Expert FRP Manufacturer

FRP Rear Quarter Panel

Developed for rear body sides spanning the door opening, wheel arch, and tail section, this composite part reproduces the wheel-arch profile and shoulder line from buyer-controlled vehicle data. We form and trim the panel around the roof or pillar edge and rocker, stable edge returns, functional openings, and the requested level of surface preparation.

How we make it

Rear Quarter Panel Surface-to-Part Manufacturing Process

The Rear Quarter Panel moves from vehicle-surface and package review through mold construction, composite layup, trimming around the roof or pillar edge, fit-reference inspection, surface preparation, and protective packing.

01

Rear Quarter Panel Vehicle Data and Fit Review

Review the wheel-arch profile, shoulder line, door gap, lamp return, and rear-corner surface, neighboring body data, and installation requirements for the roof or pillar edge, rocker, bumper, lamp, inner structure, fuel door, and mounting flanges. The buyer package must define trim lines, gaps, openings, seals, mounting references, clearances, and the surface-preparation target.

  • Review the wheel-arch profile and shoulder line in the vehicle package
  • Mark trim lines, gaps, openings, and the roof or pillar edge
02

Rear Quarter Panel Mold and Composite Forming

Build the mold around the released wheel-arch profile, then form the panel with specified laminate, reinforcement, returns, inserts, and openings required for the roof or pillar edge, rocker, and safe downstream handling.

  • Capture the released wheel-arch profile
  • Build stable edges, returns, and mounting areas
03

Rear Quarter Panel Fit References and Packing

Inspect trim edges, specified gaps, mounting locations, the roof or pillar edge, and the prepared visible surface. Protect the panel's edges and finish for buyer-led fitment, final painting where required, and vehicle-level validation.

  • Check trim, openings, mounts, and visible surfaces
  • Verify references around the roof or pillar edge and rocker

Vehicle Programs for the Rear Quarter Panel

This part is intended for rear body sides spanning the door opening, wheel arch, and tail section. It is supplied as a buyer-specified composite body component for vehicle development, conversion, restoration, replacement, or low-volume production, with final vehicle integration controlled by the buyer.

  • Applicable to rear body sides spanning the door opening, wheel arch, and tail section.
  • The molded surface and local forms may include the wheel-arch profile, shoulder line, door gap, lamp return, and rear-corner surface.
  • Edges, openings, and attachments must relate correctly to the roof or pillar edge, rocker, bumper, lamp, inner structure, fuel door, and mounting flanges.
  • Projects may use released CAD surfaces, scan data, a reference vehicle, or a sample part, with buyer-led fit reviews before repeat production.

Custom options

Rear Quarter Panel Surface, Edge, and Mounting Options

Buyer CAD, scan data, or a reference assembly sets the visible surface and surrounding package. The installation design then defines edge returns, trim lines, gaps, openings, reinforcement, brackets, removable features, and the required paint-preparation stage.

  • Reproduce the wheel-arch profile, shoulder line, door gap, lamp return, and rear-corner surface from the buyer's released class-A, scan, or reference surface.
  • Set clearances, trim edges, and attachment provisions around the roof or pillar edge, rocker, bumper, lamp, inner structure, fuel door, and mounting flanges.
  • Form or machine vents, lamp or glazing apertures, service cutouts, drain points, fastener holes, and removable areas shown in the installation package.
  • Specify the color reference, texture, gloss, edge finish, primer or paint-preparation level, inspection method, and protected packing.

Need to know

Common buyer questions

Can the Rear Quarter Panel be matched to our CAD, scan, or reference vehicle?

Yes. We can develop the part from released CAD surfaces, scan data, a reference assembly, or a sample panel showing the wheel-arch profile and shoulder line. The buyer must provide controlled fit references for the roof or pillar edge and rocker and neighboring bodywork.

Can mounting features and functional openings be included in the Rear Quarter Panel?

Yes. We can form or trim buyer-defined returns, brackets, inserts, fastener holes, and functional openings associated with the roof or pillar edge, rocker, bumper, lamp, inner structure, fuel door, and mounting flanges. Their locations, clearances, attachment loads, and installation method must come from the vehicle developer.

Does the Rear Quarter Panel include vehicle-level compliance or crash validation?

No. GFIND supplies the composite part to buyer drawings and inspection references. Final fitment, attachment design, structural suitability, road compliance, crash assessment where applicable, and complete-vehicle validation remain with the buyer or vehicle OEM.
