I was looking at the Varis vortex generators (not the little shark fins), and the rear diffuser.

First question is about the diffuser. It comes in 2 widths 705mm, but some websites say the other one is 605mm and some say its 650mm. Which is it?

Then, the vortex generators. Has anybody installed these? Have they noticed any difference? Are they supposed to increase downforce, and if so how?

I was wondering how people would think this would look like on an amuse rear add-on. I'm looking for functionality, but i don't want to create a complete abortion at the back of the car. I'm looking for a little extra downforce, especially in the rear, for the track.

Thanks

 

Im sure under track condition/speed they help with drag.

In the real world you wont notice or feel it a tiny bit.

 

bump!

 

Sorry I didn't see this thread sooner.......

For the universal rear diffuser....the dimensions are:

Width - 605mm (Medium) 705mm (Large)
Length - 750 mm
Height - 140 mm

 

Ok thanks. I don't suppose you know about the vortex generators?
Are they supposed to add downforce, or are they there purely for drag reduction?

Thanks

 

Not too sure other than what Varis would tell you as I don't recall them doing any wind tunnel work. I'd PM Cheston and get his opinion on the vortex generators......

 

Ok thanks.
