If they are 100% cosmetic I guess this discussion is futile but on the off chance they're not as lots of race cars use them I have the choice between a wing that I can make new mounts for or buy a duckbill style .
Would I be correct assuming that a wing would use more fuel over the duckbill as I do a lot of country driving or is that wrong  |
Most of the duckbill spoilers on this platform are purely cosmetic. They may have function though likeness but, don't expect much. Also (as stated previously) avoid the roof spoilers there was a video and simulated cfd data on them for this car posted and while back.
Your not going to notice the difference in fuel consumption before and after. You may enjoy keeping the car at higher speeds with the inproved stability/feel with a spoiler though effecting milage. Personally I think most of us have found the front wheels are a bigger problem at higherspeeds stock than the rear. 110+mph and the front gets floaty.
Also there isn't a 'best' answer. When the time attack guys are setting up their aero dynamics, they are dialing it in as a complete car taking in consideration to their other aerodynamic modifications, ride height and weight. It's many small factors that result in a big change.
