So, I’m genuinely curious: what exactly does it do? I have these $90 fins from Velossa, but they are obviously for the looks, and I do like the way they look.
This is a much more substantial piece from Verus (and pricier, too) - so, there are expectations of some aero benefits.
Are there any numbers that would quantify the alleged downforce? Here’s a quote from one of the sites about aftermarket diffusers:
“Are aftermarket diffusers functional?
Rarely. Most aftermarket air diffusers are for show only. These rear diffusers do not efficiently increase airflow out the back of the vehicle from under the vehicle. They simply just add dead weight to the car and in some cases even increase turbulent air under the car thus reducing efficiency by increasing drag. Unless properly developed in a wind tunnel and the manufacturer posts graphs and numerical data showing efficiency increases through testing, the diffuser is just for show.”
So... ?
