Product Overview

The 2021–2022 BMW 4 Series G26 4-Door Dry Carbon Fiber Wheel Arch Kit (10-Piece Set) provides a coordinated exterior upgrade for the Gran Coupe. Its multi-piece design follows the front and rear wheel arch contours, creating a wider and more defined side profile without replacing the original fenders.

Manufactured from prepreg CFRP and autoclave-cured for low weight, high rigidity, and stable geometry, the kit is available in matte dry carbon or optional gloss finish. Each component installs with automotive-grade adhesive, requiring no cutting or visible drilling.

This BMW G26 dry carbon wheel arch kit is suitable for tuning brands, automotive distributors, professional installers, and private-label exterior accessory programs.

B2B Problems We Solve

1. Missing or Incorrect Kit Components
   Multi-piece wheel arch sets can be difficult to identify and pack correctly.
   Our Solution:Each component is labeled by vehicle side and installation position, with a version-specific packing list.
2. G22, G23, and G26 Fitment Confusion
   Coupe, Convertible, and Gran Coupe body panels are not interchangeable.
   Our Solution:Chassis code, body style, model year, and vehicle photos are verified before supply.
3. M Sport and Standard Body Differences
   Bumper, rocker, and wheel arch transitions may vary between exterior packages.
   Our Solution:Body package and adjoining panel shapes are checked against the selected kit version.
4. Poor Alignment Across Multiple Sections
   Small dimensional errors can create inconsistent gaps between connected pieces.
   Our Solution:Coordinated tooling and kit-level fitment inspection support cleaner transitions.
5. Inconsistent Weave Across Ten Pieces
   Different weave directions or gloss levels can make the installed kit look mismatched.
   Our Solution:Components are manufactured and inspected as one complete visual set.
6. Weak Adhesion on Long or Curved Trims
   Incorrect tape selection or surface preparation can cause lifting.
   Our Solution:Automotive-grade adhesive, preparation guidance, and adhesion promoter recommendations support secure fitting.
7. Unstable Repeat-Order Quality
   Variation in dimensions or kit contents can increase workshop labor and returns.
   Our Solution:Standardized tooling, documented production procedures, and pre-shipment kit inspection support repeatable supply.
8. Shipping Damage and Component Loss
   Narrow trims and multiple small sections can be scratched, bent, or misplaced.
   Our Solution:Individually separated packaging and clear parts identification improve export protection and order accuracy.
