Evo X undertray / underbody cover
 

Hi guys,

Who of you track drivers are working with a underbody cover to improve the aerodynamics? Here in Germany there no leagal way to put a big carbon wing on the trunk. Therefore I'm thinking about to improve the underbody.
Any thoughts or ideas how or where i can get the parts?

Try [email protected] indigo. He was selling under trays for evo ex's a while back. I can't remember which ones though.
Voltex do one too.

[email protected] is selling SSP's he has one off his old X as well for sale.

That's the SSP undertray in your first post!
I've got one, it's brilliant :)

The ssp is good for the front of the underbody. But what is about the middle an rear of it?

Can you feel a difference between stock an ssp?

Middle will be something custom don't think there is a flat bottom of the shelf. Rear only one I have seen so far is Varis but there maybe others..

For the front there is ssp or this here available.
For the rear there is also a nice diffusor available. Only the middle section is not available.

Also, I would like to understand what bring a better downforce effect. A long splitter and flat underbody, or the jun frond diffusor?

No Arno.............. Far too subtle for me!

Nobody an idea how to improve downforce and aerodynamics?

You need a flat floor front to rear, as soon as this is broken any tray at the rear or diffuser will be useless which is particularly tricky around diffs and axles. This is what I've learnt when I was designing the underfloor aero for the jaguar XF

I will have a voltex front under tray available soon..

true, you only have to look at the way modern day race cars are nowadays and go from there...

but dont go for a fully flat underbody otherwise you could make your car very dangerous.... :eek:

available to offer me?
