FAQ — Rear Diffusers

How do I confirm diffuser fitment?

Match your model year, chassis code, and bumper style. Exhaust cut-outs and parking-sensor holes differ by kit — send details to sales@cargym.com if unsure.

Are these carbon fibre?

Many listings are carbon or carbon-look composites; others are FRP or ABS. Read the product description for material and finish (gloss, matte, exposed weave).

Do you ship diffusers worldwide?

Yes. CarGym ships worldwide with multi-currency checkout. Large aero pieces may require special packaging — we confirm shipping before dispatch.

Will a diffuser clear my exhaust tips?

Clearance depends on tip diameter and tip-out position. Share photos of your rear bumper and tips with sales@cargym.com for a fit check.

Can I buy a diffuser with a matching spoiler or lip?

Often yes — many brands sell matching aero. Browse this hub plus our Spoilers collection, or ask us to bundle recommendations.

How do I order or ask a question?

Email sales@cargym.com with your chassis and preferred finish.
