Seeking Feedback on Alpha-N Wing for G87 Track Use
Hi everyone, I've been researching wings and am particularly interested in the Alpha-N wing for the G87. However, I haven't been able to find any statistics on the downforce and drag it provides. Multiple websites mention that it's functional, but I'm looking for specific figures.
I've been taking my G87 to the track and plan to do so more frequently starting next year. There are other companies offering wings with good downforce numbers at lower prices than Alpha-N. Does anyone know how effective this wing is? |

I'm following out of curiosity in case you find something. When looking for a wing I could only find data on Verus and Adro.

Probably not effective at all because it's RICE. Plenty of real wings you can buy if you're actually chasing downforce and track performance. You can go see the JackiePhD build on YouTube.

I suppose the OEM wing from the E30 M3 and the E36 M3 LTW are non-functional and “rice” too, huh?

If we're talking about aggressive track use, yes.

That's not true at all... spoilers with aluminum (or carbon) mounts are just cheaper to make and more universal to fit different cars.
The fully molded spoilers are definitely functional (ever seen an F1 car 2022+?, or rally cars etc), whether or not the BMW MP or AlphaN ones are designed to be as aggressive as a race type spoiler, for a street car is really the question. Which I would say no, but they would definitely add downforce to the rear, just depends on how much you are looking for. But I can guarantee the e30 M3 and e36 LTW cars were VERY functional!

oh man- when I read Alpha-N for some reason I thought of the Akrapovic wing.
How does the Apha-N attach? Please tell me it's not double-sided tape?! The Alpha N is in between the Verus and Adro in price. I would go with Verus if I were you.

Yes the car is for the road, but if someone builds it for the track, then it become a track car no? I would say Jackie Dings car is a track car He also didn't run an AlphaN spoiler, and neither would I... I was more referring to the e30 and e36 LTW comment, and those were race cars first

Thank you for all the comments above. I like the Ardo and Verus wings, but unfortunately, they are not for German market due to TUV regulations etc.
I absolutely love the look of the Alpha-N wing and am trying to decide if it makes sense to spend double the amount on a part that offers lower performance. |

I wouldn't expect too much from a wing the size of an Alpha-N one in terms of downforce. Most are around 0.15m^2 area. Assuming the coefficient of lift is about 1.0 for a properly wind tunnel tested one that is below it's maximum angle of attack to avoid stall, it will generate 231N (52 lb) of downforce at 50m/s (180km/h, 112mph).
As the wing is quite far back, it will create a larger moment on the rear axle than fuel in the fuel tank, but will be about equivalent to the handling and grip change on the rear tyres to running a full tank of fuel vs 1/4 of a tank, at 50m/s. |

Not made up, just basic aeronautical equations (my user name has something to do with that, background wise)
Lift is 0.5 x ρ x A x CoL x v^2 = 0.5 x 1.23 x 0.15 x 1.0 x 2,500 = 230.6. ρ is no more than 1.23kg/m^3 in summer conditions, in fact today at my altitude (1250m) and temperature (30C), the air density is only 1.013kg/m^3, so I would only get 190N of downforce from the same wing. |

Hello
without our Gurneys we have approx. 88kg downforce at 200 km/h. But that depends on a few other factors and can change depending on the car. Our wing is not just for looks. We have developed / simulated the entire vehicle in CFD. |
