FH6 Car Customization Guide: Window Decals, New Aero & Engine Swaps

By FH6 Guide Team|8 min read

Customization Finally Done Right

Playground Games has detailed FH6's car customization system, and it's what fans have been asking for since the Xbox 360 era. Window decals, vehicle-specific aero, motorcycle engine swaps — the wishlist items are finally here.

Redesigned Forza Aero

In previous games, the same generic front splitter looked equally awkward on every car. FH6 fixes this.

  • Aero parts are individually shaped to match each vehicle's existing body lines
  • No more one-size-fits-all splitters and wings
  • New gooseneck rear wing design replaces the old style
  • Separately paintable end plates on rear wings

    • ---

    Window Decals: First Time Since 2007

    For the first time in 19 years, players can apply decals to window surfaces.

  • Fully adjustable opacity — from subtle sun visor strips to fully opaque designs covering the entire glass
  • Works with the existing livery editor
  • Long overdue, but finally here

    • ---

    Wheels: 100+ New Models + Staggered Fitment

    Over 100 new wheel models join the roster. Crucially, **different wheels can now be fitted to front and rear axles independently** — a massive deal for stance and drag builds.

    Tire treads now show **cosmetic wear in real time**.

    Motorcycle Engine Swaps

    Since FH6 is set in Japan — the homeland of kei cars — players can now swap **motorcycle engines into kei vehicles**. Which specific combinations are possible remains undisclosed, and it's unclear whether bike engines work in regular cars like the Mini Cooper.

    Important Caveat: Livery Transfers

    Due to geometry changes, **only vinyl sets can be imported from old liveries at launch**. Full livery transfers from FH5 are not supported. For players who invested hours building complex designs, this is a genuine disappointment — plan to recreate your masterpieces.
