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

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.
