Hello all,
I've got a Vauxhall Astra ECO4. The Astra is a common as muck car in the UK, but the ECO4 is a rare factory modified Astra to improve areodynamics. Basically, Vauxhall stuck on underbody panels, spoiler, thin high pressure tyres and a very low ratio gearbox. As the spoiler is only found on the ECO4 - the standard Astra spoiler is very different, I can believe that it improves areodynamics, so would using vortex generators to improve flow towards the spoiler help?
Here's a
couple images of the back of my Astra, and here's an image of the standard
spoiler on someone else's Astra.
Thanks very much for your time in advance!
