I used M6 rivnuts .. lots of them.

 

nice, thanks.

Anyone who like to share picture of front down force arrangement on the VX220?

[Rickybobby]

Keen to see what’s available off the shelf in terms of dive planes, splitters and front arch vents.
Typically on actual race cars dive planes are used to trim the aero and often added to compensate for a rear deck gurney.
Given that they could be quite effective on a VX with a coupe back and and say a 80mm gurney on the back.
They also only tend to be used on cars with c.500bhp because it’s not the most efficient way of producing downforce and even then only in qualifying. They tend not to be used on high speed circuits rather tracks such as Estoril.
The scrolling vortex mentioned earlier is generated by the inverted half cone feature and end fences on the splitter, this vortex is then used to keep flow attached to the rear of the car, seal the under floor and control air through side pods or extract from the back of the arches.
What solutions are out there for extracting air from the rear arches? Is it enough to vent the inner arch into the engine bay or does it need something more purposeful?
For me aero will consist of a splitter and long, low angle diffuser and ditch the mirrors. A coupe back in the German/eltech style with an actually tested efficient wing such as a 183 from DJ race cars and a small rear deck gurney to help drive the floor. I’ll throw some damper pots on it and see where that ends up and add dive planes if needed. Again though I’ll be around the 300bhp mark so won’t be going to extremes on size.
That’s my 2p worth🤣

I've driven a few different vx's in track and none have suffered with lift at high speed but all feel slightly different.

I've sat at 130 on an autobahn and it honestly felt fine with no aero mods at all (apart from the wind noise) but the car is raked slightly.

I'm sure some of the aero measures will add downforce but I'd make sure your geo is as you like it through a provider who can translate the way you like the car to drive in to a setup, otherwise it'll feel like trying to exercise your way out of a bad diet...

[Aerodynamic]

Is this for reinforcement or helping to make any downforce

 

 

It´s not to unlike my splitter.

Mine is to the right, the left is painted.

 

Side skirts.

Are those  to produce downforce? Air traveling along a angled plain

should create some downforce.

or Are they to seal and prevent air to come under the car?

 

Or can you do both? Making a L shaped side skirt?

It's for drag reduction...

I have no picture of the inside, but I glued two vertical alloy profiles to the clam and I cut the threads for the canards into it.

I fixed the alloy profiles in vertical because the clam is less curved in this direction and the profiles have the greatest surface to the clam like that. 

So one vertical alloy profile "connects" the front screws of the canards, and one the back screws. That also stabilizes the clam itsefls and it can take more force.

Its stable enough for 270km/h.

Where did you get them please?

And wher did you get your front bonnet ??

[FabianG]

The Canards were a special production for my car. 

But meanwhile you can buy them from Tuneconcept.

The bonnet was also a special production from a guy from germany and only 10 of them were made. 

I dont think he produces them any more, but if so I'll tell you. 

 

[Aerodynamic]

Do you have a better Picture of the bonnet?

At the moment I dont have any better pictures. 

But there is one bonnet for sale in the Facebook group:

How much weight did you save with it ?

[FabianG]

I dont know, but its very thin and light compared to the OEM. 

[Aerodynamic]

Hi there, I have seen that the exige V6 have fold line on there rear wing endplates. Does anyone know 

if this increase the downforce or if it´s just for the looks?

 

 

Br, Per

[Aerodynamic]

No one?

Wrong thread?

 

I thought with the possibility of 3D Printing I could design the endplates a littlebit like a diffuser, make it wider in the front and rear of the endplate.

Honestly i think it's for look only...
Reverie selks them and if there was a benefit i think they would let us know...
But they say nothing about them...

[2-20]

You'd better check what "doctor ed" has posted about his end plates...

[Nev]

Lifting that wing up into clean air would make vastly more downforce than just putting end plates on it.

 

Even my wing which is 1" above the roofline still isn't high enough.
