression — this is the controlling measurement for your specific wheel and tire setup.
