How much extra tire clearance do these flares add?

GT500 flares are designed with modest bodywork extension that accommodates slightly wider or lower tire setups. Measure the gap between your current tire and fender, then verify clearance with your chosen tire and wheel combo before final fitment.

Do I need to drill or modify the existing fender to install these?

These flares are engineered to work with factory mounting locations on the fender and body line. Refer to a detailed installation guide or your vehicle's service manual to confirm mounting hole alignment before drilling.

Can I use these flares without a complete wide-body kit?

These are designed as part of a complete wide-body system. The GT500 profile and body lines are engineered to work in combination with the kit's other panels. Standalone installation may result in fitment gaps or misaligned body lines.
