Do these fenders come with mounting hardware?

The set includes the two fender panels. Fasteners and brackets are not included — source hardware based on your conversion mounting strategy and existing body attachment points.

What prep work is required before painting?

Sand the surface to scuff the finish, then clean off all dust. Apply your chosen paint system directly. No additional primer coat is required if your topcoat bonds to the prepared FRP base.

Will these fit my S15 conversion if I'm using a different subframe or body kit?

These panels are designed around S15 mounting points. Before ordering, verify that your conversion uses factory S15 fender attachment locations. If your build uses custom bodywork or non-standard integration, measure your fender opening and compare to the OEM S15 dimensions.
