The diffuser is one of the STO's most recognisable rear details. This Auto Addict replacement keeps the original fin and contour arrangement, adding a consistent exposed-carbon finish across the lower rear bodywork.
SKU: AA_STO_OE_SDLBS_002
The diffuser is designed to work with the factory STO rear bumper, exhaust area and underbody aero layout. It preserves the factory airflow characteristics and fits the original STO mounting arrangement.
The exposed weave continues onto both sides of the part, so the finish is there to enjoy from more than one angle. It is made entirely from pre-preg dry carbon fibre, with no fibreglass backing. Autoclave curing, CNC-machined moulds and 3D-scanned geometry provide a lightweight, rigid structure and carefully reproduced shape.
A UV-resistant high-gloss clear coat gives the carbon its depth and helps protect the finish from sunlight. This is an Auto Addict replacement for the factory STO part, designed around its original mounting locations.
If you are replacing both sections, the matching factory-STO rear bumper shell is available separately. Keep your existing shell if it is the diffuser alone you want to change.
We can also help with custom tuning for your Huracan STO. Tell us about your car and the upgrades you are planning and we can discuss the right approach. Tuning is available as a separate service.
