Hi everyone. I was curious on like the Japanese body kits (Rocket Bunny, Liberty Walk, RWB, & so on....). My question is does anybody knowThank that they have been aerodynamically tested? Thank you.

Tested to do what? Produce downforce? Reduce drag?

Your question is too vague to warrant a good answer.
 
As small as RWB is, I doubt there's a lot of aero testing done by Nakai-san being a small company, but the design seems heavily influenced by the old 993 GT2 race cars & a lot of the owners track them.

I don't know about Rocket Bunny, but I can't believe for a second Liberty Walk's kits are made to be aerodynamic when they finish the cars like this. Seems very counter-productive.

They all surely take a lot of cues from the motorsport world but beyond that I don't think they give aerodynamics that much thought. Kei Miura does 3D model his kits but I don't think that entails much in terms of aerodynamic testing. And coming to think of it, the double-triple-whopper-yooper spoiler on Nakai's personal 911 "Rotana" is absolutely hideous and should be as aerodynamic as some window cleaning scaffolding.

Dumb as 🤬, as almost anything on stancenation. But what do we know? We're just "haters"...

While that particular setup may or may not be functional, double-spoilers can be if done right.

Looks incredibly stupid, but Nakai may have some reasoning behind it. Or then again, maybe he was bored.

:lol:

They almost look like they would produce rear end lift...

It kinda looks like (and this assumes they actually produce downforce, which is a big assumption) they would create a moment about the rear axle and reduce weight on the front wheels.

(Not that that's what's happening in the gif)
 
Some of the RWB cars are actually track used, which in my opinion really sets them apart. They may not be the fastest cars on track, but they sure look good doing it. My personal car has a lot of influence from RWB and "works" racers from the 80s and 90s. Big fenders, wide wheels, aero and I track it as well. While some of the RWB cars are stanced and for show only, a good portion of the cars in Japan are tracked as well.

Air passes over and under them, they are wings, not spoilers.

That's not the only definition though, is it? For example air passes under the spoiler on my car and I wouldn't call it a wing. I know this is slightly off topic and I apologise for that.

I would think if it's purpose is to create downforce then it's a wing, and if it's purpose is to spoil the air flow to reduce a pressure zone from being generated it is a spoiler, no matter what the appearance.

And if it's just there for no function except to look good, well it's a decoration / air brake lol.
 
A spoiler can have separation from the car body and itself. But if it's a free-standing wing meant to create downforce in clear air instead of adjusting the boundary layer, it's an... erh... wing.

Definitions be vague.
