Frequently asked questions
Do rear diffusers actually improve aerodynamics or are they purely cosmetic?

A well-designed, vehicle-specific rear diffuser can produce measurable aerodynamic benefits by managing airflow under the car and reducing rear lift at higher speeds. Diffusers that have been CFD-tested (such as the ADRO X3M LCI diffuser in our range) produce quantified improvements in rear stability. Purely cosmetic diffusers with no proper underbody channel geometry deliver less aerodynamic benefit but still provide significant visual enhancement.
What material options are available for rear diffusers?

We offer rear diffusers in pre-preg carbon fibre (the highest specification - used on ADRO products), standard CFRP 2x2 weave carbon and high-quality ABS plastic in gloss black. Pre-preg is the lightest and most visually refined option; ABS gloss black provides an accessible, durable alternative at a lower price point.
Will a rear diffuser fit around my aftermarket exhaust?

This depends on the specific diffuser and exhaust tip size/position. Most vehicle-specific diffusers are designed around the OEM exhaust exit point. If you have an aftermarket exhaust with a different tip size, please contact us to confirm clearance before ordering.
How are rear diffusers installed?

Most diffusers in our range bolt directly onto existing mounting points on the rear bumper. No drilling, cutting or permanent modification is required. Installation typically takes 20–45 minutes with basic tools.
