Do these fenders use factory mounting points or require new holes?

They're engineered to use existing factory anchor locations. Before installation, verify your vehicle's bolt hole alignment and consider a dry fit to confirm fitment with any existing body modifications or wide-body kits you may have installed.

What prep work is needed before painting?

Sand and prep the surface with standard finishing techniques before applying your chosen primer and paint. FRP is primer-receptive and accepts most automotive finishes—confirm compatibility with your paint supplier if using specialty coatings.

Will these fenders affect tire clearance or suspension geometry?

The 40MM extension adds width at the fender line. Verify clearance with your current wheel and tire setup and any lowering springs or coilovers you're running. A test fit is recommended before final installation.
