Downforce/Drag/Aero
Okay, well this guy made a decision that he possibly regrets. I recently purchased a Voltex Wing for a really really good deal. Installed fine and everything went smooth.
However I didn't account for the drag of the wing to be that strong. I daily commute 120km total to work and back. I realized that my gas milage took a small hit and I have to be harder on the accelerator with inclines - even if its slight just to maintain speed. Since I love the wing a lot, I'm trying to think of ways to combat the drag. I'm new to modifying cars and to be honest - this is my first car under my name. I was thinking of adding a splitter and rear diffuser, possibly getting the bottom as flat as possible, while still being able to service the car easily. Maybe the car just needs more power so I don't have to be so aggressive on the pedal - as we know the torque on these cars is lacking. Any suggestions or help is greatly appreciated, thanks!

Try to minimize the angle of attack?

You're problem here is literally the functionality of the wing. Get a smaller wing or replace it with a spoiler

You can't fight physics. A wing is always going to add drag. You can minimize it to some degree if it is adjustable. A rear-diffuser will reduce drag somewhat, but I doubt it will fully offset the wing. Same for the splitter, but I believe it has even less effect than the diffuser. Remember, the real goal of most aero mods, and 100% true of wings, is increased downforce in corners. |

The only real answer in your case is to get rid of the wing.

Like @mav1178 suggests, get rid of it, OR ....... just remove it and put it back on for track days ...... or show and tell meets.

Never mod your car unless you know exactly what limitation you're solving.
And at what cost they come. Wings add drag. That is their point. Do you really need downforce at high speeds? Do you even know at what speed your wing even helps your high speed cornering? Sell the wing. |

If you love the wing:
Reduce its angle of attack. Getting a splitter and a diffuser won't offset the drag from the wing. They sure won't offset the increased cost from running 120km daily with it either. |

I was looking at some pictures of the Voltex Wing - Type 1S for the BRZ, and it looks like you can adjust the angle of attack by changing the front screws. Other model Vortex wings based on what I can see from Google results are also adjustable too, so it looks like if you want to keep your wing you can reduce the angle of attack (i.e. make the wing flatter rather than more angled). You will still have some drag, but at least you can minimize it as best you can.
