How much tire clearance do these flares provide?

These flares are engineered to accommodate wider wheel and tire packages without rubbing. For your specific setup, measure your current tire diameter and compare against your desired upgrade; the flares are designed with internal clearance for modest upsizing. Verify fitment with your exact wheel offset and tire sidewall height before installation.

Do I need to drill the fenders to install these?

No drilling required. The flares bolt directly to factory fender mounting points on the R35 platform. Use existing OEM fastener holes for a clean, reversible install with no modification to the underlying panel.

Can I use these flares without the matching front bumper?

The fender flares stand alone as a styling upgrade, but they are part of the complete LBW kit. For visual cohesion, the matching front bumper (sold separately) is designed as a complementary panel. You can install the flares independently, though the full kit was engineered together.
