How much tire clearance do these flares actually give me?

The 70mm extension per side opens up room for wider rubber or more aggressive wheel offsets. Before installation, measure your current tire-to-fender gap and compare it to your wheel and tire specs to confirm your desired fitment will clear the inner fender lip.

What wheel sizes and offsets will work with these flares?

Offset compatibility depends on your specific wheel diameter and width. The added flare width gives you more latitude, but you'll want to verify clearance between your chosen wheel/tire combo and the flare outer edge. Check your wheel specs against your fender opening before ordering.

Do I need to drill the car to install these?

These are designed to mount using existing body panel attachment points. Verify that your vehicle's OEM fender mounting locations align with the flare mounting provisions before finalizing fitment — some vehicles may require minor drilling depending on panel alignment.
